'House in Polônia Street' by Gabriel Kogan + Guilherme Pianca


São Paulo, Brazil (BR)
Viewed from nodal points, the architecture of this house engages the site’s geometry and rhythm. From the entrance, one perceives a deliberate moment: a stretch of garden that runs nearly the full depth of the 42 m by 15 m lot, leading the visitor forward while the house sits parallel to the left side of the garden. This external view of the home at the threshold of the site was conceived as a key nodal point of spatial perception.

From there, the sequence of the journey through the house unfolds through framed views that emphasize frontality and depth, minimizing diagonals. The grid used for the design informs the composition: concrete modules of 2.90 m width by 3.00 m height repeat orthogonally along almost the full length of the terrain over two floors. The home was imagined as a prototype that could extend across the landscape. Solid end façades mark abrupt terminations of that continuity and hint at its possible extension.

Finishes become structuring elements rather than superficial layers. Opposed to trends of ornamental “one-upmanship” in interiors, this house embodies a convergence of function, material, and finish. The wood panels serve as doors or built-in shelves; the cementitious floor is simply the floor; the glazing is the window and so forth. Even in kitchens and bathrooms, material choices were made for durability, ease of maintenance, and authenticity—avoiding arbitrary decoration.

Seating in the living room offers a surprising connection: when you sit on the sofa you eye the garden at the same level as the exterior ground. The lowered floor level gives a 0.55 m taller ceiling height in the social zone—creating a sense of expansiveness without breaking the external module dimensions nor turning the home into a “tall box.” Thus the horizontal proportions of the overall composition and the square modular façade remain intact.

The ceiling in the living room is left “without anything”: the wooden board ceiling is uninterrupted by lights or diffusers, lending an atmosphere of purity and reliance on indirect, reflected lighting. The air conditioning supply is embedded in the floor; the return runs in a recess adjacent to the window frame. The living room becomes a pure wooden box nested in a concrete grid.

Facing that interior wood pavilion is the garden, designed by Rodrigo Oliveira, with raw stone paths and tropical plantings. From inside, the greenery seems to travel inward—a contemplative journey from outside to within. The concrete structure establishes a tension and harmony with the garden: the house is not simply placed within nature but enveloped by it. The garden becomes a controlled envelope—a sort of architectural promenade—that enables carefully composed perspectives.

This project draws from multiple architectural traditions: Japanese minimalism, British restraint, Swiss precision, Portuguese textural subtlety, and Brazilian modernism. It represents a kind of convergence of schools—something the new generation of architects in Brazil, including this office, is exploring.

Above the visible dual vertical concrete grid of the façade lies a recessed additional floor, carefully set so that it cannot be seen from the garden. The goal was to preserve the strong horizontal grid of the façade and not let this additional level disrupt the composition, while still meeting the client’s program.

Interestingly, the first versions of the project were conceived in timber structure, but at the client’s request the final execution used concrete. Yet the logic of the earlier timber concept remains: exposed columns that appear independent were carried over into the concrete version.

A carefully calibrated material palette was established during design development. The façade concrete was tinted with a small quantity of pigment to yield a warmer tone. From that base, the palette shifted toward a red-leaning atmosphere, contrasting with the surrounding deep green. Numerous onsite prototypes were built to understand how the materials would behave in place, refining the tones and articulation of details.
