SFJ 6—102 social housing in Madrid,
design: Marmolbravo
The SFJ 6 project by Spanish studio Marmolbravo is an example of a modern approach to social housing, in which architecture plays a key role in shaping the urban fabric and improving the quality of life for residents. It includes 102 apartments that have been designed to integrate with the surrounding infrastructure, responding to urban challenges such as the diversity of development, the topography of the site and the need to create new public spaces. With its complex massing, the building not only harmonizes with neighboring structures, but also enriches the urban space with new, lively gathering places. Particular attention was paid to adapting the first floor to the terrain, which increases the points of contact with the city, creating a more friendly and functional environment for residents.

integration with existing buildings and natural ventilation methods
The complex form of the facades, the changing heights and the setback of the top two floors introduce urban diversity.

In addition, the perceived scale of the building has been reduced by unifying the window openings, which appear larger than they actually are, giving the building a more welcoming feel. The building ranges from 5 to 8 stories and includes 4 courtyards, which are adjacent to the courtyards of adjacent buildings. The decision for this design solution allows for the creation of large internal courtyards that double in size, connecting to the courtyards of adjacent buildings. Each courtyard is an independent space with a separate entrance from the outside and its own vertical transportation hub, although they are all connected at the parking level.

passive strategies—cross ventilation
Each courtyard has its own unique atmosphere, which is highlighted by the ochre colors of the facade contrasted with the lush vegetation planned as part of the project, which promotes a microclimate in the city center. The layout of the apartments was designed to provide cross ventilation and street views from the living area. Commercial spaces have been provided on the first floor, at both ends of the building, to improve the urban conditions of the surrounding area, bringing commerce and thus activity into the public spaces.

role of social housing in shaping cities
The project includes new public spaces, such as a new pedestrian street and a terraced plaza on the south side of the building. The building has two to three underground levels for parking spaces, lit by natural light through large openings leading to the courtyards. The project envisions a low-energy building. Reduction in energy demand is achieved through passive strategies such as cross-ventilation and high-performance thermal insulation.

a low-energy building of energy class A
In addition, heat recovery systems and ECOBARRIO district heating supply for hot water and heating, supported by active systems, were used. Finally, as part of the use of renewable energy sources, aerothermal systems supported by photovoltaic panels were installed, allowing the entire building to achieve an A-energy rating.

social housing in city centers—urban and social challenges
Social housing in Spain and Poland plays a key role in shaping modern cities while addressing diverse social, environmental and economic needs. Examples of innovative projects, such as SFJ 6's social housing, show how an integrated urban approach that includes revitalization of existing buildings, sustainable technologies and aesthetic and inclusive solutionscan not only improve the quality of life for residents, but also strengthen local communities. In the face of challenges such as climate change, an aging population and gentrification, housing policy must constantly evolve to ensure universal access to dignified and welcoming spaces, which is the foundation for long-term development in both Poland and Spain.
