Biodegradable home built by hand with cork LEGOs, no glue

Using 1268 cork blocks, Matthew Barnett Howland built a home almost entirely by hand that uses no glues or mortars and can be disassembled at the end of its life.
Designed by Barnett Howland, Dido Milne and Oliver Wilton (who appears in the film), Cork House can be assembled like a “giant, organic LEGO system” using blocks built from cork waste from the bottling industry. With numbered blocks and detailed plans, one person can lift the blocks and place them one on top of another. “From the slab up it's simpler to assemble than some LEGO construction kits that my son was building when he was about 10”, explains Wilton.
The expanded cork blocks are structural- working in compression they take all the downward load-, but there is a bit of wood in the structure: wooden beams for lateral support on windy days and weatherboarding to protect the roof from rains.
Cork dates back thousands of years in construction- Romans used it for roof sheets-, but the technology for shaping the cork blocks for this kit house is very modern. Working with the robotics lab at The Bartlett School of Architecture UCL, the architects developed a robotic milling method for cutting highly specific shapes to deal with water and airtightness issues. The resulting blocks fit together with a snug “interference fit” of the tongue and groove.
The home is completely recyclable and thanks to the mortar-and-glue-free bonds, it can be disassembled quite easily and even composted (though the natural resin holding the blocks together makes this a long process). The team tested out the assembly and disassembly on a smaller structure “Cork Cabin.

[@curmudgeon1933]

When I lived in Portugal I saw many areas planted with cork oaks. Recently there has been a move towards using plastic wine stoppers. Surely the cork farmers would be delighted to find an alternative market for their crop. As I understand it, cork is not only a wonderful insulator, but also insect and damp resistant as well as being much lighter to transport and work with, which makes it less labour intensive for the construction industry. One question would be, when the blocks are being formed originally, would it be possible to mould them into the dovetail block shapes to remove the need to mill the complex shapes?

[@reddrummaster]

Another major advantage of cork is the incredible sound proofing of the house. Compare that to a brick house were you need to fill it with curtains, carpets, textile furniture to keep the echoes out. I listened this episode on my headphones and you can really notice how great the sound is in those rooms.

[@TimothyArcher]

@Kirsten Dirksen , Wow, this is blowing my mind, on several levels! The Expanded Cork block system is amazing, in and of itself, but the buildings shown here that are constructed from that system, are so innovative, practical, and quite beautiful. I have enjoyed working with wood for many years, and can hardly believe, how little I knew about Oak trees, especially the fact that their bark is Cork! Beyond that, I never had any idea that Cork had such characteristics, as would make it viable as a structural building material. After hearing the gentleman refer to the Cork tree as "Cork Oak", I took the time to do a quick web search on the term. I am amazed at how much I learned about Cork and Oak, in just a few short minutes! For example, Oak trees belong to the genus Quercus, which are a subspecies of the Beech family. All Oaks are deciduous trees, meaning that they bear broad leaves, as opposed to needles; however, while some species of Oak shed their leaves, other species are Evergreens--yet are also deciduous! I never knew that any such tree existed, that had this combination of characteristics! And there are more than 600 species of Oak, several of which grow in various regions and climatic zones, world-wide. While I knew that Oak trees were not limited to North America, and that numerous species also grow throughout Europe, I had never known that some Oak species even grow in the Mediterranean region, in the Middle East, in Asia, and even in North Africa; nor that some species produce berries, while others produce Acorns. I learned all of that, in less than ten minutes, thanks largely, to a Wikipedia article that turned up in my web search. I find all of this to be utterly fascinating, and am intrigued enough that I want to commit some more time to researching Cork and Oak trees. Thank you so much, for yet another incredible, fully enjoyable episode. None of this educational odyssey would have taken place, had I not watched this video! I love the work that you and your husband produce. Your channel is one of my most favorite on KZbin! ♥️😃👍🏼

Did they say in the beginning something about using cork left over from the wine industry? Like how much wine are people drinking? Because yeah it would only be a good thing if they could do it from waste cork maybe people could start recycling it like they do with Metal /paper not that that so-called establish recycling happens as it should all is presented is doing. Here in Australia apparently we've been chipping out recycling overseas for ever and now they don't want to and it's all gonna go to shit pretty soon I'd say. And I only became aware of this a little more than a year ago maybe and most people I've asked haven't been aware of The recycling farce as it is in Australia. So nice idea but maybe not so feasible with the cork bricks ATM

@Victoria Marshall; I'm thinking that all that plastic China isn't accepting could be melted into blocks like this cork house uses. Only need to over come the photo degradation from them being exposed to light. Maybe design a living roof and vine covered walls. Or paint the outside.

