Irregularly placed square openings puncture the thick concrete exterior of SV House in Portugal, recently completed by architecture studio Spaceworkers.
Located on a sloping site near the town of Sobrado, the blocky, three-storey home occupies a plot once occupied by the home of the client's grandfather.
It is formed from board-marked concrete, designed by Spaceworkers to "stand out" but also present a "quiet silence" to the street, while the square openings are positioned to frame outward views while maintaining privacy.
Spaceworkers has used deep concrete reveals to frame views from SV House 
"Openings for the different spaces go beyond the mere need for ventilation and natural ventilation," explained Spaceworkers. "From the outside, they are an important element in the composition of the elevations and in the perception of the occupation of the house, but without revealing too much," the studio said.
"Internally, these openings focus on framing pieces of the distant landscape, or even the sky, avoiding the surroundings punctuated by houses."
Board-marked concrete has been used to form the home
Due to the sloping site, the entrance to SV House sits off the street at first-floor level, with a ramped driveway leading to a garage on the ground floor.
While only two openings overlook the street, to the south of the home are sliding doors that connect a double-height living area to a private garden.
