Have you ever seen homes such as these? The Higaonon of the Northern Mindanao have a residential complex intricately designed on trees: The Higaonon Tree House. The structure essentially combines several smaller spaces together through catwalks.
Located in some hinterlands of Agusan and Misamis Oriental, the house is characterized by a lashed sapling, nipa or cogon grass, split bamboo, rattan, and tree bark. The Higaonon Tree House is designed in such as way that the roof thatchings also serve as the structure’s walls. Catwalks of about 6 feet and 8 feet wide connect smaller houses together that make a central communal space.
These tree houses can serve about 60 people.
