Want to learn the art of clay plaster?

We often think of clay plaster as something only to be used on a mud hut on a remote mountain. I find that people are afraid of using it in a modern context, and most definitely look alarmed halfway through the application process:) But clay is very versatile. Depending on how you finish it, it can look rustic or smooth, boho or contemporary, farmhouse or Bauhaus. This spring I was tested a little, as I had a flat in a town to redecorate. But I still managed to do it using clay paints and plasters, and I’m thrilled with the result. Render, sculpture, and clay paint— it’s all here. I really enjoyed turning what was a clumsy jutting separation wall into a feature. Even the internet engineer felt compelled to stroke it! “Are those bits of real straw?” he asked. “Wow, so cool!” And, you guessed it, this feature cost almost nothing to make. The only thing I bought was a bag of sand. The key to getting clay plaster to work in modern homes is a decent finishing trowel, and some equally decent trowelling skills. Using both a Japanese trowel and a sponge is the key to creating a tight, sleek finish that even suits an apartment. If you’re coming to my special clay plaster course in Romania this summer, you’ll learn how to use both to create the look you want. But it doesn’t end there. Clay plaster sculptures can look absolutely stunning on mainstream walls. I’m just loving the way my mud birds sit (or fly) on this surface. The contrast in texture between the smooth clay paint and the earthen sculpture really gives the wall a stylish look. Who would’ve imagined some mud and horse manure could work in this context? Did I say clay paint? Now, normally I mix my own clay paint from the clays around me (the bird sculptures have been coated in a homemade clay paint), but I also wanted to try some ready-made clay paint from a sustainable eco company I’ve happily used for pigments. I’m pretty sceptical about bought so-called eco products, as I mostly find it’s a bunch of greenwashed crap. But Earthborne do a good job of keeping the chemicals out of their clay paint while also creating a paint that you can slap on the wall easily and smoothly. The finish is gorgeous with a smooth, rich texture that contrasts perfectly with the clay plaster sculptures. It felt like applying double cream. Did I mention pigments? I’m a picky devil when it comes to colour, and I couldn’t find the exact colours I wanted on the colour chart. So guess what? I bought some Earthborne pigments (which are excellent and surprisingly inexpensive) and mixed them into a white clay paint. I just loved the results.

9 Pictures of How the Wall Evolved. I have to be honest—my curving wattled wall was a determination demanding labour of love. It also became the central feature of my barn, and I felt a huge sense of accomplishment when it was complete. Here’s the picture story of how it evolved from a couple of posts, to the clay painted show-stealer below. First I screwed some upright posts in place as support for the wattles. Then I grabbed my secateurs and headed for the hazel copse next door to forage for hazel whips. I really don’t want to think about how many days this took, but despite the time and effort involved, it was beautiful to connect with the woodland in this way. Extra Tip: It pays to collect a few whips at a time, and then weave them into the wall, otherwise they harden as they dry out and become trickier to manipulate. The wattle weaving begins. At the same time in the lower right gap, I began the foundations of my bottle wall. This was made just out of cob and bottles. Here’s how the woven wattles look from above. The whole structure becomes incredibly tough, like an enormous woven basket. I didn’t need nails or screws. The wattles are wedged in by themselves. About half way through summer, I was getting to the stage where I thought this effing wall would never be finished. But finally, as with everything in life, the day arrived when I wove the last wattle in place, and the whole process drew to a happy conclusion. Next job was to complete the bottle wall feature on the lower right. This was such a pleasant job. I used a cob mixture to embed the bottles. Once you're wattled up to the hilt, the first layer of daub goes on. Don't panic if it looks a right mess, because the first layer is supposed to. Clay, straw, sand, and manure went into this mixture. I remember people coming by and looking rather alarmed when they saw this. Inside I simply whispered, “I’ll show you, you wait!” The dust bin lid was screwed in there to create a truth window. Using a Japanese trowel, I began smoothing the subsequent layers of daub. In total there were three layers on my wall. Eventually I began sculpting the edging of the wattle wall and adding a few other sculpture details. Finally I created some clay paint from a beautiful reddish clay I found. I used pigments for the flowers. All in all I felt pretty pleased with the outcome.

Do you love the Mud Home? Does it inspire you?
