Linazasoro & Sánchez creates a residential building as a robust, highly compact volume that connects directly with the exterior and avoids creating multiple interiors, thus fostering the relationship between the volume and its inhabitants with their context.
To maximize the living space, a succession of cores is created, connecting two apartments per floor. This avoids a central gallery layout and restricts the dialogue between residential units to the shared lower floor, thus fostering freedom of movement.

Project description by Linazasoro & Sánchez
The development is located in Villa de Vallecas, within the APE 18.05 La Rosilla. It has a maximum buildable area of 6,500 m² for residential use. The maximum depth is 12 m, and regulations allow a maximum height of ground floor + 7 (VIII) on the western end of the plot, and ground floor + 4 (V) on the eastern side. All these conditions are fully utilized in the development.
The project presents a simple overall volumetric design of an orthogonal block with a clear objective of rationality, ease of construction, and construction economy.
As required by regulations, two distinct bodies have been designed: a tower to the west of ground floor + 7, and a longitudinal block to the east of ground floor + 4, distributed in a "T" shape and connected at ground level.

The building was designed based on the following premises:
- All apartments must have cross ventilation, which is mandatory for 3D and 4D apartments according to the EMVS NRP, and highly recommended for 2D apartments. In the block, all apartments have two facing facades that allow for direct cross ventilation. In the tower, there are also two facades, in this case perpendicular, with 90° cross ventilation.
- Avoid interior courtyards; the complex does not have interior courtyards; instead, all ventilation and lighting are provided directly to the exterior.
- Avoid central gallery layouts with apartments on both sides, due to the excessive use of surface area for common areas. All apartments are through-plan, and each core communicates with two apartments per floor.
