ELIGE MADERA Disruptive Projects in Concrete Cities A warm and natural building in the middle of the so-called "concrete jungle" – this is the challenge for the city of Toronto proposed by Penda. A warm and natural building in the middle of the so-called "concrete jungle" – this is the challenge for the city of Toronto proposed by Penda. Toronto Tree Tower, a project in the Canadian city proposed by the architectural firm Penda, promises an 18-story cross-laminated timber (CLT) structure, lined with trees and plants. At 62 meters high, the unique skyscraper proposes a facade that enhances the aesthetics of the city. As Penda partner Chris Precht tells the architecture site dezeen.com, "our cities are an assembly of steel, concrete and glass," but "if you walk through the city and suddenly see a tower made of wood and plants, it will create an interesting contrast." The tower is intended to be an example of sustainable construction in the urban landscape, using CLT as a raw material. For the project, the CLT panels will arrive pre-assembled, to be installed directly on the building's foundations; a method that, in addition to being faster and quieter, generates less waste and is more respectful of neighbors and the environment.
