架构师提供的文本描述。在阿尔坎塔拉污水处理厂的现代化项目中，由于一些环保原因，形成了一个绿色屋顶。此外，该计划还设想了两座服务大楼：一座用于监视工厂，另一座用于为上市公司总部提供住房。

在这个项目中，不同的项目重叠：工厂覆盖着一个“厚厚的可居住屋顶”，里面有设施、走廊和其他服务。在领土范围内，绿色屋顶延伸了阿尔坎塔拉山谷的天然山丘，减少了道路基础设施对该地区造成的破坏。

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.

在屋顶内，这座建筑融合了自己。通过形成地形，形成适宜居住的条件。行政区域由一个限制墙、一个玻璃平面和具有次要功能的分散空间组成；这些要素将内部走廊与工作空间分隔开来。

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.