The Mud Home has been completely ad-free for over a decade, but it doesn’t run on hazelnuts. So if you’d like to show your support and have access to a massive archive of updates, videos, and audio, please consider becoming a patron. If you’re planning to move off-grid, or even build yourself a little mud home, what should you look for in a piece of land? It’s important. Your land is the ultimate make-or-break factor in whether you thrive off-grid or not. The trouble is, if you’re coming from an on-grid set up, you probably won’t realise just how important some elements are, or which things are deal-breakers, and which aren't. Below is my list of top six crucial things to look for when choosing a piece of land to live in. 1. Water Water is life. Without it you can’t grow anything, wash your clothes, shower, or clean your dishes. You need it for building, for living, and for growing. And you need a lot more than you realise. You want to have at least one (and preferably two) water sources on your land. Don’t trust any agent or seller who says, “Oh I’m sure you could connect it to this or that source.” People always say this. Water is simply too important to take a chance on. You want to see it with your own eyes actually on the land.I’ve already written an in-depth guide covering this, so take a look if you haven’t already. Where does the rain water flow? It’s not all about finding water though. Sometimes it’s about getting rid of it. When the rains come, you need to be sure you’re not going to be sitting in half a metre of water. So study where the water flows. Sometimes there are gulches or ditches that will give you a clue. Lots of clayey soil around the living area is also a bit dubious. Obviously, if your land is basically a swamp, then it’s going to be tricky, and there’s only one way to be really sure, and that’s to visit it during or just after a big rain. 2. Sunlight It’s a common mistake for those who’ve come from an urban setup. The off-grid life is very outdoors, and the elements impact everything. If your land is north-facing in the Northern Hemisphere or south-facing in the Southern Hemisphere, you risk having very little to no sunlight hitting your land in winter months. The direction your land faces can cause drastic micro-climates, even within a matter of metres. Without sun hitting your land you will struggle to grow vegetables, you risk more severe frosts, and won’t be able to use solar power adequately. Not to mention the impact on your mood. Always south? In Spain my land was actually east-facing, but I was on the top of a mountain, so I still got plenty of sunlight, even in winter. However, the west-facing plots opposite me were sunless and frozen for three months in winter. Why? There was a mountain in just the wrong place that blocked the sun from them. So do note that it’s not always about the angle of the land. 3. Wood Many people forget this one. Unless you are on the equator and cooking using gas (not the most self-sufficient idea, but an understandable way to start off), then you’re going to need wood. The colder your climate, the more you need. It can be pretty staggering how much wood you burn in really cold climates. So, make sure you have some sort of wood source either on your land or next to it. Wood is heavy. You don’t want to be carting it miles up hill if you can help it. I like things like ash, willow and hazel copses or backwoods. If you are using things like hazel, willow, or ash, it’s actually amazingly sustainable, because these trees love to be pruned and regrow very fast. Those woods also burn very hot when properly dried out. Another option is to be positioned close to a wood yard. They always have off-cuts you can use. 4. Soil/Clay/Rocks Almost no one checks this, because no one values the earth beneath their feet. They’re about to start though, seeing as we’ve rendered half of it lifeless. Your land is made up of a treasure trove of elements, and if you take the time to look, you could be sitting on valuable resources. So dig below the surface a little and see what’s there. If it’s just sand, and you have dreams of food gardens, you might want to reconsider. Fertile soil: If your land was used for light pasture, you may be lucky enough to find fertile soil. This is soil that hasn’t been degraded by intensive agriculture, so it’s still full of the microbes needed to grow healthy food. It can be peaty and rich to touch. Clay: Gardeners hate it, mud builders love it. If you want to build a mud home, do yourself a big favour and buy land with clay in it somewhere. Clay isn’t a scarce resource. It’s everywhere. If you see hard, cracked ground on a dry day which turns slippery when wet, that’s almost certainly clay. Rock: Check what kind of rock is on your land. It’s a very valuable resource. My barn and two huts were made entirely from the limestone rock of the land, not to mention all the perimeter walls. There are many kinds of rock, and I'm not a geologist, but here are some common ones to recognise: Limestone: One of my personal favourites, because hey if it’s pure enough you could potentially make quicklime out of it. It’s also a good hard rock for building. Granite: Granite has been used for a very long time in construction. This tough ancient rock can be polished and turned into worktops, window sills, and much more. Slate: This flat black rock is very useful. If you’re in a slate area, you can use slate for roofing tiles (see Galicia in Spain). It’s also wonderful to repurpose it for plates, shelves, flagstones, and more. Sandstone: Softer than limestone or granite, sandstone is easy to work, so you can carve it into shapes. In times of old it was carved into oil lamps, statues, bowls, and more. It’s also used today for flagstones and building blocks. Other good things about rocks: If your land is rocky, you’re less likely to have flooding issues. Peat can potentially create bogs, and clay holds water, so it can create sludgy, water-logged areas. 5. Access Last but not least. Most people know they want to drive to their land, and access is one of the first things they check. It isn’t impossible to create a house without a road, but you’re opting for a fairly hardcore adventure if you choose do that. I personally don’t think you need the road running up to your house, and am happy to ferry materials 100 metres or so. But you have to know yourself on that matter. 