If you need more space at home but don’t want the disruption of moving or extending, a garden room can be a practical way to add usable space without changing the main house. At OuterRoom, we design and build garden rooms in Leatherhead that are made to suit the property, the garden and the way you want to use the room every day.

Every garden has its own layout, levels and character, so we design each room to suit the space rather than forcing a standard design into place. The finished result should feel natural within the garden and in keeping with the property.
Many of our customers want a separate place to work, focus or create without giving up a room inside the house. A garden office or studio gives you that extra flexibility while keeping everything close to home.
We manage the full process from initial ideas and layout planning through to installation, keeping the job clear, organised and practical from start to finish.
We’ve been building garden rooms across Surrey for 10 years, with a strong focus on quality workmanship, professional service and aftercare that continues once the build is complete.

A garden room should feel like a genuine part of the way you live, not just an extra structure placed at the end of the garden. That’s why we start with how you want the room to function. Some homeowners want a garden office in Leatherhead so they can work quietly without taking over a bedroom or dining space. Others are looking for a studio, gym, hobby room or a flexible extra room that helps take pressure off the house.
The design has to work for both the property and the plot. In Leatherhead, that can vary quite a bit depending on whether you’re in Ashtead, Fetcham, Bookham, North Leatherhead or closer to the town centre. Some gardens are long and narrow, some sit on a slope, and others need careful positioning to make the most of privacy and natural light. Those details matter because they affect not just how the room looks, but how comfortable and practical it is to use all year round.
As experienced garden room builders in Leatherhead, we take care with all of that. We look at the structure, insulation, glazing, electrics, lighting and internal finish so the room feels solid, comfortable and properly thought through. The aim is always to create a space that works well in everyday life and still feels right years down the line.
We’ve spent the last 10 years installing garden rooms across Surrey, and that experience helps us keep projects straightforward and well managed. Customers want sensible advice, clear communication and workmanship they can rely on. That’s what we focus on.
We understand that homeowners in Leatherhead want a room that complements the property rather than feeling like an add-on. We also know that access can differ from one road to the next, especially in established residential areas where gardens, boundaries and neighbouring homes need to be considered carefully.
As a garden room installer in Leatherhead, we carry out our work professionally, keep the site tidy and make sure customers know where things stand throughout the build. We also place real value on aftercare. Once the project is finished, we’re still here if you need us.

1. We start with a conversation about your garden, your ideas and how you want the room to be used.
2. Next, we assess the layout, access and best position for the room so the design works well in practical terms as well as visually.
3. Once the design and specification are agreed, we carry out the garden room installation in Caterham in a tidy, organised and professional way.
4. When the build is complete, we walk you through everything properly and remain available for aftercare and any follow-up support.
We work throughout Leatherhead and across the wider Surrey area. That includes Fetcham, Ashtead, Great Bookham, Little Bookham, Mickleham, Oxshott, Epsom, Cobham and Dorking.
