Text description provided by the architects. In Alcantara Wastewater Treatment Plant’s modernization project, some environmental preservation reasons imposed the creation of a green roof. Furthermore, the program foresaw two service buildings: one for monitoring the Plant, and a second one to house the public company headquarter.

In this project, the different programs overlap: the plant is covered with a “thick habitable roof” which houses the facilities, corridors and other services. In a territorial scale, the green roof extends the natural hills of Alcantara Valley, reducing the damage the road infrastructures cause to the area.

Within the roof the building integrates itself. By shaping the topography, habitability conditions are generated. The administrative areas are defined by a limiting wall, a glass plane and scattered volumes with secondary functions; those elements separate the internal corridors from the workspaces.
