Also, the white panels in the brown room on the second story are placeholders for paintings (to be stolen of course), and the room dividers are actually arches. I imagine if this building were to be pitched, it could possibly appeal to boys and girls like this: have the "boy" side stress things like thievery and breaking and entering; and the "girl" side general princess-y stuff like ballroom dancing, dress up, tea parties (something I'd actually like to see!), etc. I'd take it even further by emphasizing the modular aspect, by selling add-ons and rooms with different purposes to appeal to both sides. Like maybe a ballroom is sold with one room add-on, and a war room or whatever is sold in another room add-on. Towers, a dungeon, a pavillion, an armed gate, a scullery, there are many different routes to take. And the best part is, it's up to the child of what goes in or out the castle!
Any suggestions/improvements to be made on this castle/palace are fully welcomed!