[@victoriamarshall2212]

AnantaSesaDas I think the justification for not recycling most things is cost unfortunately it's just cheaper to buy new plastic then it is to recycle old plastic same as paper same as practically everything/resource on this planet. I mean surely there must be a way to recycle or reuse say cement from the constant building and tearing down buildings all over the place but no sand is apparently cheap to buy it's like ridiculous. I got called crazy for carrying 6 30 kg bags of sand one at a time about 2 km from where they were just thrown into a rubbish skip bin ,completely brand-new ,just because they were left over after the job was finished. The amount of people that couldn't understand why I would prefer to use something which would otherwise go to landfill rather than buy it new it's not the money. I would love to see used plastic utilised but well money calls the shots like so many other good ideas it's doubtful this will happen in the near future . Well I can say is since the whole world seems to be ,for the most part totally insane I don't really mind being called crazy .🙃

[@josesimasyt]

I lived in a house with the inside covered with this kind of cork sheets maybe an inch thick. It was great but we ended up painting it over because of the dust that would come out of it. It also nicks quite easily in the corners and we ended up adding wood corners. The insulation was not outstanding and there was condensation and mold on the inside in places but that may have been due to the paint.

[@KH-ur9ed]

I'd be curious as well about the long term water issues. He said that in clinical testing the roofing proved to be absorbing water so they put treated wood slats to wick away the moisture a bit. However I would be concerned about the side walls and how it handles repeated freezing temps if there is water within the walls.

[@josesimasyt]

My experience is with internal usage only and in Lisbon, Portugal where temperatures rarely go below zero centigrade. There are several types of cork aggregates with different densities and weights. For example, on that house, the top floor also had cork on the floor under the carpet. These were much denser plates so that they could withstand the furniture. They have worked remarkably well to this day some 35 years later. I am sure you can find a grade that would satisfy those conditions and the house in the video is at a place that freezes regularly without any such issues (although only time will tell). I think it is great that anyone could just stack up a house without a lot of machinery and trades people.

I actually appreciate the fact it was built by 2 people, uses no other joining material or supports.

Brilliant! What I like about this is that it shows that with the right material you can have great potential for automation making housing much more affordable. And with the right design (don't really love the architecture here but anyways) you could even layout channels to make installation for electric and plumbing really easy. I could imagine something like this could also work with something like 3D printing with expanding foam. Or some kind of advanced foam that is stronger and UV stable. First print roughly then mill into precise shape like in the video. Basically an example how 3D printing home could work by automatically(?) subdividing a building into blocks to be produced and then assembled. Cork is awesome but clearly you don't have a very large supply of it. Or maybe some kind of fungus that you just feed and it grows into something like cork that can be scaled up in a more industrial process.

The fixhures and fittings are excellent. I love the addition of the (reclaimed) CLT spruce used for the wardrobes, door thresholds, shelves, beds and kitchen furnishings, which balances the darkness of the cork. I was worried about wind and fire damage but he seems to have covered those hazards. What l am unsure about is probably more psychological as someone could just get a chainsaw and cut through the walls potentially so l"d feel vulnerable. Further, it's a little dark. (Bottle corks are not so dark therefore l guess it's the 'annealing' process under pressure that chars them or discolors them, l guess.) Was there no way of naturally bleaching them? The ziggurat style roof enclosures, although providing the house with a uniqueness and charm, giving it a cottage feel, for me seems a much underused space. I am sure that could have been solved with a slight alteration to the roof blocks' internal design by slicing them so they're smooth and would look more like the ceiling frieze in the bathroom snd would have yielded more space. You have almost the same capacity up at roof level as you do below, or perhaps only 1/3 less. Were you not tempted to cover the cork with a brighter veneer facia? I know you want to see your lovely cork brickwork but you could have put a strip of glass or perspex every 6' so the cork could be seen. That would strengthen the structure too. I hate to be the messenger but l know the first purchasers will immediately spray the walls white (or their desired pastel) to brighten it. The other alternative would be more lighting. I would have been tempted to build 2 levels and make the pyramid rooves shorter: that way the beds would be closer to the roof lights and the stars above. All my personal suggestions aside, the Architect builder is obbiously highly talented and deserves to feel proud of such a magnificent example of outside-the-box ideology in this grey-glass breezeblock realm we find ourselves inhabiting.

Hard to say if cork will ever be available on a truly mass scale, but it may make sense in the regions cork is manufactured and the waste used for these blocks.

Let me tell you a super cool product. It's modular, affordable and completely renewable. It's called wood.

it looks great but how is sourcing your home materials from the trees of one forest in portugal sustainable?

[@Zone10Permaculture]

They use the leftover waste.

I would def harness water for hydro energy if I lived adjacent to a water course

[@larrymullins3853]

In the 1st world you can't have anything for free. Governments need their cut. Licences and permits will apply I am sure...

