Well, that's not as crazy as it sounds...If we ever come into a large sum of money, my DH has often said that we would attach a sun room or GH to the south end of the house. That means we would need to knock out the wall...so?
BTW, I have ordered from Hausermann's before and am waiting for a shipment now. Their packaging is great even in colder weather,and the disclaimer at the beginning of the ordering process says that they will hold up your order if weather is severe. But surely you have growers closer to you?? Anyway, their prices are a little high, but I do love to look at their on-line catalogue.
You're starting out great
Happy growing...
