Not as common, though prefab cistern designs seems feasible and possibly cost effective though maybe more for underground homes, homes buried once footed/finished or root cellars which for now might not be as common as have been. I also wonder if anyone used the reefer trailers since seems like a better option than intermodal shipping containers due to being insulated already. Great videos as always! Thanks for sharing.

FYI - because of a lack of housing around Sinclair Wyoming at the refinery there during a shutdown a group of 4 construction workers took my idea (I was always reading about alternative housing. That made 5 of us) and the week before the job we leased a 1/2 acre from a rancher and built an octagonal straw bale house that was 30 feet across flat to flat outside dimension. A 6 inch post at each corner of the octagon and a center post for supporting the roof. We built a wood deck slightly off the ground and stacked bales between the corner posts. One flat had the exterior door and the other flats had window boxes built that were 18" deep with a single cheap aluminum frame window on each side so it was "sorta double paned" (we ended up growing herbs and stuff in them). So as the bales were stacked, a window box was substituted for a bale. Note that we used black visqeen plastic to set the bales on and when a wall segment was done we brought it up on the outside and inside to the top and stapled it to the cross beams going from corner post to corner post to encapsulate it for water proofing and air sealing. We then put 20 foot rafters going from the higher center post out to the octagon wall sections. We 1/2" plywood decked and tar papered the roof, then decided to put a layer of visqeen on top of that and some slats to hold it all down in the expected high winds we were informed of. Privacy walls of 2x4s were built to make 5 pie shaped (truncated point... For the cheap blanket hanging doorways in the center) bedrooms with the open main living area and kitchen taking up the rest of 3 remaining 'segments'. We got a local built 35 gallon steel barrel wood burning stove for heat and ran the vent chimney up through the roof. We stayed there for 4 months (and it snowed and blew quite a bit) and it was quite nice and didn't take much to heat. When we left we figured the rancher would just burn it down or something because he said just leave it, he'd take care of it. Note that the entire cost to build it was less than $500 back then, so individually it was $100. Since we were all getting per diem we made out like bandits! TWENTY-FOUR YEARS LATER I ended back up in Wyoming and drove my wife and kids there to show where I'd built the hay bale house and was surprised to see it was still there. Electricity had been brought in and the exterior was stucco and it now had a metal roof. Pretty good for a temporary shelter for "migrant" industrial construction workers, haha.

A builder near me built several load bearing straw bale houses for clients in the 1980's-90's. When he wanted to build one for his own family the banks and insurance companies put a stop to his plans. I've talked to the people who live in one of those houses and they say rodents are the biggest negative even though the bales were treated with a rodenticide before construction. Someone else I know built a similar house using baled cardboard instead of straw. He ran the cardboard baler at a large catalog company distribution warehouse. When he learned how much the company was paying to dispose of the bales he made a deal with them to take some for free.The walls of his house are 30 inches thick.

Thank you for a solid and honest overview of straw bale building. And yes, I would be hesitant to build one in a humid climate, too. My spouse and I designed & built a large 4000 sq/ft straw bale home we happily lived in for 14 years (until we had to move), and it was one of the best decisions we ever made. It was about 10% more expensive to build compared to traditional homes due to the more labour-intensive process, but the incredible insulation values meant that the cost of heating & cooling the place was minimal, offsetting the extra building cost within 3-4 years. We lived in an area with 37C/100F summers and -35C/-31F winters, and the house was never too hot or too cold. A smart passive solar design, open concept and lots of thermal pass was a big part of that, too. One thing about prefab straw bale walls, though: the flatbed trailer transporting those bulky walls to your site very quickly increases the home's carbon footprint...

Always a fan of the alternative construction techniques. Your critical review from an industry standard perspective only helps to increase their visibility and reduce the barriers to entry for more people to adopt them.

