Executive Garden Rooms  6.2m × 3.5m cedar-clad garden office in Swanage

Executive Garden Rooms specialises in transforming outdated spaces into modern, functional garden rooms. This recent project in Swanage showcases their ability to replace a 1930s garage with a stylish garden office featuring a hidden storage area-designed to enhance both usability and appearance.

At a glance

  • Size: 6.2m × 3.5m, built on the footprint of the 1930s garage it replaced.
  • Layout: An office with a glazed corner looking onto the newly landscaped garden, and a storage room to the right behind a grey panel door in the side wall.
  • Electrics: Power sockets, LED lighting and a smoke detector, with CAT6 data cabling from the house and a Daikin air conditioning unit that can be adjusted over wifi.
  • Exterior: Western Red Cedar treated with UV-protective oil to keep its colour, and Cedral fibre cement board on the less visible rear wall.
  • Company: Executive Garden Rooms, who took down the old garage and handled every stage through to decoration and the electrical connection, finishing in two and a half weeks.

Turnkey service

Complete turnkey service, from demolition to final touches

Unlike many garden room providers that require a cleared site, Executive Garden Rooms offers a full turnkey service. For this project, their team began by dismantling the old garage, managing every stage through to final decoration and connecting the electricity. The finished office occupies a 6.2m x 3.5m footprint, making the most of the available space.

Layout

Home office with hidden storage

The building is divided into two spaces: a bright, inviting office and a discreet storage room. The main office area features a glazed corner that frames the view of the newly landscaped garden, creating a pleasant working environment. To the right of the office, a hidden storage room is accessed through a sleek, grey panel door on the side wall, providing valuable storage without compromising the office’s aesthetic.

Electrics

Wired for connectivity and year-round comfort

Executive Garden Rooms provides a comprehensive electrical package tailored to client needs. This includes ample power outlets, LED lighting, and a smoke detector for safety. Reliable internet access is ensured with CAT6 data cabling from the main house, providing a more stable connection than plug-in options. For climate control, the clients chose a Daikin air conditioning unit with Wi-Fi connectivity, allowing remote adjustments for a comfortable workspace in any season.

Exterior

UV-protected Cedar and Cedral exterior

The exterior of the garden office is clad in Western Red Cedar, treated with UV-protective oil to maintain its natural colouring and prevent weathering. For the rear wall, which is less visible, Cedral fibre cement board was used, offering a durable, low-maintenance solution that resists rot and fading.

Fast and efficient transformation

Executive Garden Rooms completed this project within 2.5 weeks, transforming an outdated garage into a sleek, modern office.

The owners expressed their appreciation for the professional service and quality results provided by Executive Garden Rooms:

We would highly recommend Executive Garden Rooms to anyone considering building a garden office but unsure where to begin… From start to finish, the project ran like clockwork, and we were kept informed at every stage. There were no hidden costs, and the turnkey approach meant we didn’t have to coordinate multiple contractors. The quality and finish of the build are outstanding. We can’t thank the team enough for replacing our obsolete garage with a wonderful office space in under 2.5 weeks!”
