The weekend Chron ran an interesting article about residential cave-building in Napa.
[Caves make] aesthetic as well as economic sense. A bare-bones cave can be built for about one-third the square-foot price of a wood-framed addition. And, when construction is finished, the land appears untouched.
So now I’m having visions of a subterranean recording studio. I’d miss having a view, but installing windows is the worst thing you can do to a soundproof wall. Then again, the echoes in a round stone room would be ferocious. Hmm, there would be trade-offs. I suppose if I end up wood-framing a square room inside the cave, I haven’t really saved any money on the construction.
