Krorral was a form of architecture developed by the Gkrur clan on Kashyyyk. This style was later used by the Wookiees on the Alaris colony. It emphasized the usage of integration of a building with its environment and was particularly suited towards raining environments where a flat-roofed structure would encounter problems with excess water. Krorral architecture used domes and sweeping cones for the roofs of buildings thus forcing rainwater downwards and off the roof without any standing pools being formed.
