Vincent Callebaut Architectures has imagined The Rainbow Tree, a modular mass timber condominium tower in Cebu City, Philippines. The building is a 32-story, 115-meter high tower built of solid wood. Inspired by traditional "Bahay Kubo" homes, the modular mass timber tower stacks 1,200 prefabricated modules, each with sides measuring 4 meters and a height varying between 3.2 to 4.8 meters.
