That could be handy in winter.. central heating.. ;)

Good point Gordon.. I was thinking and said HAY, which straw is not, and so perhaps spontaneous combustion would not be an issue, but surely the other points would remain.. ie would go mouldy, and surely must rot if wet, otherwise why add it to compost heaps.

Anyway, it's surely pointless as no one would use it underground , period..... would they.. :cry: ?

Once above ground, you could go up with bales, and what a thermally efficient home that would be ..

Hay is stock feed much more valuable for that. :)

Straw needs to "breath" otherwise points like mouldy will occur :cry:

I would wonder, the earth temp is very stable in temperate areas, normally only varies by about 2 degrees year round at about a metre. Good insulation on the ceiling/roof is where it's needed really. Space UG is at premium throwing it away in lots of insulation would add up to a lot of pennies or additional cost.

I know this is a fairly old thread but nearly all the big old homesteads built around the turn of the century (before last) had cellars almost as the original poster has suggested he'd like except they just used redgum logs for the walls.
Many shops also had them and many are still there but covered over.
