Sorrento Beach House by Jost Architects: A Coastal Retreat with Modernist Elegance

Set in the coastal town of Sorrento, Australia, the Sorrento Beach House by Jost Architects is a stunning synthesis of contemporary design, functional family living, and architectural expression inspired by Scandinavian and mid-century modern influences. Crafted as both a luxurious holiday retreat and a future permanent residence, this 285 m² home balances bold aesthetic aspirations with the relaxed ambience of a beachside lifestyle.

A Vision of Seamless Indoor-Outdoor Living

The clients, who envisioned a super-stylish and cool coastal home, outlined a clear and challenging brief. They desired a house that could effortlessly transition between indoor and outdoor entertaining spaces, include a second-story with expansive views, and integrate a self-contained bungalow for their teenage children. A solar-heated pool, a roof deck, and at least four bedrooms were also part of their vision—along with an unusual but deliberate preference for a darker, moodier interior palette, rich with timber, stone, and glass.

Designing for Privacy and Coastal Context

Situated along a busy road, the design prioritizes both privacy and acoustic insulation. Instead of a high, opaque fence, Jost Architects incorporated a textured brick wall with a permeable batten screen and layered native landscaping to blend with the local tea tree vegetation. This approach maintains privacy while preserving the home’s openness and visual connection to the coastal setting.

Ground-Level Elegance and Functionality

At the heart of the ground floor lies a sophisticated kitchen and butler’s pantry, complete with concealed powder room, forming the functional centerpiece of the open-plan layout. Surrounding spaces include a generous master suite, a living room, and a study/guest bedroom, ensuring the layout meets both immediate family needs and long-term accessibility.

Multi-Level Living and Rooftop Views

The upper level comprises two additional bedrooms, a shared bathroom, and a secondary living space that opens onto a terrace, creating flexible living zones for different family members. One of the home's architectural highlights is the spiral staircase leading to the roof deck, offering uninterrupted views of the surrounding tea trees. This feature—developed in close collaboration with local planning authorities—adds a vertical dimension to the home’s enjoyment of the coastal landscape.

A Self-Contained Bungalow and Outdoor Sanctuary

To the rear of the property, a separate bungalow serves as a teenage retreat, complete with its own bathroom, doubling as a versatile guest suite. Behind the house, the solar-heated pool offers a resort-like atmosphere, connecting seamlessly with the landscaped garden designed by Clea Cregan of Miniscape Projects.

Materiality Rooted in Modernist and Coastal Themes

Externally, the house reflects a modernist flat-roof silhouette accentuated by vertical timber cladding, which will age gracefully into a silvered tone, harmonizing with cement-rendered brick and concrete cladding on the upper level. Inside, the palette leans dark and atmospheric: rich thermally modified timber lines the walls, ceilings, and arches, while the kitchen’s Atlas Green marble and deep terrazzo flooring inject luxury and tactility. Contrasting bagged white brickwork and curved interior forms add softness and subtle beach-inspired lightness.

Interior Collaboration and Artistic Flair

Interior designer Simone Haag played a pivotal role in refining the home’s interiors, assisting the clients with lighting and furniture selections and curating finishes to align with their bold tastes. Her collaboration also led to the inclusion of a custom mural by Charlotte Swiden in the master bedroom—a standout feature that infuses art into the architecture.

Sustainable Systems and Passive Design Strategies

Sustainability is seamlessly embedded into the architecture. The house features passive thermal control, with cross-ventilation and a stairwell designed as a thermal chimney. A strategic orientation ensures that masonry walls shield the south side, while expansive glazing on the east, north, and west is protected by custom-designed eaves to mitigate solar gain. An early-installed solar system powered the clients' primary home during construction—illustrating the home's energy-conscious planning.

Craftsmanship in Challenging Times

Special recognition goes to Ryan Waterson of Waterson Build, who delivered the project during the COVID-19 pandemic with unwavering dedication—even navigating a storm to ensure the safe delivery of key materials. This level of care and craftsmanship is echoed in every corner of the house, a testament to the collaborative spirit behind its creation.
