Garden Room Directory


Ark Design Build, specialising in bespoke garden office buildings, was established by two lifelong friends. They leverage over twenty years of experience in the design and build industry. Based in Tunbridge Wells, their focus is on projects in Kent, East Sussex, Surrey & South London, prioritising the attention each unique project requires.

Ark Design Build crafts every garden office on-site using insulated timber frames. These multi-layered buildings utilise top-grade materials. By avoiding pre-fabricated, factory-built kits, they maintain a flexible approach to design and construction. This also allows them to make on-site adjustments and modifications as required.

Ark Design Build offers a comprehensive turnkey service, handling all aspects of the project. This includes dealing with planning applications, installing foundations, managing the construction process, and completing final electrical connections. They ensure clients are left with a ready-to-use office space.

Ark Design Build’s turnkey approach provides clients with the comfort of knowing the quoted price covers the entire project. This eliminates hidden costs, distinguishing them from competitors who often exclude key elements from their initial costing or require these to be organised separately.

The Ark Design Build team collaborates closely with clients to design an office building that meets their unique needs. The team provides a variety of door and window styles to choose from, allowing clients to customise their ideal layout. Their comprehensive electrical package includes Cat 6 data cabling, ensuring a reliable internet connection between the main house and the garden office—a feature often only provided as an optional extra by other companies.

Ark Design Build can incorporate additional features such as kitchenettes, cloakrooms, or complete shower rooms into their designs. They handle all the associated groundwork and connections for these elements as part of their turnkey service, ensuring that each feature is signed off by Building Control.

Examples of Ark Design Build exterior finishes

When it comes to the exterior cladding for an Ark Design Build garden office, the choice ultimately lies with the client, dictated by their preferences and budget.

Ark Design Build provides a range of wood cladding options, from cost-effective choices like Siberian Larch or Thermowood, to the more premium Western Red Cedar. Each of these finishes boasts natural resistance to rot and fungal attacks, offering extended, low-maintenance lifespans. The claddings can weather to a silver-grey if left untreated without compromising their durability. If clients prefer to maintain the original colour, Ark Design Build can apply a UV-oil during the cladding installation.

Clients can choose their preferred cladding profile and decide whether the cladding is fixed horizontally or vertically.

In addition to cladding, Ark Design Build also provides a selection of door, window, and exterior lighting options. Their commitment to bespoke design and on-site construction means they are not constrained by a set palette of finishes, fixtures and fittings, ensuring that each garden office is crafted precisely to the client’s specifications.

Inside, Ark Design Build garden offices feature high-spec plastered and decorated walls and ceilings with a wide palette of flooring options. The final result is a light, modern room like that found in newly built homes, as seen in these images.

Ark Design Build offers a comprehensive electrical specification, including Cat 6 cabling for a reliable internet connection between your house and office. Their turnkey service ensures the final connection between the office and house is taken care of by their own electrician, a service that many other companies often require you to organise with another company.

The Ark Design Build team is always ready to incorporate any unique features or fittings you want into your garden office. It all begins with a conversation!
