Guild hall

Stone floors imply paver over earth (or concrete).
Wood floors imply that there is an air space below (like a second floor or over a crawl space).
You use both on the same level ... so does half your building have a crawl space or basement and the other half not?

Wall to wall carpet is fairly modern (the large patterned floor looks like carpet). Area rugs historically more common.

There is a basement under the building. While your assumptions are logical, I have been in a number of old mansions that had mixtures of wood and marble flooring on the same floor, with and without basements or other floors under them. With enough money the owner can get it build anyway he wants, as in the stone staircase on wood floor that needed special supports you mentioned in another post. It wasn't practical, or in the original blueprints, but the rich athlete got what he wanted. These guys have a vault full of treasure, and magic, they can have their floors made to order.

The large game room has a marble floor, the only wall to wall rug is the hallway with the stairs. Perhaps a bit modern, but it is an older looking pattern, and it is a fantasy realm, who knows what the fashion is in that time and place. It's not like it is an impossibly advanced technology, and it was not supposed to represent any specific time frame on Earth.

In the southernmost room, isn't it a bit odd that the sun is shining through three windows each on different sides, but coming through at the same straight angles? So basically you have three different external light sources?
