A rather appealing modular home
 

too cold for our climate. Still nice, though.

I wouldn't be too sure of that. Assuming good air sealing, and a 6" (150mm) thick cardboard wall (essentially cellulose), you have a home that is likely more thermally energy efficient than the majority of homes today.

Can't make up their mind as to whether the house is supposed to last at least 100 years or 50 years. I guess it depends on how magic the glue is. Kind of reminds me of the roofer's lifetime guarantee -- the life of his business, which he changes every 5 years.

Interesting concept. The marketing dampens any enthusiasm I may have for it.

It's an interesting design, if we look at it as a reinforced-plastic house. Anyway, it does look nice.

Nice enough. The rounded edges will inhibit vortex formation. OTOH:

• Potential for roof leaks every 1.4m.
• 3 segments for 25.000 euro? No bath or kitchen?
• Ceiling and floor have the same finish material, softwood veneer. Is you house that way?
• Why no hemp fibers? Why?

This book will show how limited its possibilities are.

From 1974, 133 pages of hippy sh-tuff, an exhaustive inventory of non-cubiform geometry, and a unique means of 'sphere-point raising'. I treasure my copy, along with Zomeworks and the Dome Cookbook.

The cardboard could be made of hemp fiber...

There might be some way to seal those gaps and avoid roof leaks.


The cost really doesn't seem to justify.


That might be an Euro deal. I've already seen a few colonial houses made entirely of wood, from their ceilings to the floor.


I guess sourcing the hemp fibers would be the issue, but there are other crops that could be used for the same purpose.

Seals = potential leaks. Not saying it can't be done, with tongue and groove or O-ring seals. But lapped or guttered seams, or post-tensioning would be my preference. A detail cross-section would tell the story.

Colonials prolly didn't use softwood veneer for flooring. More likely hardwood planks. I know raw veneer is a euro-scandinavian thing. Back in the 50s in the PNW they made veneer from old growth timber with really nice graining and then sand-blasted it to give a nice 3D texture.

Hemp is an annual crop so production can ramp up quickly once the artificial constraints are removed.

I was thinking about those silicone-based glues used by plumbers and some mechanics due to their resistence to moisture and extreme temperatures.


At least in the 3 southernmost Brazilian states some native woods such as Araucaria were used, but that's not an easy option anymore.


I'm not so unfavorable to industrial uses of hemp-derived products, or even medicinal applications. A few friends of mine actually engage in "recreational" use of marijuana, but I have some objections to it.
