Assuming the recently unveiled Rainbow Tree by Vincent Callebaut Architectures is actually built, the greenery-covered timber tower will rise to an impressive height of 115 m (377 ft) in Cebu, Philippines.
The project will also feature significant sustainable design, including solar panels and wind turbines.According to Vincent Callebaut Architects, the Rainbow Tree will be built from a total of 1,200 prefabricated CLT (cross-laminated timber) modules. The firm makes no mention of a concrete core, so assuming there isn’t one, it would smash the current all-timber tower record of 81 m (265 ft) held by Mjøstårnet, in Norway.
The tower’s design will be defined by its sculpted wooden balconies, which will integrate planters to hold a total of over 30,000 plants, shrubs, and tropical trees. Shou Sugi Ban-treated wood is planned for the cladding, which is the traditional Japanese technique of charring the wood to protect it from insects, as well as offering improved durability and a distinctive appearance.
