The conception of an apartment building in Cerdà’s Eixample in Barcelona 150 years after the implementation of the famous “Plan Cerdà” induces a reflection on how to conceive the project and specifically the facades in a way that responds to the necessities of the 21st century while maintaining a dialogue and respect for the years of history.

The traditional elements as the balcony, the blinds, the cornices and the colours are reinterpreted here in a way that not only integrates into the built environment, but does so in a way that incorporates both passive and active energy saving solutions.

The building program is made up of 27 apartments and two commercial spaces with attics that look out over Casp Street. The typical floor houses 5 one and two bedroom apartments. The top floor houses two apartments with two bedrooms and two one-bedroom apartments, while the ground floor is made up of three duplex apartments, each with a garden, distributed on the back side of the building looking out over the patio in the block's interior. 2 floors underground provide garage space for 34 vehicles.

The street facade is composed as a dialogue between fixed panels formed by steel framed vertical ceramic planks, and sliding aluminium blinds providing the necessary privacy and lighting control. Simultaneously the solution meets with the strict regulations of the Eixample area. The block's patio facade is formed by a steel reticle that limits the broad windows of the apartments. Solar protection and privacy are provided here by folding aluminium blinds that serve to create a dynamic and changing façade. On the roof of the building solar panels are installed and connected to the heating system of the building in order to reduce energy use of the hot water production. The principal building materials (blinds, ceramic elements, and aluminium window frames) are recyclable. The flat roof is made using a special EPDM sheet and finished with lightweight concrete tiles, material that allows recycling and reuse.