[@mattwoodproperty]

Larry Mullins no permits in uk

I was thinking the same thing when they showed the water power raceway being unused and wasted. But I am from north Texas, our flowing surface water comes from the last thunderstorm or the 'water' treatment plant, we don't have 24/7/365 water flowing, except in pipes.

[@captainkidd1234]

Note his excellent choice in safety footwear for working with nice light cork blocks. On a serious note , I wonder how many Building Inspectors would want certified installers and engineered drawings for such a simple and beautiful do-it-yourself project...

[@geocyo8835]

I'm kind of disappointed that Kirsten didn't ask questions about that absolutely beautiful bathtub and sink. It's obviously a custom job. I would like to have known how much it cost to have them made and where they were made. Also would have been a good time to talk about the plumbing as it relates to the cork's lifespan. Like is there something to guard against rot?

[@ashleyavinger4736]

I'd be curious to know the cost of this. It's such a beautiful concept!

[@Iguana93]

For building materials, this is really great and that is obviously the point here. But a lot of the internals are obviously designed by someone who didn't think too much about cleaning - the sinks in particular look like absoulute nightmare. Wooden planks around a brass bathtub without any seal around is a perfect recipe for rapid water damage.

[@nickway_]

Why not mold it into its final shape, rather than milling it out later?

[@nickway_]

​@@pootatotree7546 That makes sense. To be air/water tight machining is probably the best way. I also wonder from a cost and manufacturing efficiency point of view. Perhaps they can reuse the material they cut away in subsequent blocks? And/Or if they just use one common mold (or a few?) then machine away from there, thus saving the time and expense?

[@BushImports]

Thanks Kirsten, that is interesting. I wonder how the thermal properties compare to the foam?

[@geocyo8835]

I think this would make for a nice garage with the right fittings.

[@MaximC]

Man, if only they made available these building blocks...

[@raydreamer7566]

What do you do with the shavings that your robot milling process create ? I would like to know if these shavings could be mixed with any type of concrete ??? Great video ....

Cost of cork construction ??? . .

[@victoriamarshall2212]

Steve Mac yeah that's what I want to know

[@parxcel777]

I went to their website and it states that it is approximately £6900 and two people could build it in a week.

[@cellardoor7500]

Patricia Raymond 7000.00 for the entire thing?

[@thomaswestgard4379]

LOL, not sure what went into that 7000 number but maybe accurate if it’s ounces of gold.

How is the timber attached to the cork roof

[@andicastro1203]

I sold flooring for years. Buyers were few, but they were ecstatic about the beauty and functions. I would only use cork in my open house.

[@alexanderchang4597]

What happens when animals scratch away at the cork? Also, doesn't unlaquered brass contain lead?

[@wendyweaver8749]

Alexander Chang - It does. I read a few of the listed articles from this Google search - "Does unlacquered brass contain lead?" - and it appears that most unlacquered brass contains from 5% to 8% lead. However, the lead is not considered to be a health issue (perhaps it is if someone were to frequently suck/lick the unlacquered brass over a period of time) when not used in piping or fixtures for water that will be drunk. It looks as if this house has copper piping (or lacquered brass) with unlacquered brass for sinks, surfaces, etc.

[@JR-HeavenonEarth]

Is this cork home too hot in the summer? How would a cork home fare in a hot climate?

Very cool ideas. This would probably pair really well with hemp elements.

What type of fastener works best on this material?

[@kpoper01]

When will I be able to buy this cork building material and how much will it cost per cork block?

[@sanjuansteve]

I imagine the most common block styles could be molded so that only the specialty blocks would need to be machined.

[@joeykennedy7]

Kirsten! I have been following your videos for a few years now! This rates as maybe the best. Its because its a possible structure the un-educated could build and thats why i follow. Learning to my build my own house but I want it be sculptural beautiful art!!!!! THANK YOU SO MUCH AND I HOPE TO SEE MORE OF THIS!!! AMAZING

[@stevegerber169]

Since the blocks are just stacked without any fasteners wouldn't the structure just get torn to pieces by the high winds of a hurricane or typhoon?

[@TheAnantaSesa]

Oh any flood that covers the top might just float away the blocks layer by layer. But 2 metal wires criss crossed over the top could hold it down.

[@mariansmith7694]

[@BogdanWeiss]

Great contents ( as always.. ) BUT it would be great if we had some insight into materials & construction/machining costs some of these "designer/architect" do not translate well when cost is considered..... my "10 seconds of research" 5 axis Kuka CNC @ 100 pounds/hour in the UK x 1300 blocks = ~ 20K british pounds just for the machining of the blocks No need for paint & self assembly is a massive bonus - total project cost breakdown would be awesome to know....

[@JustCameronAndHisJeep]

I love it... It would suit a Canadian winter or summer. I am concerned about high-winds, but they seem fairly comfortable with its resilience.
