As I promised in here there is my castle for comparison. Location: near oasis north from Sepermeru. All walls and central keep are made from triangular foundations and floors. Walls are guarded by archers and reinforced with palisades and fences. Behind the walls are swordsmen, horse stables, altars and animal pens. Central keep is built on top of cliff (also triangular floors, for sake of uniformity) and contains spare beds for clanmates, craft stations and armory.
Some square foundations are used for horse stables for reasons of project now abandoned.
ps My horse named 52/70 not because it is 52nd of 70 horses, it’s a stats leveling chances. )
other shelter is built by clanmate before she joined with main clan - a treehouse near south Sepermeru. Three bedrooms, kitchen and hundreds of chests - all in one small treehouse.
