Aut cum scuto aut in scuto
Looks nice, but far more house than I'd need. I'm more of a small-cabin-in-the-woods kind of guy.
Underground electric service?The rolled pool insulation indicates the possibility of a heated pool.
I think it is probably a solar cover, similar to bubble wrap but much thicker, allows the sun's rays to penetrate and heat the water and traps the heat in. We had one on our pool years ago, worked quite well.
Mikey is correct about the cover, Now if the largest part of the building is a garage then...YES.
On the side of the hill facing the sun, the side you can't see in the pik, is a large solar array providing jooce for the crib. The 40,000 gallon pool acts as a cistern for the rainwater reclamation that is used in the crib.
