Plan storage, a worktop, sink, fridge and refreshment facilities into the room from the outset.
Hi I'm Kevin Tomlinson founder of Oakspan. I oversee every project personally to ensure your trust remains strong from our first conversation, room design, your build and handing over the keys.
With no sales team, the price and timeline I provide is the one I deliver. Real customer service means being large enough for efficiency but small enough for flexibility.
That's why Oakspan confidently provides a 10 year guarantee - with my name on it!
If you have any questions, please reach out. I'm happy to answer honestly and quickly.


Create a quiet, fully insulated workspace away from the distractions of the house—or a flexible garden room that works as an office during the day and something more when work is finished.
Kevin personally surveys, designs and prices every Oakspan project.
A bespoke garden office creates separation between home life and working life without adding a daily commute.
The room can be planned around your desk, screens, storage, natural light and the way you move through the working day. Door and window positions are considered around glare, privacy and your view of the garden—not simply placed where they are easiest to install.
Oakspan garden offices are built as proper insulated rooms rather than seasonal timber cabins, giving you a comfortable place for focused work, video calls, client meetings and creative thinking.

Many Oakspan offices support work alongside family life, hobbies or entertaining.
Deciding how the room may need to change before the layout is finalised allows storage, glazing, sockets, lighting and furniture to work around every intended use.
A quieter workspace for concentration, meetings and daily remote working.
Combine a finished workspace with a separate secure storage area.
Work during the day, then relax or entertain when work is finished.
Plan a larger room around work alongside fitness, art, music or therapy.
A practical garden office that creates a proper working environment alongside useful storage within one coordinated building.


The foundation, structure, insulation and roof are designed as one complete building system around your site and intended use.

Treated 45mm × 95mm C16 timber frame, 11mm structural OSB, breathable building paper and treated 25mm × 50mm cladding straps.
100mm mineral wool insulation combined with an additional 25mm Kingspan layer before the internal finish is completed.

The roof is protected with a durable one-piece EPDM rubber membrane for reliable long-term weather protection.
A-rated double-glazed windows and doors, secure locking systems, plasterboard walls and a complete painted interior finish.
Your electrical plan should reflect where you will sit, where equipment will be positioned and how the room may evolve.
Oakspan can plan internal and external lighting, double sockets, television points, heating and wired internet connectivity around the finished layout. This avoids extension leads, awkward cabling and sockets hidden behind furniture.
A compact kitchenette or private WC can make a garden office more independent during long working days, client meetings and multipurpose use.
Water, drainage, ventilation, access and the available floor plan are considered early so every feature feels integrated rather than added later.

Discuss Your Garden Office
I’m Kevin Tomlinson, founder of Oakspan. I personally visit your property because the details of the garden and how you intend to use the office influence every part of the finished room.
I assess access, ground conditions, levels, drainage and the proposed position before we finalise the design. We can then discuss size, glazing, layout, storage, electrics and finishes with a proper understanding of what is practical.

The size of the room is an important factor to consider when planning a garden office. It should be spacious enough to accommodate your furniture and other items, as well as provide adequate ventilation. It is best to choose a room that is slightly bigger than what you think you need, to ensure that you are comfortable
When it comes to the design of a garden office, there are many options to choose from. You can opt for a traditional building, or a modern, minimalistic garden room. You can also create a space that is designed to fit in with your outdoor environment. When it comes to office furniture, you can choose from a range of designs and materials, such as wood, metal, or plastic. You should ensure that your furniture is suitable for the environment and is comfortable to use.
To ensure that your garden office is comfortable and productive, it is important to consider the electrics. This includes power and wiring for lights, sockets, and heating. You should also consider installing a broadband connection as well as any other technology that you need to work effectively.
Insulation is an important factor to consider when designing a garden office. This helps to keep the room at a comfortable temperature, while also reducing energy bills. When it comes to garden offices, there are many insulation materials to choose from to cover your roof, walls and flooring.
It is also important to ensure that the building is insulated from the outside. This can be achieved by using a variety of materials such as cladding, insulation boards, or even a double wall system. This helps to protect the office from the elements and ensures that it is comfortable to use.
Windows & Doors are an important part of any garden room office. Patio doors, bifold doors, and French doors are all popular choices for garden room offices. These doors are usually double glazed, providing an insulated and secure locking system. Natural light is allowed to enter the space, creating a pleasant and inspiring atmosphere. These doors also allow users to easily transition from inside to outside, allowing them to enjoy the beauty of nature while still working in an ultra-modern and comfortable office space.
The garden room office provides a unique and comfortable working environment, combining the convenience of a traditional office with the calming atmosphere of a garden space. It allows users to enjoy natural light, fresh air and calming views of nature, providing an inspiring and productive space. The insulation helps to ensure that the office space remains comfortable, while also blocking out external noise and distractions. The garden room office is an ideal solution for those who want to work in a peaceful, natural and comfortable environment.