Great summary of strawbale construction Belinda! I love the idea and possibility of the prefab strawbale walls. We have lived in our Timberframe home with strawbale infill for 14.5 years now here on a small island on the southwest coast of Canada. The timber came from the property, island and neighbouring island. The home was built in the method of “workshop” for much of the building process. We still have people who come up to us and say what part of the house they worked on and what they did. There are some interior packed clay walls and one section of an exterior wall as well. The building has wide overhangs and wood on the south exposure side with the big windows that gets the most impact tour west coast winter storms. Many skylights on the metal roof keep the home bright and cheerful in any season. All the pros and cons mentioned in the video fit our experience of living in our strawbale timberframe home except for bug and rodents. These have not been an issue. The lime plaster walls are sealed and nothing comes in unless we leave a door open. We treat treat the home perimeter yearly against carpenter ants which because living in the woods is something everyone should do. Cornfield ants sometimes like to live under the cement pad of the home and can get confused and come into the house when they are leaving the nest but this isn’t because of the strawbale walls. So no concern with bugs and definitely not rodents in the house. Our lime plaster both exterior and interior has stood up extremely well and I am just this year starting to apply fresh milk paint to the inside walls. What we really love about our home though is how it quiet and breathes and how it is cool in the summer and warm in the winter. It is a sanctuary. We have in-floor hot water electric heat and a gas fireplace as back up for our many power outages during the winter. The home is modest at 1,200 square feet with high cathedral ceilings and surrounded by woods. If we ever have to move, this is a home we will be deeply miss. Ordinary homes just don’t measure up to this home. It seems to love us back in the way it wraps around us like a warm hug. Here is a link to my blog with some photos from about 12 years ago. The place has changed some since then as we added another main floor bedroom with wet room ensuite where the front deck use to be for aging in place: creativepotager.com/la-casa-de-inspiracion/

I grew up in central Texas. I remember the old homes with 13” thick limestone walls and deep overhanging roofs. Those thick walls were a great choice because they insulated the home. I also love the deep overhangs. So much light and yet it helped save energy passively. Do love to have a home with these features today.

@spiceweasel945

Actually stone provides no insulation, it is thermal mass. It will slow the transfer of thermal energy but acts like a big battery for heat or cold, reradiating it out over time. It’s a buffer, not a barrier.

Straw is not a "waste product", at least not on the farm I grew up on. Straw has TONS of on farm uses, bedding for animals, mulch for everything, ground cover, manure composting, and that's just the simplest most obvious ones. Ya, not a waste product by any means. Now that we have that out of way. You can use earth plaster on straw bale construction, as long as you have enough overhang to prevent direct rain. This makes straw bale construction not only low cost, but also possible to made entirely from local products, and I mean stuff found immediately around the house site. I also think that learning the skill involved in plastering earth plaster can be easily learned in a few hours of practice, which you can do while plastering your home. Bonus, even if you do a rubbish job at first, you can easily go back and repair your work as you get better at doing it. IF you live where you have suitable earth, and readily available straw bales, I"m pretty sure that an analysis would show that straw bales are an excellent and affordable choice. And truly very sustainable.

More episodes on straw bale and prefab walls with straw bale technology would be useful. Cross-over concepts of building straw bale barndominiums and tiny houses could be interesting and useful. Rapid resolution of permitting hurdles is an important topic too.

I visited a few strawbale homes over the years as well as other non-conventional building material homes. Those with strawbale homes always seem happy to build with the same material again. Not so with other materials, mud brick, rammed earth etc. Yes great content as always. Cheers from Oz

As someone who is dreaming of strawbale home for a long time, this video was exactly what I needed. I am especially grateful for the "disadvantages" section which showed me some things I was not aware of. Nicely done!

Sooo glad you are a convert! Personally, when I was looking at what resale of strawbales would be , I found they sold almost soon as they came on the market and sell at high prices. I don't think bugs are a real problem as highly compressed and sealed unlike stick built homes that are very gap ridden. Hand done home can have rounded corners, window seats and be very whimsically hand plastered. There was a whole thing prepandemic where an expert comes and oversees the construction of eager to learn people doing free labor and then people who had been to a couple of these invited more people to come learn for free labor. I don't know that I love the panels that much... do they have the same wind/ fire resistance? Found the website and they are only easily had in Europe and am weighing osb with covering vs plastering or concrete spray that keys into the bales for durability. looked at the price of the one bedroom tiny house and wow. Most strawbales in the book I bought were done for about $30 sq ft.

