In pre-Hispanic Philippines, Filipinos built large wooden residences for the ancient nobility and royalty (such as Lakans, Wangs, rajahs and datus) called "Torogan" or "Bahay Lakan" ("king's house").The windows of torogan are slits and richly framed in wood panels with okir designs located in front of the house. The communal kitchen is half a meter lower than the main house is both used for cooking and eating. The distinct high gable roof of the torogan, thin at the apex and gracefully flaring out to the eaves, sits on a huge structures enclosed by slabs of timber and lifted more than two meters above the ground by a huge trunk of a tree that was set on a rock. The end floor beams lengthen as panolongs the seemed to lift up the whole house. The torogan is suffused with decorations. There were diongal at the apex of the roof, also an intricately carved tinai a walai, okir designs in the floor, on windows and on panolongs.
