Garden Room Directory


Under the guidance of Martin and Cath Lawson, Swift Unlimited has been specialising in designing custom garden gyms across the UK for over 16 years. Combining modern aesthetics with practical design, they utilise Structural Insulated Panels (SIPs) to craft comfortable, thermally efficient exercise spaces for all seasons.

Every garden gym from Swift Unlimited is tailored to the individual needs of each client, with a focus on specific size, shape, or design features. To inspire and streamline the design process, Swift Unlimited provides a selection of predesigned options that can be customised to suit personal tastes. Their modular system ensures precise placement of doors and windows and can accommodate even the most challenging of sites. Moreover, Swift Unlimited can also supply their designs as self-build kits, offering you the unique opportunity to construct your personalised garden gym.

Swift Unlimited is adept at crafting personalised garden gyms, with a portfolio that includes fully-equipped gyms and specialised studios for activities like yoga, pilates, and ballet.

During the design process, Swift Unlimited encourage customers to formulate a wishlist of features and to share images of elements they wish to incorporate in their home gym. This information forms the foundation of their design process, with revisions undertaken until you are happy with the design.

Armed with an understanding of your intended gym use, Swift Unlimited is able to enhance the structural elements of the floor, walls, and roof. This ensures they can support the weight of essential equipment and accommodate wall and ceiling-mounted apparatus.

A bespoke designers Swift Unlimited can design buildings taller than 2.5m, unlike many other companies, creating increased ceiling height within the room. As part of their turnkey service, Swift Unlimited will handle the planning approval process needed for the extra height.

As evidenced by the gallery of builds showcased above, Swift Unlimited doesn’t adhere to set ranges of garden room designs. Rather, every project they undertake is uniquely tailored to the client’s tastes and requirements.

Swift Unlimited employs Structural Insulated Panels (SIPs) in the construction of their multi-layered buildings. This, paired with high-spec doors and windows, ensures garden gyms that are designed for comfortable year-round use. To augment comfort, they offer a range of heating and cooling systems, including underfloor heating and air conditioning systems that enable you to maintain an optimal workout temperature.

During the design process, the Swift Unlimited team collaborates with each customer to devise a tailored electrical specification. They carefully consider your intended use of the gym and the planned placement of key equipment, resulting in an electrical plan that shows the location of each socket and switch. This electrical specification can include data cabling for stable internet connectivity and audio-visual cabling. As part of their comprehensive turnkey service, they manage the installation of electrics and connect them to your home’s mains supply, leaving you with an gym that is ready for immediate use.

In addition, Swift Unlimited can enhance their designs with features such as kitchenettes, cloakrooms, and full shower rooms. They oversee all the necessary groundwork and connections, offering a seamless, project-managed service.

Where required, Swift Unlimited assists with securing planning approval and adhering to Building Regulations, guaranteeing a professionally and efficiently managed project from start to finish. This allows you to sit back and watch your envisioned gym space materialise before your eyes.

For peace of mind, Swift Unlimited offers deposit protection insurance and a 10-year, insurance-backed structural warranty.

Examples of Swift Unlimited exterior finishes

In terms of their garden gym exteriors, Swift Unlimited prides itself on sourcing the finishes and incorporating the design features you envision. This ethos is reflected in their name, ‘Swift Unlimited,’ underscoring their commitment to offering boundless options rather than confining customers to a standard palette of options.

Swift Unlimited can source a wide range of exterior finishes for their garden gyms, from durable timber finishes like Western Red Cedar to contemporary render systems or traditional stone finishes and hard-wearing, low-maintenance composite cladding options.

As shown in these images, they offer different cladding profiles, each with a unique aesthetic. Swift’s team is skilled in combining exterior cladding finishes to create a stylish appearance.

The roofs of their gym buildings are equipped with highly durable, one-piece EPDM coverings to prevent leaks. They also offer living roof systems planted with low-maintenance Sedums for year-round appeal.

Customisation extends to door and window configurations as well. Using high-spec powder-coated aluminium frames, Swift Unlimited can facilitate everything from floor-to-ceiling glass walls to perfectly placed desk-height windows. They even specialise in incorporating triangular windows for a distinctive look. They work closely with you to create the perfect glazing setup for your garden gym.
