Thought I'd answer, since you never got a reply. Bee houses are where the bees put their larvae (babies) to grow up. Solitary bees don't live in houses like social bees live in hives, they just live out and about. They don't mind the weather, or they'd sit somewhere more protected.
A related fact: birds don't live in nests. Some birds make nests for their babies, but all parties leave the nest once the babies are grown. They just sleep perched in trees.