Those thick walls do have one advantage that makes them well-suited for building in the desert. It means that windows have built-in shading which means you get light without as much undesirable heat gain. Stick-built homes tend to omit shading on windows. One of my favorite straw-bale homes is in the desert of southern Utah. If I'm remembering correctly, it's about two decades old at this point and it's timber frame (i.e. the straw isn't loadbearing). One of the unique features of this house is the indoor lap pool, surrounded by windows along the south side of the house. It acts as a thermal and hygric buffer for the rest of the house. (it's kind of like an earthship in that way.)

Straw bail homes are a great idea, but super extra care must be take during the construction process. As a fire fighter I was present at a structure fire on a home the had a room in attic type detached garage under construction using the straw bales. The stucco had not been applied when we were there, the mobile home had a fire under the floor that was self vented out the side of the structure. Upon arrival the only thing other than the home in danger was the LP tank. We entered the home and started cooling the LP tank, within minutes of this starting the hot ash started the gable end wall on fire, in less than 5 minutes the roof was on the ground. During the build you are creating a fantastic fire environment, vertical stacks of straw. A simple spark off the saw could result in starting over or someone's life.

I’ve known of straw building for years, but this is the first time I heard about prefab sections! Thanks for introducing that to us.

I absolutely love the work you do, it is so clear and concise yet the most important information is never missing. You rock.

I have also read that condensation points can be an additional concern in colder climates, where the insulative properties of straw bales make them more desirable. In the cold winters, something like steel can attract moisture to condense inside the straw bale and cause rot. I'm not an expert on this topic though. I'm simply an enthusiastic bystander eager to see straw and hemp become more prevalent in modern construction. I think these type of structures are so beautiful! I love the thick walls, and the natural plasters. Everything about them look so...smooth!

It depends on whether the water is going to condense or not. So humidity alone will not be the problem but when combined with conditions that can lead to it. Humid interiors in cold climates for example could lead to problems. However it should also be noted that straw bales can take on an expire vapour, mitigating humid conditions. Something else to consider, wherever you use wood you can also use straw otherwise you'd be having problems with the wood structure as well. I believe John Straube has done research on the vapour storage capacity of straw.

We were planning on building a straw bale house. And still want to do this! Beside the insulation the instant “character” is the main attraction for us.

I think they have their place - a limitation not often discussed is humidity. If the ambient humidity is too high, they are not suitable. It isn't possible to 100% encapsulate and seal the bales.

I've recently started following your channel and I'm impressed by the amount of research per video - informative and easy to digest. I'd wish for more topics regarding buildings that are made out of concrete in other countries, though. Maybe... how to soundproof a concrete house that doesn't have any studs?

I discovered this channel only today and I have been binge watching the videos already. Kindly do more and more alternative construction videos. If possible, do make a video where max floors that can be constructed using all eco friendly Material from walls to foundation and the roof as well.

Thanks for making this. I'd love to see videos on cob, rammed earth, and masonry stoves.

Fantastic video. - thank you for your research! We are considering building our new home via ecococon panels in the UK. This really breaks down the pros and cons.

They seem best-suited for dry climates.

My concern about the prefabricated straw bale panels is that their volume makes transportation costs potentially untenable. I'm really enjoying your alternative construction techniques. Thank you for posting.

Thank you Belinda. Your channel is so informative. Could you please do a similar analysis on rammed earth construction? 🙏🏽

I've wondered if there is a method to seal the straw bales using some sort of polyurethane spray coating or like maybe even wrapping with sheets of thermoplastic like PET or other long lasting recyclable material where a vacuum can be applied for further potential insulating effects. Amazing how thatch and cob were more common at times in parts of the World. Sad the lack of regenerative and renewable resources use... though is good to see a flow versus ebb economic season main stream. Guessing something malicious wanted to own whatever they could get away with.

We used to build straw bale winter shelters for our dogs and chickens.

I was thinking to advice you to take a look at Ecococon. But I was happy to see that you already found them. These prefabricated elements are quite interesting. And the thickness of the walls are similar to what we normally (in newer times) build in Denmark.