6. Good energy. "I guess land with good energy sells fast." This is what an Qi Gong practicing estate agent said to me after I sold my barn in two weeks. He's right. I personally wouldn't give a damn if a piece of land had all the physical attributes above if the place didn't give me that special feeling. Land isn't dead and static. It's alive and connecting, and it definitely calls in (or repels) people. If you want to know more about this aspect, you might like my Earth Whispering course. Extras The next things are not necessarily dealbreakers, but things you may not have considered: Sloping or flat? If your land is sloping (and you put a home at the top of said land with drainage channels) you’re unlikely to suffer flooding, because the rain water runs down and away. The disadvantage of sloping land depending on the gradient is you may need to terrace the land for growing. Flat land has more potential to become bog-like, but is easier on the feet. Trees: Most people who come to this website are the kind of people who like trees, and are probably going to care which ones are on their land, so I'm probably preaching to the choir here. Trees are for me some of the most important beneficient beings to grace a given spot of land. They offer fruit, nuts, wood, shelter, shade, homes for birds and other animals, beauty, and if you can hear them, an awful lot of wisdom. Of course, some beautiful generous souls are going to reforest the land. It takes time, but it's a great thing to do. Wind: Wind is an invisible but powerful force. If you live high in the hills or in an exposed position, the wind may or may not drive you nuts. Wind can rip off roof tiles, break tree branches, and prevent you from lighting a fire, so it’s worth considering. The plus side is, you could use it for wind power. Altitude and snow: Is your potential land buried under a lot of snow in the winter months? Snow is beautiful, but just know what you’re letting yourself in for, because it’s hard work navigating the off-grid life in the snow for months at a time. Considering going off-grid? If you’re considering moving off-grid, then take my free off-grid prep course and ask yourself a few important questions before taking the plunge. If you’re serious about going off-grid, then I’d advise enrolling in my off-grid roadmap, which guides you through the first stages of setting up your off-grid world and may well save your sanity, marriage, and health in the long run. Two Options: You can choose between the Full Off-Grid Roadmap with 15-Part Video Series which takes you step-by-step round my off-grid world in Spain. It comes with an in-depth 117-page PDF. That option costs $80 USD plus tax. Or, if you have a limited budget, you can just buy the 117-page PDF without the videos, which is currently $45 plus tax.
Last month, I was travelling the byroads of France back to my barn in Spain. Now, I love the drive through Provence for the food and the glorious country roads. Sadly, most of the time as soon as I hit Hotel-Land, I have to grit my teeth and brace myself for a night in soulless concrete. Not anymore! For I have found the Permadise. It was late August as I swerved this way and that along the tiny bumpy road, fields of sunflowers rolling in yellow waves beside me. Finally I pulled into a remote stone hamlet, and there in front of me a young couple waved from the entrance of a massive stone barn. This was Dustin and Nicole. Dustin and Nicole are Swiss, and in their former lives Dustin was an engineer while Nicole worked as a mechanic. Yes, already we can see this is a powerful combo for a perma-natural building project. What they have done in five years here at the Permadise is pretty jaw-dropping. A huge barn has been completely renovated using natural and upcycled materials. You cannot imagine how happy I was to see lime mortars in the walls, upcycled wood, and straw bales. Then there’s the enormous open green house, and I kid you not when I say I was reminded of the Eden Project. Because I’ve never seen such a beautiful, creative way to make a hothouse for your tomatoes as this, and on this scale. Originally a massive ugly old metal hangar, Dustin and Nicole ripped off the corrugated iron and in-filled with all manner of second-hand windows and doors. The result blew me away. “So what made you move here? Had you always dreamed of this kind of life?” I asked the couple over breakfast. We were looking over a dreamscape of mulched vegetable beds, berry bushes, and fruit trees. It was a world of abundance. “I had an aunt who lived in the country,” said Nicole. “And I always remember visiting her when I was younger, and enjoying that experience, living close to nature with animals. We were living and working in Basel, a big city, where even the countryside isn’t really nature.” I nodded knowing exactly what she meant. There’s a huge difference between living and participating in nature, and having it simply sit there as a backdrop. “I want to be self-sufficient,” said Dustin, pushing a lock of blond hair out of his face. “I can see what’s coming, and if I put the work in now, I can create a self-sustaining permaculture food garden. Eventually it will take care of itself and us.” As I munched on my egg, probably laid by one of the hens clucking opposite, I revelled in the delights of living as a true Gaian, and talking to people who “get it”. “It’s always really interesting hearing why people start out on this journey,” I said, laughing. “I did it because I hate working! I just wanted to escape the grind. But once you live in the bosom of nature, you just can’t go back.” We all nodded at that. There was such a peace pervading the Permadise. It’s an atmosphere so different from that of the modern world we’re used to. It’s not just the quiet, but also the impact of eating home-grown food, the slow rhythm of the day, the sunlight and other elements, and the effect of living in an ancient building made with natural materials. Oxygen literally permeates the walls. Now, sometimes in these recycled Permie projects, things can look a bit of a mess one way and another, but the thing that so impressed me about the Permadise was just how good it looked. It was a place of beauty, and the building was as stunning as the garden. I really commend the pair of them for taking on this huge project in such a professional way. This gorgeous rustic door frame is made from wood cut from the land. The bathroom has been very creatively designed using natural wood forms, and felt incredibly luxurious. You can see all the walls have been mortared with lime. As is typical with ancient barns, there were gaps between the roof and the walls, which Nicole and Dustin have beautifully filled in with bottles and cob. One of my favourite features was this gorgeous staircase built from upcycled wood planks and driftwood. It is often the case that the most beautiful elements of a building are created to hide something. In this case it’s pipework. What a stunning flight of stairs though! So if you happen to be in central France and looking for a very inspiring and healthy place to stay, take a look at the Permadise. As you know, the Mud Home is ad-free and independent, so my recommendations are always from the heart.

