Urban heat is one of the preeminent crises in recent years. In spite of being conscious to live compatible with the environment, at times we fail to achieve that. And we humans are the ones who eradicate natural resources, as well as defend them. Still, we are at the mid-level in experimenting with designs and techniques to protect our Glob. Paris-based Architect Vincent Callebaut designed a condominium tower that surmounts all the bioclimate experiments that are accomplished so far. The rainbow tree tower in Cebu, Philippines is titled after an iconic tree of the Philippines “Eucalyptus Deglupta” which is also commonly called “The rainbow tree”. This 115m high tower slams down the record of tallest timber tower Majestarnet, Norway.

Each timber module measures 4m on both sides and the height varying from 3.2m to 4.8m. However, the structure will build by superimposing the timber rods and connecting them all with organic adhesives.
