Porto Neves Arquitetura Builds a Eucalyptus-Framed Beach House on the Maragogi Seafront

Maragogi sits on a strip of Alagoas coastline known for turquoise reef pools, but the town's residential architecture rarely rises to the intensity of its setting. Porto Neves Arquitetura, led by Adriana Porto and Luciana Neves, took on that gap with the Beira-Mar Residence, a 325-square-meter beach house that uses a hybrid steel-and-concrete frame to create generous double-height voids while cladding nearly every visible surface in eucalyptus and solid wood. The result is a house that feels simultaneously open and sheltered, industrial in its bones and handmade in its skin.

What makes the project worth studying is how it negotiates the tension between transparency and privacy on a seafront lot. The rear elevation dissolves into glass toward the ocean and pool terrace, while the street facade retreats behind a vertical eucalyptus fence and a vine-covered pergola that filters western sun. The five suites are split across two floors, with a central void knitting them together vertically. It is a house organized around a single spatial idea: every room should feel the presence of the sea, even when it cannot be seen directly.

Arriving Through a Green Threshold

From the street, the house is almost invisible. A tall eucalyptus fence and a gabled terracotta tile roof are the only signals of habitation. The west-facing entry side is deliberately restrained: a timber pergola dripping with flowering vines creates a shaded corridor that doubles as a carport and an atmospheric decompression zone. By the time you reach the pivot door, framed in climbing purple bougainvillea at dusk, the temperature has dropped and the noise of the road has faded. It is landscape architecture doing the work of walls.

The pergola is not decorative. It is a passive cooling strategy, blocking the harsh western sun from the main living spaces while allowing air to move freely through the slatted timber structure. Porto Neves Arquitetura treats vegetation as a building material here, and the result is an entrance that feels grown rather than constructed.

A Double-Height Core That Pulls the House Together

The central void is the heart of the project. A double-height living space rises beneath exposed timber scissor trusses made from plump eucalyptus logs, their raw geometry left unapologetically visible against the pitched ceiling. An open-tread timber staircase with diagonal steel bracing climbs one wall, while a mezzanine bridge on the upper floor connects the main suite to the two secondary bedrooms. Light enters through a triangular skylight opening at the stair's apex, casting a shifting wedge of sun across the interior throughout the day.

The spatial strategy is simple but effective. By concentrating vertical drama in the center, the architects allow the perimeter rooms to maintain more intimate ceiling heights without feeling compressed. You always know where you are in this house relative to the void, which acts as an orientation device as much as a social space.

Living Open to the Sea

The rear elevation is the house at its most extroverted. Floor-to-ceiling glass walls slide open to merge the living room, kitchen, and integrated balcony with the timber deck and swimming pool beyond. Hammocks hang from the covered terrace beams, and coconut palms frame the view toward the Atlantic. The terrace runs the full width of the facade, creating an uninterrupted outdoor room that is, in practice, where the house's daily life happens.

Porto Neves Arquitetura made a deliberate choice to push all service rooms to the side elevation, facing a wall rather than the sea. This utilitarian sacrifice is what allows the social spaces to achieve their panoramic openness. It is a trade-off that beach houses often fumble, cluttering the prime frontage with bathrooms or storage. Here, hierarchy is clear and unapologetic.

Timber, Concrete, and the Color of Water

The material palette is deliberately limited: burnt cement floors, horizontal timber cladding, solid wood furniture, and woven pendant lights. The kitchen bar features a timber counter backed by horizontal slatted screens, while the dining area gathers around a thick solid-wood table beneath the mezzanine. The coating materials throughout the house allude to sea colors, with blue-green accents appearing on tile and textile, though the dominant tone remains the warm amber of eucalyptus.

What keeps the interiors from tipping into resort-style cliché is their roughness. The burnt cement is left imperfect. The timber slats are not polished to a mirror finish. A stacked-stone wall on the outdoor dining terrace adds geological texture. The mood the architects describe as "rusticity and simplicity of beach life" reads as genuine here because the materials carry actual weight and grain rather than performing casualness.

Five Suites Between Palms and Timber

The bedrooms lean into the same material logic as the common spaces but dial down the scale. Fluted timber headboard walls, open closets designed for "practicality and lightness," and glazed doors that swing directly onto palm-lined terraces define each suite. The ground-floor rooms enjoy direct access to the garden, while the upper suites look out over the canopy. A glass partition in one bedroom separates the sleeping area from the covered terrace, keeping the exposed beam ceiling continuous across both zones.

The bathrooms deserve a separate mention. Twin white basins sit on timber counters beneath walls of green stone tile, and a vertical garden climbs one wall, bringing the exterior landscape inside in the most literal way possible. Upstairs, a planked ceiling with exposed rafters runs the length of the hallway connecting the suites, reinforcing the structural honesty that characterizes the entire house. Even the circulation spaces feel considered rather than residual.

Structure as Expression

The mixed structural system of metallic pillars and beams with concrete slabs is visible throughout the house, but it is the timber that gets the starring role. The eucalyptus scissor trusses, the diagonal bracing at the staircase, and the deep timber soffits all express the loads they carry. Porto Neves Arquitetura does not hide the steel columns, but they are painted to recede while the wood advances. The hierarchy is clear: steel does the heavy lifting, wood tells the story.

From the garden facade, the two-story composition reads as a layered assembly of horizontal planes, vertical timber screens, and the terracotta pitched roof above. The eucalyptus fence at ground level, the glazed living pavilion behind it, the upper balcony with its timber bracing, and the roofline each occupy a distinct visual register. It is a legible building, one you can read from the outside and predict the interior experience with reasonable accuracy.

Plans and Drawings

The site plan confirms what the photographs suggest: the building volume occupies the center of the lot with the pool and deck to the rear and the pergola and planted beds to the front. The ground-floor plan shows the central open space flanked by the two ground-level suites and service rooms, while the first-floor plan reveals how the double-height void carves through the center, separating the main suite from its two neighbors and connected by the timber walkway bridge.

The sections are especially revealing. One shows the pitched eucalyptus roof structure clearly, with the scissor trusses spanning the full width; the other shows the relationship between the flat-roofed terrace overhang at the rear and the gabled volume above. The elevations cycle through the building's four faces, each with a distinct character: the slatted fence and single palm on the street side, the fully glazed ocean-facing facade, and the more closed lateral walls. Together, the drawings confirm that the apparent simplicity of the house is the result of careful calibration, not casualness.

Why This Project Matters

Beach houses in northeastern Brazil face a familiar trap: they either over-design for Instagram or default to generic tropical resort vocabulary. The Beira-Mar Residence avoids both by grounding its decisions in specific site conditions and honest material expression. The vine-covered pergola is not a styling choice; it blocks western sun. The open closets are not a design trend; they acknowledge the humidity and sandy informality of coastal living. The eucalyptus is local, structural, and beautiful without needing to be anything else.

Porto Neves Arquitetura has produced a house that is generous without being excessive. At 325 square meters with five suites, it is not small, but the spatial economy is tight. Every gesture serves at least two purposes: the central void is both a light well and a social connector; the terrace is both circulation and destination; the timber structure is both load-bearing and decorative. That kind of disciplined integration is what separates a good beach house from a memorable one.