This summer I was lucky enough to housesit for Charlotte Organ. Frankly it was a dream. Apart from being a lovely person whom I hit it off with immediately, Charlotte is also a professional chateau and castle decorator, specialising in lime works and trompe-l’oeil. Charlotte has been in the lime game a fair while. “I became interested in the beauty of surfaces as a teenager when I worked on a S.P.A.B. project [The Society for the Protection of Ancient Buildings] repairing a Devonshire medieval longhouse,” explains Charlotte. Charlotte has decorated some illustrious buildings, including Kilcoe Castle for Jeremy Irons. She studied Fine Art at Bristol and then began working as a decorator in and around the city. There she learned various decorative techniques such as colour washing, stencilling, distressing, rag rolling, sponging, marbling, and trompe-l’oeil. The ingenious part is that she’s transferred many of these techniques to lime in a way that is truly original. So buckle up your overalls folks! This is a master class in lime finish. Why do you need to use lime? Anyone who’s been around The Mud Home a while is no doubt bored of me banging on about lime, until they use it of course, after which they soon become a fellow lime evangelist. Lime creates a beautiful, dry, and healthy atmosphere, and if you haven’t had a go, you just don’t know what you’re missing. Lime is a natural fungicide and inhibits mould in damp climates. It creates a beautiful, clean finish, it’s inexpensive, contains no toxic chemicals, and boasts a very low carbon footprint to boot. You can use lime in many ways: mortars, plasters, limecretes, and paints. I have a full article on that here. But Charlotte has used lime paint in ways I had never seen before, to create truly jaw-dropping effects. Both in her own home and in a great many of her projects, Charlotte uses natural pigments to colour her lime paints, along with some interesting methods to bring out the colour. One technique I adored was how she created stylish and elegant walls by using stencilling. I had never considered stencilling on lime paint before! She sponged the walls with a pigmented lime paint, and then used pure pigment in the stencilling. It looks simply amazing. Above you can see another interesting technique. Here we have a base coat of pigmented lime paint with squares of pigmented lime painted over the top. The colours were brightened by going over the lime paintwork with liquid beeswax, thinned with turpentine. Proper turpentine is needed here, not white spirit. Another method Charlotte used was to paint the walls in a base coat of lime paint, and then paint over them using milk (casein) paints. Here we are again (above photo) in Kilcoe Castle, and Charlotte has created a distressed lime paint technique by rubbing the lime paint and then waxing it. Charlotte has used lime extensively in her own home, a beautifully renovated farmhouse in southwest France. I found it incredibly inspiring on all levels. In this bathroom you can see a vibrant turquoise lime paint on the walls. Lime renders and paints adorn Charlotte’s farmhouse. She agrees with me (as does everyone living within lime walls) that it creates a warmer, drier atmosphere. Even on the eye the effect is cosy, as you can see by the lime render and warm tones of lime paint on the staircase walls. You can see more of Charlotte’s amazing work (and there’s lots to see and be wowed by, I can assure you) on her Facebook page: https://www.facebook.com/eneffetdecor Her website is here: https://eneffet.co.uk Things to take from Charlotte’s work I often feel there’s too much worry about the rules of building works. Nowhere is this truer than with natural paints and plasters. I mean what’s the ultimate risk here? Your house isn’t going to collapse because the paint went awry. Charlotte has really proved that it pays to experiment and you can use all manner of exciting decorating techniques with lime. More about lime paint (and relevant links):

So if you believe it should stay open source and ad-free, consider making a pledge. The 3 Things You Need to Do: Believe it or not, mud homes work fine in wet climates if you build them right. What you need to understand at the beginning though is this: mud homes do not work like mainstream concrete and plastic houses, so throw most of your ideas related to them in the bin. What do you need to consider when building a mud home in a wet climate? There are three fundamentals you have to get right. If you do these three things properly, your mud home will be well set for damp climates. If you don’t do these three things, it won’t matter if you coat your house in concrete (ouch) or EPDM, you will encounter issues. 