Alternative housing builds 😁

I am good friends with the folks who created the Ecococon panels. It's quite a leap from straw bail in terms of the quilty and energy performance, it makes straw prefabrication walls quite straightforward on our passive house projects in Colorado.

A great video follow up would be a survey of straw bale projects and the details that make them "straw bale." I.e. most of a straw bale building is just a standard building, like a slab or raised floor & interior partitions, roof framing, roofing, etc. Also the cost per sq.ft. of wall comparison would be educational including the local cost effects (e g. proximity to source, local specialty suppliers...)

Architect Carr nearly attracting the audience of Munro live!

It is unfortunate people do not consider things like appropriate technology for the intended use, climate and energy involved in transporting "sustainable" building materials. I live at 7,000 ft and people here have made fences and buildings out of straw bale. When the bales crack and get water inside them, they rot and disintegrate. They can work in some areas, but if you have extreme humidity swings and extreme temperature swings particularly cold to hot, these are a disaster if not done right

I'm a huge fan of hemp

I am very interested in straw bake oanels, especially the panels with straw and mud compacted together to make it fireproof. I saw some mentioned in a book that were the thickness of dry wall. These would be useful to add behind drywall for remodeling. It would be nice to have loose straw coated with mud to use as a loose insulation material.

After hearing about the house in Nebraska, it made me wonder if the three little pigs story was written with the purpose of destroying a straw bail home market. I never would have thought a home built of straw would hold up so well. Every type of construction has its pros and cons. Diversifying the way houses are built. Using the ideal technique/building style, for the climate the house is located. Or buy used, lol.

This was fascinating, thank you! I was wondering whether you might be able to do a similar in-depth look at cob houses? It's a suuuper traditional technique still used by millions of people around the world today, but almost never seen in the West any more despite being the standard method for centuries before timber framing became popular

Thanks for this! My bf refused to believe this was a viable option!

Awesome 😻😻😻🥳🥳🥳🤗🤗🤗

I’ve attended a stawbale workshop, and learned a lot. They are very beautiful houses but the technique is limiting in what you can design and everything from foundation to plumbing to electrical becomes much more complicated.

Since the workshop I’ve been wanting to learn more about hempcrete and exploring a combination of that with a post frame construction.

Could you make a video about rammed earth construction? I think it's a technique that would have advantages in humid climates

Most of the downsides of bales are the same as for wood. As they are the same material, cellulose. Just bales don't dry easily once wet, so have to be kept dry. Though longer term the same is true for both. Considering the lumber costs this method should have exploded, but so few understand it. Austin TX has a written code for it. Though I feel it is all constructed slightly wrong which causes the wall height limitations. The walls need some method of staking them together to provide shear resistance (keeping them in a stack). So most put a high strength material though the center of the bale, like rebar or wood stakes. That method doesn't use the strength of that material well. It should be placed on the exterior of the bales and tied together between each course. Then the high strength material is on the outside where it forms a sandwich composite beam. The tying pinches the bales between, providing the shear resistance, but also adds bending resistance that center staking does not. The concrete/lime/plaster takes the compression, and the sandwich material takes the tension. Then building to larger unsupported heights isn't as large an issue and the walls are far stronger. It is also easier to construct as nothing is required to pierce the bales. On the issue on wall hangings, you can place wood strips between the bales at locations you expect to hang things. Particularly cabinets that carry higher loads. They can be installed either horizontal or vertical, and are a rigid connection point once all the plaster surrounds them. Some even leave the outside edge exposed which makes them easy to find.

I heard that regular brick-shaped straw bales are not that easy to find, since more and more machines are making cylindrical ones. I am more interested in straw/light clay, theoretically it could be close to the hempcrete in its characteristics.

You can spray on the plaster.

look into rammed earth construction. better than hay for fire resistance when combined with a metal roof..

??? As an architectural engineering student, I became fascinated with the idea of underground buildings. The insulation qualities are intriguing. Can they be built in a green manor? Are maintenance costs reduced? How much more costly might they be from traditional construction? Are they safer from fire and tornado damage?
