A small two-story residential house originally on the west side of the city of São Paulo was bought to be transformed into an atelier or an office, with independent access to each floor. As the grounds have hardly more than 150 m², architects Paula Zemel and Eduardo Chalabi, made decisions along the line of opening free areas. To gain space on the upstairs and downstairs floors, all of the interior walls were removed and uniform flooring was achieved with a granilite coating.
The need of support furnishing was resolved with the highlighting architectonic element of the house: a large structural bookcase made of exposed concrete, which takes up a good part of the side gable and rises from the floor to the roof.
Since the house is made of structural masonry, this element helps sustain the gable itself, the upstairs floor slab and the roofing timbers – each concrete riser works as a pillar, which all point towards a metal band. The roof was also a target for alterations: the slab above the upstairs floor was removed and the trusses were restored to remain exposed. Since the four gables of the roof were transformed into two, the almost archetypical western design of the house predominates.
Complementing programmed necessities are independent restrooms and break rooms, resolved with the construction of a concrete tower, at the back side of the property. The construction even comes with two outdoors areas, one in front, lined with concrete block paving and another out back, covered with stone gravel and reserved for lunches or informal gatherings.