1. You need a rubble trench foundation. You do not want a concrete slab. I don’t care what the architect, the codes, or your mate Fred says, they are wrong when it comes to mud buildings. I feel like I’ve said it a lot, but if you’re new to mud building you may not have heard the news. Concrete wicks up water and holds onto the damp. It also doesn’t allow for water to evaporate. That is absolutely not what you want with a mud home. People have all sorts of erroneous ideas about foundations, but with mud homes the drainage is paramount. You want water getting away from your house as fast as possible. The rubble trench is the cheapest, easiest and by a long way the most effective foundation method for a mud house. If you are building earthbag, you can create rubble trench foundations like this: https://www.themudhome.com/rubble-trench-foundations.html If you are building another kind of mud home, then it’s basically the same, so still read that article. You can also watch this video, as it shows exactly how to do it. https://www.youtube.com/watch?v=eNN7T4fBQo4 2. The stem wall is very important. The stem wall protects the rest of your house from damp or accumulating rainwater, and stops your walls wicking up water. The stem wall is usually made of stone, and depending on your climate can be anywhere between 30-60cm high (above grade). If you are building with earthbags you can use gravel-filled earthbags instead (see the rubble trench article). Normally we start the stem wall below grade (below the surface of the ground), so it acts as water resistant footings. Once the stem wall is sturdy and dry, you start to build your natural home on top of it. Some people advocate a vapour barrier between the stem wall and the cob/adobe. I never use one because as soon as a waterproof membrane is added, evaporation becomes impossible. Water will quite possibly seep into your wall one way or another, and if a vapour barrier is there, it prevents fast evaporation. Your wall will stay damp. 3. You need a good solid roof with wide eaves. The roof is the hat of the house, and I’d argue it’s the most important part of the structure. For a mud house in a wet climate, you want nice wide eaves to protect the walls (a good one metre long). If you do this, you are going a long way to protecting your earth plaster from the rain. Other things you can do: Backfilling around the stem wall is another great and simple way of keeping rain water away from your walls. Guttering Installing decent guttering on your roof will help massively in preventing the ground below from getting soggy from rainwater run off. Lime Lime is the perfect substance for folk in wet climates. It “breathes” so it doesn’t obstruct airflow and allows any damp to evaporate. It’s also a natural fungicide. Use limecretes instead of concretes, use lime wash instead of paint. Use lime mortars for stonework. You may even want to add a bit of lime to your earth plaster. What you don’t want to do: Don’t cover your mud house in lime render or (OMG) concrete. Please. It’s a terrible idea. The clay in your mud house expands when it gets damp, the concrete or lime render doesn’t. It will eventually crack and fall off. Concrete will do something worse and stop the house breathing too, thus mitigating the half the point of cob/adobe in the process, and making your house damp and prone to mould. Notes about natural plasters People worry far too much about their earth plaster, in my opinion. I honestly don’t think it’s necessary or even a great idea to try and waterproof your plaster. The best thing to add to plaster to create a super strong but natural render is horse or cow manure. If you’ve built your footings and your roof well, your mud walls will only need a touch up every now and again, and frankly that’s quite good fun. Extra Important Tips from Kristen Krash at Sueno de Vida who has built multiple mud houses in a cloud forest: 1. "Make the rubble trench foundation wider than the stem wall by 12-15 cm." This is a good point, and often happens by accident:) 2. "I would emphasize that people don't attempt to use plastic "moisture barriers" or any such thing in very wet climate. Water passes from areas of higher to lower concentration. Always and forever. Period. Meaning water is going to find it's way under or through your "barrier" and then not be able to evaporate. It will just keep moving to an area of lower concentration. As in inside your house. 3. "Don't build little nooks and shelves and such close to the ground level in your interior walls. I know it's tempting to be like "oh I'll just store my pots and pans under this table in this sculpted little nook, how cute!" Yes it is, for a season. Then you will be storing mold. The plaster will crumble from being damp. Keep your walls smooth and hard for at least one meter above the ground." I so agree with this. I put my entire living quarters on the top floor of my barn for this very reason.

