Architecture must serve its society. Inclusion is the most important feature a building might have, and performance is the value that should be used to make architectural decisions.I began this project understanding which relation today’s society have with built spaces. Different families, times, jobs deserve different spaces. Mixing tipologies open a new possibility to unplanned activities and events, liveability of spaces, interaction and in the end, quality of life. Patio houses, small and medium apartments and row-houses are planned with offices, shops and cultural spaces, generating new qualities to the urban landscape. In relation to the site, the building opens up to the surroundings connecting the street with a roof-garden semi-public, creating an elevated ground floor that contributes to the flow of people. The openings follow a strict rule based on constructibility and modularity, but also the amount of sun reaching the envelope, this way taking advantage of natural light and heating, reducing the need for active systems. Also, because of the various programs, is possible to save energy and heat generate from some spaces (shops, offices, common kitchen) and use it were it is needed (housing). The shape of the building follow the plan from the city but adapts itself to the context - a double curved roof taking advantage of the sun and avoiding the shadow created by the neighboors. All the materials were planned to be as natural and renewable as possible, using mainly wood for the envelope and wall structure, with concrete being responsible for the primary structural system and slabs - for thermal mass. Glass areas were planned according to the incident sun and insulation being made of sheep wool or polyurethane upcycled from old fridges. Sustainability is achieved in different scales and meanings, but never forgeting that the building must be first of all, great architecture for the people and the city.
