Garden room project · Sanctum Garden Studios

Sanctum Garden Studios designed this office/music room to sit within sections of derelict walls
Sanctum Garden Studios  4m × 2.4m office and music room between derelict walls

A client approached Sanctum Garden Studios with a distinctive request for a garden office/music room that could fit between sections of a derelict wall, featuring access doors on both sides. This required a bespoke solution that balanced functionality with aesthetics while making the most of the available space.

Sanctum Garden Studios’ client, an architect, chose the Contemporary Overhang range as the foundation for the design. By collaborating closely, they developed a layout and specification that fully utilised the space.

At a glance

  • Size: 4m × 2.4m, based on the Contemporary Overhang range.
  • Roof: Slopes side to side rather than front to back, so both elevations share the same profile, with a 200mm overhang on all sides.
  • Access: Anthracite Grey uPVC doors on the front and back, giving a way through to both parts of the garden.
  • Cladding and sound: Engineered timber weatherboard in dark grey, and an insulation system chosen to reduce sound for band practice.
  • Company: Sanctum Garden Studios, who worked the layout and specification out with the client.

Design

A customised design: compact yet functional

The final design measures 4m x 2.4m. Unlike the standard roofline of the Contemporary Overhang range, which slopes front to back, this building’s roof slopes side to side, creating a uniform profile on both elevations. The roof overhang extends 200mm beyond the walls on all sides, enhancing the structure’s modern appeal.

Access

Accessible from both sides

Anthracite Grey uPVC doors were installed on the front and back elevations. Each wall features single-glazed doors, with one set including a full-height glazed panel for additional natural light. This layout allows through-access to both parts of the garden, ensuring the room remains bright and practical.

Cladding

Durable engineered wood cladding

Sanctum Garden Studios typically use a mix of Western Red Cedar and treated Redwood cladding for their Contemporary range. For this project, the client opted for a sleek, engineered timber weatherboard with a vertical grooved profile. Finished in dark grey to match the windows and roof trims, this material delivers a cohesive, modern aesthetic. It also provides a low-maintenance, durable exterior, resisting warping and cracking while withstanding the elements.

Acoustics

Acoustic insulation for band practice

As the garden office was also intended as a band practice space, the client requested a specialised insulation system with enhanced acoustic properties alongside thermal performance. Sanctum Garden Studios accommodated this by using an insulation system that reduces sound transmission while maintaining excellent thermal efficiency. This ensures the garden office is comfortable and quiet, even in colder months.
