Perhaps I should just go back to using the term "solarium", or if that's too highfalutin, just "sunroom". Ursula has a similar structure as I, but hers is much more of a greenhouse, built for growing and propagating plants rather than for human inhabitation. I think that's right but
@Ursula can correct me if I err. I my mind, and I'm no architect, a sunroom will have a solid roof but a solarium will have a glass roof. Again, for those in the business of building such things, correct me if I'm wrong. Our new space has glass walls and a glass ceiling, at least a glass ceiling over half of the structure. But it is as much a living space as a greenhouse space. If anyone has a better term than "solarium", please drop it on me. I am all eyes and ears.
