I could renovate the guest room downstairs into a bedroom and nursery. It'd be big enough it was originally a second reception room anyway. And you could have that like Pierre and Matthew have the basement. And then Tamm's room upstairs could be the guest room or someone else could move in. Whatever works.
If you don't want it or you don't want to think about it, that's cool. The offer will stand as long as you want it to stand.
