There's one not far from here that is just gorgeous!!
It snuggles right in between two rock faces and the way they built it,, the front wall of windows and darker stone header, matched the strata of the rock face that was on both sides It blended in great, south facing,very nicely built,(I'd been inside before) nice natural rock interior walls and central fireplace, Huge patio off the full windowed front, small spring feed stream running just down the hill a hundred feet or so away, close enough to hear the water anyhow,a super view down this little valley over looking a real small, old VT 10 house township, and other mountains in the background, totally off grid but with all the normal electrical stuff any other house has,, it's just beautiful. No bills,,just tax's. It's a friend, of a friend of a friends kinda thing,,, property He built it himself with a old $300 small JD dozier with a back hoe and and well used excavator for $1000. His total cost was <30K if I remember right in turn key complete condition,,hell I gather he's been there about 35 years and has done upgrades, and obviously added panels. He heated and ran the whole place completely with 2 cords of wood and ran a gas stove and lights on one of those pregnant looking upright tanks,,150gal???? And that was it for the whole year and with the natural sun coming through it was warm as toast in the winter!!! It's Amassing
I'd seen some pics before of others in different places and some are very impressive!
I'm way to old and bunged up to tackle something like that now, but it had been a consideration at one point, life has a way of changing the best laid plans sometimes.
