Felipe Caboclo Arquitetura Lays a Timber-Roofed House Along the Contours of a Porto Feliz Hillside

Flow House, or Casa Flow, is a 1,530 m² single-family residence in Porto Feliz, in the interior of São Paulo state, completed in 2025 by Felipe Caboclo Arquitetura. The stated ambition is a "free, fluid" architecture in constant dialogue with the landscape, one that refuses to dictate a way of living so the people inside can shape their own routines. Plenty of houses make that claim. Fewer of them back it up with a plan and a section that actually let go.

What makes this one worth your attention is how much it relies on very few moves. The house follows the natural contours of its site instead of flattening them. It pairs heavy board-formed concrete with a thin, low timber roof. It uses circulation, not rooms, as the main experience. The result is a large house that rarely reads as large, because it keeps pointing your eye away from itself and toward the horizon.

A Long Roof Laid Along the Contour

Seen from the lawn below, the house is essentially one horizontal gesture: a long timber-edged roof floating over a raised terrace, with a stair and an infinity pool marking the change in level. The building does not climb the slope. It settles into it, letting the grass run right up to the base so the terrace reads as a ledge in the landscape rather than a podium above it.

The side elevation shows how disciplined that roof is. A board-marked concrete wall carries the weight visually, and the timber roof sits on top as a thin plane, almost a sheet. That contrast between mass and lid is the house's main tectonic idea, and it is repeated often enough that the whole 1,530 m² hangs together as a single object.

Concrete and Timber After Dark

The dusk images show a more layered house than the daytime overview suggests. The upper volume combines banded concrete with rust-toned cladding and a single lit strip window, seen through branches. The concrete picks up the texture of its formwork boards, so even the heaviest walls carry the grain of timber. That is a smart way to make two materials feel like relatives instead of opponents.

The approach up pale stone steps, threaded through groundcover and tropical planting with low uplights, tells you how much weight the landscaping by Cenário carries here. Lighting by Lightworks stays low and indirect, so the garden reads first and the architecture second. For a house that talks about quiet connection with its surroundings, that hierarchy is the right one.

Passages That Frame the Garden

If you want to understand the "flow" in the name, look at the corridors. A covered walkway runs under a slatted timber ceiling, flanked by large-leaf plants and ending at a tall wood pivot door. Another concrete-walled passage, lined with wood overhead, finishes in a large picture window packed with tree canopy. These are not leftover spaces between rooms; they are designed as destinations.

The recipe is consistent: concrete walls on the sides, warm timber above, and a planted view at the end. Moving through the house becomes a sequence of framed gardens. We think this is where the project is strongest, because it delivers on the brief through ordinary daily movement rather than through one heroic room.

Filtered Edges and Borrowed Views

Vertical timber slats do a lot of work along the house's edges. In one courtyard they open onto planting and throw striped shadows across the paving; on a narrow timber-clad balcony with a glass balustrade, they frame distant hills while leaf shadows move across the floor. The slats screen, shade and frame at once, which is about as much as you can ask of a single detail.

An open corner hung with vintage wooden tennis rackets against board-formed concrete shows the lighter side of the house. It is a personal touch set against a structural wall, with the treetops doing the rest. These moments matter, because a house that claims not to dictate how people live has to leave space for the occupants' own objects and habits.

Living Rooms Pointed at the Horizon

The social rooms are furnished low and kept quiet so the view takes over. In the main living room, a low sofa, timber armchairs and wood shelving open onto a distant mountain line under heavy cloud. In the living and dining space, exposed timber beams, built-in wine shelving and round oak tables sit against a concrete wall in warm light.

A separate lounge, with a grey sofa, sheer curtain and timber ceiling, faces a glass-guarded edge filled with tropical leaves rather than a long view. That variation is worth noting. Not every room gets the horizon; some get the near garden. The house offers different degrees of openness, which suits the idea of residents choosing where and how to spend their time.

Private Rooms in the Same Palette

The bedrooms and bathrooms do not switch to a softer, domestic vocabulary. A bedroom corner keeps the board-formed concrete wall and adds an oak headboard panel and a slatted bedside table, softened by a sheer curtain. The double vanity pairs oak drawer fronts with a stone countertop and a slatted timber shelf. The materials are the same as the public rooms, only closer to the body.

The stone bathtub set beside a concrete wall, with broadleaf plants and a floor-mounted tap catching a shaft of sunlight, is the most atmospheric image in the set. It shows how the planting continues indoors in the private zones too. Bathing here is close to bathing in the garden, without giving up privacy.

Water, Lawn and the Outdoor Room

From above, the pool reads as a clean turquoise rectangle edged in stone, with steps and a small spa built in. It is plain geometry, and it works as a counterweight to the irregular planting around it. Teak loungers along its edge, seen earlier at sunset, turn the terrace into the house's largest room.

A covered terrace with a round mirror and a glass wall facing the lawn shows how the edge between inside and outside blurs. Under the roof, you are technically outdoors, but the space is fitted out like an interior. This in-between zone is where Brazilian modern houses have always done their best work, and Flow House continues that line competently.

Plans and Drawings

The two site plans explain how the slope is used. The lower level holds an L-shaped building with garage bays and the rectangular pool, tucked into the grade. The main level arranges a bedroom wing and a living pavilion around the pool, reached by a curving driveway that winds through the trees. Splitting service and parking below from living above keeps cars out of sight from the main floor.

Read alongside the photographs, the plans confirm that the house is a set of linked pavilions rather than one compact block. Distances between rooms are deliberate, and the passages connecting them carry the garden views. That arrangement is why circulation feels so central to the experience of the house.

Why This Project Matters

Flow House does not reinvent the Brazilian country house, and it does not try to. Its value lies in restraint: a narrow palette of board-formed concrete, timber and stone, a roof that stays thin and low, and a plan that follows the ground instead of fighting it. At 1,530 m², the house could easily have been overbearing. Splitting it into pavilions and treating circulation as the main experience keeps it at a human scale.

For architects working on large private residences, the lesson is that a brief about freedom and fluidity is best answered with fewer moves, not more. Give the corridors views, let the landscape lead, repeat a small set of materials until they feel inevitable, and leave the occupants room to make the place their own. Felipe Caboclo Arquitetura does exactly that here.
