Main Facts: A Masterclass in Coastal Modernism
Coastal architecture often walks a fine line between conquering the elements and succumbing to them. Too often, beachside homes either retreat behind fortress-like walls to shield themselves from salt spray and harsh sun, or they dissolve into fragile glass boxes that require heavy mechanical intervention to remain habitable.
Enter the Ocean House, a striking new residential project designed by the Brazilian practice Biazus Arquitetura and curated for publication by Susanna Moreira. Photographed extensively by Cristiano Bauce, this coastal sanctuary strikes a profound balance between monumental presence and breezy, open-air domesticity.
Commissioned as a multi-generational family retreat, the brief demanded a dual-purpose architectural identity. First and foremost, it needed to serve as a comfortable, enduring residence where a family could comfortably settle in for extended stretches of beachside living. Simultaneously, it had to function as a dynamic, welcoming social hub capable of hosting a revolving door of friends and guests over bustling weekends.
To achieve this, Biazus Arquitetura leaned heavily into the psychological and physical strength of horizontal planes. Low-slung, sweeping roofs and extended overhangs create deep pockets of shade, mitigating the intense tropical sun while establishing a seamless dialogue with the flat, expansive horizon of the ocean. Inside, the home unfolds as a masterclass in spatial choreography. Split-level zones and dramatic double-height ceilings carve out distinct functional areas without ever erecting rigid barriers. The material palette remains intentionally grounded, relying on an honest expression of raw stone and warm wood that weathers gracefully alongside the coastal environment.
Chronology: The Evolution of the Ocean House Project
The realization of the Ocean House was a deliberate, multi-phased journey that moved from initial client consultations to the final interior styling captured by Cristiano Bauce.
Phase 1: Conceptualization and Briefing (Early Development)
The project began with a clear set of parameters laid out by the clients. Recognizing the need for a home that could effortlessly transition from quiet family periods to high-energy weekend gatherings, Biazus Arquitetura conceptualized a layout centered around volumetric integration. The team decided early on that horizontal planes would dictate the architectural language, grounding the structure visually and functionally.
Phase 2: Spatial Planning and Engineering
During the design development stage, the architects mapped out the split-level living zones and the primary double-height gathering spaces. Structural engineering focused heavily on cantilevers and overhangs, designed to cast protective shadows and regulate indoor microclimates without heavily relying on air conditioning.
Phase 3: Material Selection and Sourcing
A critical milestone in the timeline was the curation of the material palette. Biazus Arquitetura prioritized tactile, enduring elements. Locally sourced stone and sustainably harvested timber were selected not only for their aesthetic warmth but for their resilience against corrosive sea salt and high humidity.
Phase 4: Construction and Finishing
The build phase emphasized precision craft, particularly in aligning the heavy horizontal concrete and timber lines with the fluid, organic landscape of the coastline. Interior detailing focused on acoustic dampening for the double-height spaces and fluid indoor-outdoor transitions.
Phase 5: Completion and Public Reveal (September 2026)
With interior styling finalized and photography by Cristiano Bauce completed, the Ocean House officially debuted to the architectural world, drawing critical acclaim for its sophisticated interpretation of contemporary tropical architecture.
Supporting Data & Architectural Specifications
To truly understand the operational success of the Ocean House, one must examine the metrics, materials, and spatial strategies employed by Biazus Arquitetura:

Official Responses and Design Philosophy
In their official design statement, the architects at Biazus Arquitetura elaborated on the core philosophy driving the project:
"Architecture that relies on the strength of horizontal planes to create shade, comfort, and presence."
This succinct manifesto captures the essence of the Ocean House. Rather than striving for verticality—which often alienates a structure from its natural coastal context—the architects used horizontality to anchor the building into the earth while mirroring the low, wide expanse of the sea.
Furthermore, the design team addressed the specific behavioral patterns requested by the clients:
"At the client’s request, we developed a home for the family to spend extended periods at the beach while hosting many friends on weekends. The project features an integrated living area with split-level spaces and double-height ceilings, utilizing natural materials such as stone and wood."
By avoiding a rigid cellular floor plan, Biazus Arquitetura ensured that whether the house is occupied by a small family unit on a quiet Tuesday evening or dozens of guests on a Saturday afternoon, the spatial volume adapts fluidly. The split-level design allows for subtle zones of privacy—nooks where a family member can read undisturbed—while the double-height central living area acts as the beating heart of the home, drawing people together under soaring timber-lined ceilings.
Implications: Setting a New Benchmark for Coastal Architecture
The completion and reception of the Ocean House carry broader implications for contemporary residential design, particularly in sensitive coastal zones.
1. The Revival of Passive Climatic Design
In an era dominated by fully glass-enclosed structures that demand immense energy loads for cooling, the Ocean House demonstrates the efficacy of traditional passive strategies reinterpreted through a modern lens. The heavy horizontal planes and deep eaves act as architectural brise-soleils, intercepting high-angle summer sun before it can penetrate the interior glass walls. This approach drastically reduces solar heat gain while fostering natural cross-ventilation from ocean breezes.
2. Material Honesty and Durability
Coastal environments are notoriously brutal on building materials. By anchoring the design in raw stone and robust wood, Biazus Arquitetura avoids superficial finishes that quickly degrade under corrosive maritime conditions. Instead, the chosen materials are expected to patina gracefully over time, acquiring a textural richness that ties the building even closer to its natural environment.
3. Flexibility in Modern Living
The pandemic and the rise of remote work have fundamentally shifted how we view secondary homes. Properties that were once used strictly for two-week summer vacations are now expected to function as fully equipped secondary offices and long-term living quarters. The Ocean House responds directly to this shift. Its robust programmatic layout proves that a beach house does not have to choose between being a cozy family haven and a sprawling party venue—with intelligent spatial planning, it can effortlessly be both.
As Biazus Arquitetura continues to influence the trajectory of modern South American design, the Ocean House stands out as a triumph of contextual sensitivity, structural clarity, and timeless elegance.
