The intervention aims at multiplying the possibilities of use of the attic space, as well as incorporating the rooftop as an outdoor extension through three main actions. 1. Reuse: the existing as much as possible in order to make the most of what is already there. 2. Remove: some of the existing partition walls and substitute them for an openable box made of sliding walnut wood veneer panels to improve the flexibility of the space 3. Add: a new staircase that provides natural light and ventilation through an opening on the top and a perfectible pavilion on the rooftop terrace for parties.