A big thank you to all The Mud Sustainers, and everyone chipping in! Mud mama Kim Fraser has been at it again! Kim’s magical space in Moray is turning into a fairytale empire. There’s a straw bale hideaway pulled straight out of the Shire, Baba Yaga’s hen coop, and now this fabulously funky little coorie hut. What’s “coorie”, you may well ask? The answer to that apparently takes an entire book to explain, so I’ll leave you to do the reading. But for the purposes of this article, the coorie hut is a feel-good place to snuggle up warm. It will indeed feel good too, because the whole thing has been made with loving hands, local materials, and my two best buddies: good old mud and lime. “She’s the result of using leftover materials to make something practical and beautiful!” explains Kim. I love many things about this little hut, but most of all I love that it has developed completely organically with plenty of idea changes. This is what always should happen in a build. The idea that an architect creates an exact plan and your poor house is bolted to it like a prisoner throughout the build, is a very modern situation. So, how was this quirky little beauty built? Let’s take it from the bottom! 1. Footings and stem wall Now, this is a tiny structure, not a two-storey home, so there was no need to go overboard with the footings in this case. “The base was made with limecrete and stones found on site,” says Kim. This means the footings and the stem wall are all in one. All mud buildings need a stone (or similar) stem wall to protect them from damp and big rainfalls. Just for the record, for most larger mud buildings you want gravel footings. It’s simply the easiest, most effective, and incidentally the cheapest way of going about it. Ditch the concrete pad idea. Just forget about that whole thing. That’s another kind of construction which isn’t beneficial for mud buildings. 2. Willow wigwam and mud daub Next a framework was built using willow. This is a slightly different take on wattling. Basically you can create all kinds of mud (or indeed lime) structures using a wooden framework of some kind. “She evolved from a willow wigwam to her current form using straw dipped in clay slip for the base layer then an earth daub with lots of straw to retain some warmth.” 4. Roof At this point Kim still wanted her coorie hut to be a dome without a roof. I’m not going to lie; I raised my eyebrow at that. You can read all about why here. Nevertheless I was curious because heck, if anyone could make a mud dome work in Scotland, it would be Kim. However, eventually she decided to stick a roof on as a canopy. “Our Workaway volunteers helped with the process and built the wooden roof splitting old logs left from another build. One side is thatched using fireweed, the other side is covered in shingles made from old leftover wood.” So you see? There’s no reason everything has to be uniform. Kim used whatever resources she had to hand, and actually this two-part roof is one of my favourite features. 5. Painting and decorating The coorie hut was painted with lime wash and stained with natural pigment, which is a clever way of getting a deeper colour onto lime wash. Later this year, once the threat of frost had receded in late May (May? Good Lord!) Kim laid a limecrete floor with the help of a volunteer called Georgie. But it’s far from over. “The Coorie has taken on a life of its own, and continues to evolve!” said Kim. More clay plaster is being made as I write, so hopefully there’ll be an update on this later on. n Why the Coorie Witches’ Hut is so inspiring. Finally, there’s one other major thing I love about this build, and that is that Kim et al. have taken perfectionism, hacked it into roughly hewn hunks, and thrown them on the coorie fire. The last anyone saw of them was in smoke form leaving the chimney. Perfectionism is a curse many of us are burdened with (ahem). It can (and routinely does) completely scupper a build, stopping anything from manifesting, or slowing it to the point everyone loses heart. This little woven hut is going to be very inspiring because it is a wonderful, happy, and lovely example that you don’t have to (or even want to) have everything machine-perfect when you build with mud. In natural building you can play, experiment, change your mind ten times, try new techniques that no one has heard of, have a rough edge or two (or even make a feature of them), ditch uniformity, and create a beautiful organic space that people are dying to sit inside. You could actually stay at Kim’s and see the Coorie Witches’ Hut for yourself. Book a place at the award-winning and gorgeous Hideaway Under the Stars. It is absolutely no surprise to me that Kim’s place has a flawless five-star review record on Airbnb, as I stayed at hers once myself:) Follow the Hideaway on Facebook: https://www.facebook.com/hideawayunderthestars Follow the Hideaway on Insta:https://www.instagram.com/hideawayunderthestars Do you enjoy the Mud Home?

