Felipe Caboclo Splits a Concrete Prism into Four Garden-Laced Volumes on a Brazilian Hilltop

A single rectangular prism, sliced into four pieces and pulled apart so that gardens can breathe between them: that is the governing idea behind Tetra House, completed in 2022 by Felipe Caboclo Arquitetura at Fazenda Boa Vista near São Paulo. The 2,300 square meter residence sits on the highest point of a steeply sloping site, and rather than carving into the hill, it hovers above it. Four blocks alternate with planted voids along a linear path, producing an L-shaped mass that concentrates its bulk toward the north and west while directing every habitable room toward the main view.

What makes the project genuinely compelling is not the size, which is considerable, but the structural audacity that holds it all up. Tree-like concrete pillars branch from single base points, suspending upper volumes over landscaped ground. The result is a house that reads less as a building resting on earth and more as a series of inhabited canopies floating over a garden. A two-layered envelope of glass and wooden slatted louvres, a detail drawn straight from the vocabulary of Brazilian tropical modernism, wraps each volume. Privacy is achieved without opacity, and climate is managed without mechanical excess.

Branching Columns as Sculptural Infrastructure

The structural system is the project's signature move. Four angled concrete pillars spring from a shared origin and splay outward, creating a branching geometry that recalls both buttress roots and modernist pilotis, but belongs fully to neither. These columns are not hidden: they are the primary visual event at ground level, crisscrossing beneath the elevated volumes and framing planted beds of grasses, palms, and cycads. The structure becomes landscape furniture.

By lifting the habitable mass off the ground, Caboclo preserves the continuity of the hillside garden beneath the house. You walk under the building before you walk into it. The entrance and car park sit at the first floor level, not at grade, reinforcing the sensation that the terrain has been respected rather than overwritten. A double-height entry space looks down into the north courtyard, setting up the vertical drama that the concrete staircase then resolves as it descends to the ground-floor living room.

Timber Screens and the Double Envelope

Vertical timber slats wrap each volume like a second skin. The louvres sit outboard of a glass envelope, filtering sunlight and softening views without sealing them off. The technique is deeply familiar in Brazilian residential architecture, from the cobogó screens of the Northeast to the brise-soleils of São Paulo modernism, but here the scale is generous enough that the screens read as cladding rather than ornament. When seen against the board-formed concrete behind them, the timber registers as warm, rhythmic, and alive.

From inside, the slatted layer turns the surrounding landscape into a cinematic flicker of green and sky. From outside, it gives the house a uniform materiality that unifies disparate volumes. The effect is doubly useful: it controls solar gain passively and it protects privacy along the narrow walkways that connect blocks without resorting to solid walls.

Living Between the Volumes

The interiors earn their calm through proportion rather than decoration. The main living space opens directly onto a covered terrace, its timber slatted ceiling extending continuously from inside to outside so that the boundary between conditioned and unconditioned space blurs. Curved built-in seating at the terrace edge invites a slow, horizontal posture that matches the panorama beyond.

At the southern end, an outdoor dining area tucks beneath a concrete soffit flanked by angled columns, one side open to the pool. The table is long, the columns are close, and the effect is almost civic in its generosity, a covered loggia scaled for a gathering rather than a family dinner. The interplay between raw concrete overhead and the water surface beside it keeps the atmosphere honest: this is a house made of heavy materials, but it never feels oppressive.

Pool, Stone, and the Southern Anchor

The rectangular pool occupies the southern block, and its rough stone retaining wall introduces a material register absent elsewhere. Where the rest of the house is precise concrete and milled timber, the pool surround is geological: tiered, textured, and deliberately archaic. It anchors the composition to the hillside, making the floating volumes upstream feel even lighter by contrast.

A stone tower visible in the side elevation amplifies this geological quality. Standing beside an autumn-hued tree, it reads as a counterweight to the cantilevered upper levels. The pool deck, furnished with stone loungers, faces back toward the elevated structure supported by angled columns, turning the architecture itself into the primary view.

Landscape as the Fifth Room

Maria João d'Orey's landscape design is not backdrop; it is the connective tissue that makes the four-block strategy legible. White-barked trees, palms, cycads, and ferns colonize the voids between volumes, turning gaps into gardens and walkways into promenades. Large concrete pavers cross the lawn beneath the angled supports, reinforcing the idea that circulation at ground level is as much about the garden experience as about getting from A to B.

Viewed through the angled concrete beams at the courtyard, planted beds sit below while the timber screen hovers above, and the architecture reads as a frame for horticulture rather than the other way around. This is the biophilic ambition of the project at its most persuasive: the house does not contain a garden, it is perforated by one.

Dusk, Distance, and the Aerial View

A concrete terrace with a glass balustrade looks out over a forested valley at dusk, and the image captures what all the structural gymnastics are ultimately for: the view. The house is oriented so that its length aligns with the panorama, and every block catches a slightly different angle of it. The aerial photograph confirms the compositional discipline from above, with solar panels covering the flat roof and timber screens cutting neat lines through the surrounding farmland.

Along the narrow concrete walkway that runs beside the timber and glass facade, hillside vegetation presses close. The house does not push the landscape away. It invites it alongside, using the slender proportions of its blocks to maximize edge condition. Every room is a perimeter room.

Plans and Drawings

The floor plans confirm the linear arrangement: rooms string out along the site's contour, interrupted by courtyards planted with trees. The sections are the more revealing drawings. They show how the terraced volumes step down the hillside, maintaining a roughly consistent roofline while the ground drops away beneath them. One section cuts through two bathrooms flanking a central void, with the planted landscape visible below and a walking figure for scale, demonstrating how even service spaces participate in the garden dialogue.

The rendered elevation and perspective, with a lone tree on a grassy slope and a figure on the terrace, capture Caboclo's ambition in diagram form: a heavy concrete and timber volume that nonetheless appears to float, held aloft by its branching columns and framed by the emptiness around it.

Why This Project Matters

Tetra House is interesting because it takes a familiar tropical modernist toolkit, louvres, pilotis, board-formed concrete, and deploys it at a scale and with a structural boldness that pushes each element past its conventional limit. The branching columns are not functional necessities dressed up as sculpture; they are a genuine structural invention that reshapes how the ground level of the house operates. By lifting the entire program and letting landscape flow beneath, Caboclo avoids the retaining-wall-and-platform approach that dominates hillside construction in the region.

More subtly, the project proposes that splitting a house into fragments and filling the gaps with gardens produces a richer domestic experience than consolidating everything under one roof. Every room has two orientations: one toward the valley and one toward a courtyard. Every corridor is also a terrace. The result is a house that feels simultaneously massive and porous, a 2,300 square meter residence that somehow manages to avoid the hermetic quality that houses of this size almost always produce. That is the real achievement here, not the engineering but the atmosphere.
