BRIEF DESCRIPTION OF THE PROJECT
A building with eight apaprtments and community spaces in a co-housing system. The building is conceived from the interpretation of the landscape of the Barceloneta neighborhood, with the characteristic typology of the windows and the solar protection, also very Mediterranean. At the same time, the singularity of having three facades is considered, with an special attention to the two corners, where the building opens up in a determined way.
The domestic space is the all building, the home of all the members of the cooperative. There are the private spaces, the apartaments, and the community spaces on the ground floor, through a space for socialization, extension of the neighborhood, work and meeting, and the deck, completely accessible, whith the laundry, the facilities spaces and the garden.
Solving them with the maximum perimeter of the facade, eight apartments of three different typologies are proposed, adapted to the needs of the family units of the members of the cooperative, and adaptable to future changes in them. In each of them, the permanent location of the wet ant technical spaces makes it easy to modify the distribution, expand or reduce the number of rooms.
The building search the maximum energy efficiency, the building is conceived from an important commitment to environmental sustainability: for this reason, it is resolved with a mixed, metal structure with collaborative CLT laminated wood ceilings. The thermal inertia is achieved with the introduction of brick for the perimeter enclosures, a solution that allows the floor to be solved using a dry solution.
The CLT wood, the metal structure and the brick are seen, making the material sincerity a differentiating feature of the building’s character.