Now, I always say don’t build a free-standing exterior earthbag wall (ie. a garden wall or retaining wall), as they are so hard to plaster naturally and keep waterproof. But every now and again someone proves me wrong. Luke and Kath in New Zealand have created some mud magic here, which just goes to show, you should always take advice from experts with a pinch of salt:) Luke and Kath have done a stellar earth plastering job here, and used multiple techniques to create a waterproof and natural finish. So yes it can be done, but it takes some know-how and patience. Happily for us they have generously shared their process and photos with me (and now you). “We are in the far north of New Zealand. The climate here is not ideal for earth plaster, hot and dry for three to four months over summer and then usually a couple of months of very wet weather over winter. We are on a hill so the wind can at times be powerful and incessant,” explains Luke. Yes, New Zealand certainly wouldn’t be the first place I’d be itching to stick earth plaster out in the elements. But this funky outdoor kitchen has stood three years so far. How come? “We applied our first coats of lime/earth plaster, onto an earthbag wall, three years ago, with the help of your course. We did two coats at that time, then burnished the whole lot. It has stood the test of time well. The main issue has been a type of creeping grass which sends its tentacles out and under the earth, popping up under and through the plaster. Areas under the drip line of the roof have also weathered significantly. Portions of the sandbags had become exposed so we decided to redo the whole lot,” Luke told me. My first comments would be that the plaster in these photos looks exactly how you would want it to if you want to stand a chance of creating a waterproof finish. There are no cracks, as the whole lot has been burnished very well (in this case with the back of a spoon). It takes a bit of practice to get this skill off to a fine art, and Kath and Luke have mastered it. One thing we will want to know of course is what was in that earth plaster mixture? The result is heart-warming because so many of the materials were foraged from the land. This was one of things I wanted to achieve with my earth plaster course. I’m not against people buying ready-made clay plasters, but it’s definitely not necessary. You can create amazing plasters using the ground under your feet, and without buying anything. Here is how Luke and Kath made their water-resistant plaster, but be advised, don’t attempt to just copy this and think it will work. They are using their own soil and clay and sand, so it’s not a standardised commercial product. “We used the same formula of plaster we devised from experiments before doing the initial coats. 10-15% lime, 20% clay/straw, 2-5% cow manure and the balance of sand. The clay we sourced from the stream at the base of our valley. Our soil is basically sand so once sieved is perfect. The manure is from the cows next door. We used hydrated lime (https://www.graymont.com/en-nz/products/hydrated-lime) and mixed with water first, as cheap lime putty is simply not available here. Once applied, we burnished the whole lot like the first batch, as we found that technique to be highly effective at making the plaster weather resistant.” Animal dung, a bit of good quality lime* and some decent burnishing. This is why this plaster has endured. Now Luke and Kath want to take the plastering further. This time they’re going to add some layers of linseed oil to the wall too. *Luke and Kath used a high quality hydrated lime instead of lime putty.

All patrons have access to an archive of exclusive videos, and other posts. There are three main ways to create a gorgeous natural home for yourself. You can either build the thing from the ground up, find an old structure and renovate it, or buy someone else’s project. I’ve now done two out of these three, and have been considering the pros and cons for a long while now. So here is the Mud Home take on the matter. Build from Scratch (Green Plots) Pros:
Renovating (Brown Plots) Pros:
Taking on Someone Else’s Project There didn’t used to be many modern natural builds to take over, but that is definitely changing as more and more people try and set up alternative lifestyles or permaculture-based homesteads. So these days you could find yourself taking on a project that someone else has half-finished, or perhaps completely finished. This method brings its own raft of considerations, bonuses and headaches. Pros:
Be Generous Folks! On that note though, it’s such a downer when people take over someone else’s project and start blaming every failure and every problem on the previous owner. It’s just not conducive to success or happiness, and ignores how incredibly difficult those beginning couple of years are when you first start a project. The attitude of gratitude builds dreams in my opinion. It’s the make or break of a good life. See what the previous owner gave you, rather than continually moaning about their mistakes. There is probably some similarity between you and the previous owner, which is why you were drawn to the same land, and at some point you have to take responsibility for choosing to become the new guardian. Extra Things to Note Many of the pros and cons depend on the particular building regulations in your area. In Europe it is sometimes easier to get through the red tape by renovating. I said sometimes, because hey there’s enough red tape around here to encircle the planet three times over. Do you enjoy these articles?

