In Byron Bay, Australia, Harley Graham Architects created a compact backyard studio that feels open, relaxed, and perfectly suited to the subtropical climate. Known as Marvell St Studio, the project was designed as a separate space for the homeowners’ parents and visiting friends, adding flexible accommodation to a typical quarter-acre suburban block.
The 645-square-foot (60sqm) studio takes inspiration from mid-century modern design while embracing indoor-outdoor living in a very Australian way. Drawing from the architects’ description, the structure was planned to make the most of leftover garden space, with operable edges that allow the building to completely open to the outdoors and even function like an oversized pergola connected to the backyard.
Making the Most of a Backyard Footprint
Instead of treating the studio as a secondary structure hidden behind the main home, the architects approached it as an extension of the garden itself. Timber cladding made from Australian Tallowwood gives the exterior a warm, natural appearance, helping the building settle comfortably into the leafy Byron Bay setting.
Large sliding glass walls completely transform the structure when opened, dissolving the line between inside and outside. The result feels less like a traditional granny flat and more like a breezy pavilion where fresh air and garden views become part of the experience.
Warm Materials Shape the Interior
Inside, the palette is simple but inviting. A timber ceiling stretches throughout the studio, adding warmth above polished concrete floors that help keep the interior cool during warmer months. The combination gives the compact footprint a clean and relaxed atmosphere without feeling minimal or stark.
A small kitchenette, built-in storage, and a compact bench provide everything needed for short stays while keeping the layout uncluttered. Natural light pours through the glass walls, making the interior feel much larger than its actual size.
A Bedroom With Its Own Identity
At one end of the studio, the bedroom can be screened off for privacy when needed. Even though the structure is compact, the separation helps the guest accommodation feel more complete and comfortable for longer stays.
One of the standout details is how the timber ceiling continues down the wall behind the bed, creating a seamless backdrop that adds texture and warmth to the sleeping area. It is a simple move, but it gives the bedroom a stronger visual identity within the open-plan design.
A Bathroom With Texture and Warmth
The en-suite bathroom introduces another layer of material contrast. Patterned tiles bring texture and personality to the compact space, while a warm timber vanity softens the harder finishes.
A walk-in shower keeps the room feeling open and functional, continuing the clean and relaxed design approach seen throughout the rest of the studio.
A Pool Cabana Completes the Backyard
Beyond the studio itself, the project also includes a small pool cabana with a day bed. While compact, this additional structure helps tie the entire backyard together architecturally and extends the sense of outdoor living across the property.
Combined with the studio’s fully operable walls and garden connection, the cabana reinforces the relaxed Byron Bay lifestyle the architects were aiming to create. The result is a guest space that feels welcoming, flexible, and closely linked to the outdoors.
Marvell St Studio shows how a relatively small structure can completely change the way a backyard is used. Through timber finishes, flexible open-air design, and a strong connection to the garden, Harley Graham Architects has created a guest space that feels airy, practical, and perfectly suited to Byron Bay’s subtropical lifestyle.
