Four buildings –each one oriented to one of the cardinal points- define the space on the top of the hill of Mount Gaiás, an enormous plaza in urban terms, though simply an extensive plane in the context of the surrounding landscape. The buildings mark the space instead of limiting it, the elements that define it are in the topography, the view to the West facing the city and the view to the East facing the landscape, created by gardens and small parks.

The buildings are simplified cubes, moulded specifically by their different functions and their position on the terrain. They share the fact that they are all rectangular volumes, they all contain patios and they are built of stone.
The structures are built in layers of stone placed in rows. Several types of stone are used, local stone and imported stone, in some cases isolated, or perhaps in a more contemporary fashion, placed in rows using concrete mixed with fine sand, coarse sand and coloured sand, in alternate layers.

In principle, the agricultural landscape would be preserved in general terms. Considering the possibility that the agricultural use might come to be discontinued in the future, a flexible concept would be developed with elements implanted as gardens and parks. An so, the subdivision in plots of the agricultural landscape could act as the structural basis for any future landscape or gardening interventions.
