Love this!

There seems to be a trend toward smaller houses (tiny homes), as well as ec-friendly construction and reduced carbon footprints at the moment - and this fits them all nicely.

On first viewing, I thought this was a "buried" house, but the green roof is just placed on top. I wonder whether it'd work equally well built into a hillside?

If you check their website, there are a few different design and size options too (number of bedrooms).

I prefer mid-century modern, Scandinavian design (minimal, of course), so this isn't for me, but I can certainly appreciate the idea.

Great hunt @deong
