GreenHouse / OTTOTTO

When OTTOTTO studio removed the plaster from the walls of this house, two imposing stone walls were revealed. Their beauty made it inevitable to keep them in sight, adding just a new layer, in metallic mesh, to blend the 20th century with the new structure and skylight. As it is common in the center of Porto, Portugal, the house is narrow, long and has only two fronts: the challenge was to bring more light to the semi-basement and to all the interior spaces; drawing a single cut in the roof was the solution - a "square ring", with a constant width of 70 cm, that crosses the three floors and is overlooked by eight windows.
