Swift Unlimited  7m × 4m garden gym

Western Red Cedar is a popular choice for garden room cladding due to its durability and low maintenance requirements. However, alternative options like Siberian Larch cladding also provide excellent longevity and unique character, making them a compelling choice for garden buildings.

At a glance

  • Size: 7m × 4m and 2.95m high.
  • The site: Surrounded by trees with preservation orders, so the design and construction methods were adapted to meet the requirements.
  • Exterior: Waney-edge larch, left untreated to weather to a silvery grey beside the trees, with detailing round the angled buttresses either side of the doors and paler grey frames ordered to match.
  • Inside: A SIPs core, plastered and decorated walls, rustic engineered wood flooring chosen by the clients, full wiring and air conditioning.
  • Company: Swift Unlimited, who worked with the clients on a design to suit the woodland setting.

The site

Bespoke design to suit any setting

As bespoke garden room designers, Swift Unlimited offers a wide range of exterior cladding finishes to suit individual styles and surroundings. In one recent project, their team collaborated with a client to create a design that harmonised with its natural setting.

The chosen site for this gym building was surrounded by trees protected by preservation orders. Experienced garden room providers like Swift Unlimited are well-versed in adhering to such regulations, adapting their designs and construction techniques to meet the necessary requirements.

Cladding

Seamless blending with the environment

To ensure the new building blended seamlessly with its woodland environment, the team selected waney-edge larch cladding. This material boasts a stunning natural colour, and the layered boards add depth and texture to the structure. The Swift Unlimited team further enhanced the design with carefully crafted detailing around the angled buttresses flanking the doors.

When left untreated, the larch cladding will naturally weather to a silvery grey, which complements the surrounding trees beautifully. For a cohesive look, the clients opted for a paler grey finish on the doors and windows, custom-ordered by the Swift Unlimited team-showcasing the flexibility of their bespoke service.

A durable, year-round garden space

The garden room measures 7m x 4m with a height of 2.95m. Built with a highly insulated SIPs core, it features a fully plastered and decorated interior, with engineered wood flooring in a rustic finish selected by the clients.

Fully equipped for year-round use, the room includes complete electrical wiring and an air conditioning system to maintain a comfortable temperature throughout the seasons.
