Build a large, symmetrical castle-bridge with a tall central hub and two long wings. The main floor has a central entrance hall, with side rooms branching evenly left and right and access to both wings. The second floor mirrors the layout, with a central room above the entrance and evenly spaced side rooms extending into each wing. The third floor repeats this symmetry but with slightly larger central space and smaller side chambers. The top floor is more compact, with a central room and a few surrounding rooms plus balcony access. The left and right wings each follow a linear pattern of connected rooms and corridors, evenly spaced. Below, add a basement with multiple connected rooms centered under the main hall, and extend smaller hidden rooms beneath the wings and bridge.
