Description of the project: 

Once modern society standards have been reached , there is a real need in developing new quality levels, including space, constructive materials and the way housing can improve. These new standards are not only demanded by industry or clients, but also normative. For us, being able of generating accurate proposals for new social challenges is a priority way of approaching our aims. This project is an exploration of the day-to-day social evolution and the new family typologies.

In this case, the project has been built in a new area in Getafe (Madrid), where there isn’t any kind of local identity. The way we treat this situation is as an urban opportunity, trying to create a city and a contemporary cultural environment.

We propose a group of high quality living spaces, with exterior spaces in all cases. The way these exterior spaces are combined responds to the urbanistic regulations, using different orientations in order to accomplish diverse exterior spaces. The typology is a hybrid between an open and a closed block, leading the ground floor to have a better relationship with the urban environment and the south street.

This design reinterpreted  traditional and popular architecture as a tool to create a new identity for this area, such as terraces, patios, and local vegetation as a way of sustainability and low-cost maintenance. The result is an effective urban set that can be adapted to different urban sensibilities.


The project uses the possibilities the urban planning allows, maintaining a 12 meters depth in all the building through the plot. The building shows 1 meter cantilevers from first floor, with a total width depending on normative.  Once the building gets taller, the movement and vibration is created in the façade thanks to volume subtractions. The building expresses itself from the outside through these voids to be seen from the landscape. In this way, the voids  connect the exterior urban environment with the interior plot, maximizing sun in the plot common spaces. The windows have mainly a horizontal design, excluding exterior terraces doors. The medium height volumes’ roofs are used as terraces for the tallest volumes, with different ways of reaching them: directly from the apartment or using stairs.


The housing units are developed depending on the boundary conditions. Each unit is organized around a generous living-room that connects with the exterior views. The terrace is placed depending on the orientation. This housing unit concatenate spaces with the same privacy level, so that the private circulation is always continuous. The circulation between different rooms is minimized.

All apartments have two facades, making the housing units connect one orientation with another and so the ventilation. Each core  gives access to 2 units, except for the corner ones.

The typologies inside the building are flexible and designed in order to change though time and day-night. This approach gives the user the capability to exchange rooms as desired. The housing unit is understood as a potential volume  and the evolutive possibility has been made from the beginning of the project.

The plot main entrance is made through a pedestrian street, before the building arcade. Those open arcades connect the building interior with the public common spaces in the exterior, so that the cores  are design as quality and dignified spaces. This idea is inspired by the traditional quarters in Madrid and it has been included in the project in contemporary key.

The whole set is developed as an equipped atmosphere for the contemporary urban life. The interior square common spaces are designed as a fragment from the outside landscape, being manipulated and captured. The pavement changes to guide people through the plot, and it transforms into different materials depending on the use. Trees and vegetation complete this interior environment, always choosing local species to make the set even more sustainable.