First, we have to be honest that when it comes to the roof of a home, it’s hard to create a totally natural and fully waterproof canopy without some kind of vapour barrier. The roof is the most important part of a house. I’d argue it’s more important than foundations. Case in point: my barn has no foundations to speak of and it’s been standing 200 years. But as any local here will tell you, if the roof on the barn goes, the barn has no more than a few years left before it collapses. Upshot: If the roof is secure and functioning properly as a rain shelter, you’re good. If not...agh. So, many times it's going to be hard to get away with making a watertight roof without a vapour barrer. What did they do in times of old then? Well before the modern age and vapour barriers, people still made weather-resistant roofs. But...here’s the painful truth of the matter, they often needed quite a lot of maintenance and repair. Residents were also used to sporadic leaking, and roofs had to be retiled, re-thatched, or re-mortared from time to time. That was just how it was. Not that modern roofs are maintenance-free either of course, but there is one crucial difference: most people in olden days weren’t building alone. They worked as communities. Re-tiling a roof is pretty easy when there’s a crowd of you, but doing it single-handed, or even as a couple, is a lot slower and more tedious. Anyway, here are your six beautiful natural roofing options, plus whether or not you can get away without a vapour barrier. 1. Living Roof In my opinion the sturdiest of the lot. I love a living roof. I have two articles on making living roofs. Here’s how I made mine and here’s how Cath Coffee in London made hers. Pros: If made properly they don’t leak, can’t crack, animals can wander all over them without breaking them, they’re hurricane proof, soundproof, and possibly help retard a fire too. Basically no maintenance required once it’s built. Cons: These are heavy, so you need a decent roof structure to support the weight, which could end up being the equivalent of a couple of elephants (albeit spread more thinly). You’ll need some plastic, which is of course the devil these days. Also, a living roof really needs a damp climate to actually be ‘living’. Vapour barrier? Definitely. You’ll need two in fact, to be sure of success. Something like an EPDM or bitumen will go over the roofing boards, then you’ll need a couple of sheets of plastic as a root barrier. 2. Tiles Tiles are of course some of the oldest and most widely used natural roofing options in the world. For centuries at least, people have been firing clay and turning it into pots, amphoras, and roofing tiles. I confess tiles aren’t my favourite because they’re so frickin’ fragile, though on the plus side, they can look beautiful, and you might also get away without a vapour barrier with them. But tiling is definitely a two-person job unless you want to get rather tired. Pros: You can use them to catch rainwater (big plus), beauty, simplicity. Possibly no need for a vapour barrier. Cons: Fragile, can’t handle much falling on them without cracking, prone to get ripped off in gales, repairing tile roofs is annoying. Vapour barrier? This really depends on which tiles you’re using, and how desperate you are to stay perfectly dry. For the more modern, interlocking roof tiles, if it’s an exterior roof, say a porch or a shed or something, you can easily get away with no barrier. But for a house, and for the old school Mediterranean curved tiles, a breathable roofing membrane under the tiles is usually recommended. 3. Slate If you live anywhere with slate (such as Galicia, Spain) slate slabs make amazing roof tiles. They’re more forgiving to lay, and a bit less likely to get ripped off in the wind than traditional terracotta tiles, because they’re flat. Pros: Sleek, easier to lay than terracotta (in my opinion). Good for rain harvesting. Cons: You really need to be in a slate area to make a slate roof feasible and sustainable. Like other tiles they are potentially a bit leaky. And you have the issue of repair when the slate slabs crack (because a tree branch fell on them or something). Slate tiles are also fairly heavy. Vapour barrier? See my comments on terracotta tiles above. 4. Thatch Oh, who wouldn’t want a thatch roof? Romantic, completely natural, and super snug too. Thatch roofs are usually made from reeds, but people do also use grasses (though grass will last far less time). If thatch is made professionally it is nice and weatherproof too. So what do you need to consider? Pros: Insulating as heck. And of course thatch is so beautiful. Cons: Fire risk. Thatch needs decent maintenance. Vapour barrier? Ah well, according to the experts this all depends on if it’s a cold or a warm thatch roof. Here’s a good article explaining when and when not to use a vapour barrier with thatch. 5. Madras Roof (Brick and Lime Mortar) One of India’s traditional roofing techniques is a method called the Madras roof. Bricks are laid at a 45-degree angle over the rafters and mortared using a special lime application. Karen Shetty explained how that was done here. Pros: Beautiful, inexpensive, perfectly natural, honouring tradition. Cons: Fairly heavy, so decent supporting rafters are required. Like thatch, if you are dead-set on an optimum job, get a professional to lay this kind of roof. Vapour barrier? Normally vapour barriers are not used in India with these roofs. 6. Bamboo Roof Ooh if I lived in a climate with bamboo… Bamboo is nice and sustainable, doesn’t weigh too much, and is a material geared to creating gorgeous roofing structures. There are two ways to use bamboo in roofing. Usually you see the bamboo used for the frame and then some sort of thatch/reed roof over the top. But you can also use bamboo cut in half to form a kind of crenellated roof which would be excellent for rain harvesting. How to make a simple bamboo roof: https://www.youtube.com/watch?v=CZnMWDI6soo Pros: Inexpensive (if you are in the bamboo zone), sustainable, lightweight, cool. Cons: Bamboo can go mouldy if not treated properly. Vapour barrier? Because bamboo roofs are usually found in warm humid climates, and because bamboo is pretty efficient at channeling away water, I’d say it would be a bad idea to stick a vapour barrier underneath due to the risk of mold.
