Gated suburbs in Tigre, north of Buenos Aires, follow a familiar formula: a lot on a curving cul-de-sac, a house that presents a polite face to the street, and a back garden facing water. AtelierM, led by Matias Mosquera, starts GP House from the same conditions. The 320 m² house sits on a corner where the street bends, and the rear of the lot opens onto a lagoon. The studio's response is to treat those two curves, the urban one and the natural one, as the forces that shape the building.

The result is a house that stays closed toward the corner and opens step by step toward the water. Its most interesting feature is the roof. AtelierM did not cap the plan with a flat lid. The roof rises as a continuous planted surface that you can climb, and it loops around an oval courtyard with a pond at its centre. With landscape architect Carolina Pell and structural engineer Marcelo Mastropietro, the studio has turned a suburban house into a small piece of topography.

A Closed Face to the Corner

From the street the house reads mostly as wall. A single sweep of concrete follows the bend of the corner and dips over a dark timber garage door. It slopes upward instead of standing as a vertical fence. Seen at street level with a passerby pushing a stroller, it has the scale of an embankment more than a facade.

We think the restraint is the right call. Corner lots are exposed on two sides, and most houses respond with hedges or high fences after the fact. Here the building itself provides the privacy. In low evening light the board-marked surface turns orange, and the only interruptions are a thin steel railing and the green fringe of the roof garden. The house gives the neighbourhood a calm, continuous edge without seeming defensive.
