S. Victor Studios | A2OFFICE | International Residential Architecture Awards 2021

A2OFFICE: Winner of International Residential Architecture Awards 2021. This intervention consisted in the rehabilitation of an empty building originally built at the end of the 19th century, located in the street of São Victor, in the city of Porto. It is a building that is situated just at the entrance of the street, assuming an introductory role of it.

The building has an unusual planimetry, in the shape of a triangle, with a deployment of only 52sqm and has only one façade. These factors were the main conditioners of the whole project and are the main distinctive element of this building in front of its peers, leading to an equally unique architectural solution that sought to take full advantage of these constraints.

The original structure of the floors, in old wooden beams, was in good conditions, so they were maintained and reinforced. The structure of the roof was also maintained and reinforced, although the roofing tiles and gutters were completely redone, as well as the thermal insulation and interior finishings.

A new staircase, also made of wood, appears in the place of the original staircase which, due to its small size and poor structural condition, was demolished. This staircase assumes a scenic role along with the triple height in the corner of the building, on which the intermediate platforms lie. Nevertheless, the design of the staircase derives essentially from the greater need to overcome the heights between floors in the smallest possible space, releasing the core of the plan to the apartments area.

The apartments of the ground floor, 1st floor and 2nd floor have a similar layout: as the area is considerable small it was decided to diminish the partitions to the minimum, so one just have walls for the bathrooms. In the upper floor, as the space needed for the staircase is smaller, one could organize the apartment layout in a different way, although the premise of few walls was maintained. In the corner of this apartment, a small terrace brings some newness and punctuates the entire intervention.

In this intervention, besides the volumetry, the original colours of the facade were restored with the aim of transmitting an historical continuity.
