Garden Room Directory


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

Every garden office is custom-built to meet the specific needs of each client. The team collaborates closely with you to create a space that fulfils your exact requirements, whether that entails a particular size, shape, or unique design features. Swift Unlimited is adept at crafting workspaces that cater to individual workers as well as spacious environments suitable for conference rooms. They invest time in understanding your business dynamics, ensuring that the elements integrated into the design enhance your workflow. Over the years, their expertise has been leveraged to build diverse business premises, including garden hair salons and a commercial kitchen for a cake designer. A Swift Unlimited building serves as a professional storefront where you can meet with clients, offering the convenience of working from home while preserving a professional boundary between work and family life.

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.

The Swift Unlimited design team collaborates closely with you to select the exterior and interior finishes that encapsulate the aesthetic you envision. They encourage customers to formulate a wishlist of features and to share images of elements they wish to incorporate in their office. This information forms the foundation of their design process, with revisions undertaken until you are happy with the design.

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 offices 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 working 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 office and the planned placement of key furniture items, 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 office 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 office 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 office 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 offices, 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 garden offices 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 office.

Examples of Swift Unlimited interior finishes

As seen in these photos, Swift Unlimited’s office buildings feature plastered and decorated interiors, creating light modern workspaces. They offer an array of flooring options, along with blinds for doors and windows, allowing clients to customise their working environment.

Swift Unlimited also provides a comprehensive electrical package that can be customised to suit specific needs. This includes well-placed power points, LED downlighting lighting, and reliable internet solutions such as data cabling for uninterrupted connectivity. If desired, they can also integrate audio-visual systems into the office design.
