Atelier Data Scatters Five Timber Pavilions Through a Pine Forest on Portugal's Atlantic Coast

Most houses in protected landscapes try to disappear. Atelier Data took a different approach at Praia Grande: rather than burying a single volume into the hillside, the Lisbon studio split its program into five distinct pavilions and threaded them through an existing stand of maritime pines near the Sintra-Cascais coast. The result is less a house than a small settlement, a constellation of cork-clad buildings organized in a loose semicircle around a pool shaped to look like a natural pond. Each volume corresponds to a specific use, and the gaps between them are just as important as the rooms inside.

What makes the project genuinely interesting is not its eco-credentials, though those are substantial. It is the decision to treat existing trees as the primary generators of architectural form. The volumetric composition was literally derived from the spaces between pine trunks: where a clearing existed, a building went; where roots ran, the structure lifted off the ground on concrete bases so vegetation could continue growing underneath. The architects describe the building system as one whose every component you could theoretically eat or drink, a provocation about non-toxicity that, whether or not you take it literally, signals a materials philosophy far more rigorous than the usual sustainability checklist.

Building Among Trees

The fluted metal cladding that wraps each pavilion does double duty. Its vertical ribs catch pine shadows throughout the day, turning each facade into a kind of sundial, while the corrugation channels rainwater directly toward the sandy, porous ground below. Beneath that metal skin sits a ventilated layer of projected cork, a material so quintessentially Portuguese it borders on cliché, but here it performs a serious thermal role, keeping interiors comfortable without air conditioning in a coastal climate that swings between winter damp and summer heat.

The volumes are deliberately modest in height. None tries to compete with the canopy overhead, and several are lifted just enough to let scrubby ground cover colonize the space beneath the floor plate. It is a rare residential project where the section beneath the building is designed with as much intention as the section above it.

The Courtyard as Organizing Principle

The five buildings curve around a central pool and a series of planted courtyards that function as outdoor rooms. Sandy beds, tree stumps, and low plantings replace conventional landscaping. Pine trunks rise through the gaps between volumes, and narrow glazed corridors stitch one pavilion to the next, so the experience of moving through the house always involves crossing a threshold between interior and exterior. The entrance and kitchen sit in one rectangular building adjacent to a larger volume containing the living room, dining area, and a piano room in a single open space. Two square bedroom pavilions anchor opposite ends of the arc, each with its own private patio opening toward the pool.

The pool itself is worth noting. Designed to read as a reflecting pond rather than a conventional swimming pool, it stretches in an organic shape between the buildings, catching light from the west and mirroring pine silhouettes at dusk. Its edges blur into the landscape rather than terminating in neat coping stones.

Timber Interiors and Material Honesty

Inside, the sustainable wood structure that forms the bones of every pavilion remains fully exposed. Timber beams, slatted ceilings, and reclaimed wood staircases create a warm, tactile counterpoint to the polished concrete floors. The kitchen pairs walnut cabinetry with a timber slat ceiling and simple pendant lights, all calibrated to feel handmade without tipping into rusticity. A double-height bookshelf wall in the main living volume gives the house its most vertical moment, drawing the eye upward through a space that otherwise emphasizes horizontality and connection to the ground plane.

Corridors and Transitions

The narrow corridors that link the five pavilions are among the most considered spaces in the project. Lined in timber and glazed along one side, they frame specific views of the pine forest and planted beds while compressing the section just enough that arriving in the next volume feels like a genuine spatial release. Built-in shelving and window seats turn what could be mere circulation into usable space. Sunken thresholds and exposed beam ceilings reinforce the sense that each transition is a deliberate passage, not an afterthought.

Private Rooms, Distinct Identities

Each bedroom pavilion has its own character. One features a suspended timber bed frame with mosquito netting beneath vertical wood slats and a high ceiling, evoking a treehouse more than a conventional bedroom. Another is framed by dark timber posts with blue plaster walls and a slatted ceiling that filters light into soft horizontal bands. The separation of sleeping quarters into their own buildings, each with a private patio, gives the house a hospitality-like quality: guests arrive at their own small building, with their own outdoor space and direct access to the pool.

The bathrooms continue the project's commitment to material specificity. Pink subway tiles in one, dark green square tiles in another, and timber cabinetry throughout give each wet room a distinct palette while maintaining a shared language of natural paints and non-toxic finishes. One bathroom opens through glazed doors onto an enclosed timber deck, collapsing the boundary between bathing and garden in a way that would feel forced in a less private setting but works here because the pine canopy provides a natural screen.

Dusk and the Landscape of Light

At twilight the house reveals a second identity. Backlit timber slat screens glow amber against the darkening pines, and the reflecting pool picks up the last color from the sky. The vertical timber screens that wrap courtyard corners perform as lanterns, broadcasting warm light into the gaps between buildings. Pine trunks become silhouettes. The careful orientation of each volume, calibrated to the sun's path and to visual relationships with the Serra de Sintra mountains to the east, pays off most visibly at this hour, when the interplay of light, shadow, and reflection is at its most intense.

Site and Context

An aerial view reveals how close the house sits to Praia Grande's shoreline, nestled among farmland and coastal vegetation in a landscape that is simultaneously wild and inhabited. The Sintra-Cascais National Park designation imposes strict constraints on construction, which partly explains the project's strategy of minimal ground contact and reverence for existing vegetation. Cantilevered volumes supported by timber beams reach out beneath gnarled branches, establishing a physical dialogue between structure and tree that feels negotiated rather than imposed.

Plans and Drawings

The site plan and axonometric drawings make the organizational logic explicit: five angular volumes fanned around a central water feature, with the topography absorbed into split-level sections that tuck technical areas beneath the main living spaces. The isometric massing sequence is particularly revealing, showing how the architects tested the placement of each volume against the positions of existing trees before arriving at the final arrangement. The section drawing confirms the strategy of lifting buildings off the sloping terrain, creating usable space underneath while preserving the root systems and drainage patterns of the pine forest.

Why This Project Matters

The House in Praia Grande matters because it takes the familiar trope of building lightly on the land and actually follows through on it. The entire structure is wood, assembled in situ by Green Heritage, a construction firm specializing in sustainable building. Cork, hemp, and natural paints replace the usual catalogue of petrochemical products. Decentralized ventilation with heat recovery eliminates the need for air conditioning. None of these choices is unprecedented on its own, but the discipline of applying all of them simultaneously in a 428-square-meter residential project, within the regulatory constraints of a national park, is genuinely rare.

More importantly, the project demonstrates that ecological rigor and spatial generosity are not in conflict. The fragmented plan creates more exterior surface area, more courtyards, more moments of contact with the forest than a compact footprint ever could. By letting the trees dictate the massing, Atelier Data produced a house that feels discovered rather than designed, a cluster of rooms among pines that seems to have always been there. That is a harder trick than it looks.
