Yes they are very expensive! This one, which is huge and set partially into the earth on the north side, is around $20,000! Guaranteed 100 years they say, although none of them will be around to make good on that if any problems arise. I keep thinking "what if they decide to move it?"! Apparently this client is already a bit sorry they made it so big. They have some sort of wax on the windows that are thermostats, so the greenhouses regulate their own temperatures without power of any kind. Pretty cool stuff.
