In a three-story factory converted into apartments/offices during the 1990s in the Colegiales neighborhood, the task arose to transform a unit that used to function as an office into a home. The unit consisted of two floors without divisions and a disused terrace due to the shape of its structure, a curved concrete slab that did not allow for the use of the upper floor. Access to it was through a hatch door that separated the unit from this exterior terrace.
