Not so much a $20 million Malibu mansion as a lovely hillside home in the Shire.  But the concept’s the same… roughly. Ok, I’ll admit I’m stretching the association a bit. This house in Wales is slightly less, shall we say, ostentatious than a multi-million-dollar mansion.  For about $6000, if my pound-to-dollar conversion skills are at all accurate–not even a 30,000th of Miss Roberts’ cost–this “low impact home” built into the side of a hill uses straw bales throughout for insulation purposes, as well as a woodburner for extra heat. Underground air is used to cool the fridge. Solar panels provide the light, and there’s even a compost toilet, and so much more. And you get to feel like you live in a fantasy novel, at no extra cost.
