Krorral
this form of architecture was developed by the Gkrur clan of Wookiees on the planet Kashyyyk, and was later reused by the Wookiees on the Alaris colony. The Krorral architecture emphasized an integration of the building with its environment, especially in rainy environments where a flat-roofed structure would encounter problems with excessive water. The Krorral form used domes and sweeping cones for the roofs of buildings, which forced the rainwater downward and off the roof without any standing pools.
