If you need more room at home but don’t want the disruption of moving or extending, a garden room can be a practical way to create extra space without changing the way your house works. At OuterRoom, we design and build garden rooms in Walton-on-Thames that are made to suit the property, the garden and how you want to use the space day to day.

Every garden has its own layout, access and character, so we build each room around the space available. Whether you want something sleek and modern or a design that sits more quietly within the garden, we’ll tailor it properly.
Many homeowners come to us because they need a separate place to work, create or focus. A garden office or studio gives you privacy and flexibility without needing to leave home.
We take care of the full journey, from the first ideas and layout planning through to the final installation, keeping everything clear and well organised along the way.
We’ve been building garden rooms across Surrey for 10 years, with a strong focus on quality workmanship, a professional service and the sort of aftercare that matters once the room is in use.

A good garden room should feel like part of the home, even though it sits separately from it. That means it needs to be well designed, comfortable to use and built with real everyday use in mind. Some of our customers want a garden office in Walton-on-Thames so they can work in peace without taking over the spare bedroom. Others want a studio, a gym, a treatment room or simply somewhere flexible that gives the household more breathing space.
We start by looking at how the room will be used, then shape the design around that. The size, layout, finish and position in the garden all make a difference. In Walton-on-Thames, that can vary quite a bit depending on whether the property is closer to Ashley Park, around Hersham Road, near the centre, or out towards Burwood Park and neighbouring areas. Some gardens are long and narrow, others are wider but need careful positioning to keep the room feeling balanced within the plot.
As a garden room installer in Walton-on-Thames, we focus on getting those practical details right. That includes insulation, lighting, electrics, access and the overall finish, so the room doesn’t just look good on day one but continues to work well in the years ahead.
We’ve spent the last 10 years building garden rooms across Surrey, and that experience helps us keep projects straightforward and well managed. Customers usually want the same things: honest advice, clear communication, tidy workmanship and a finished room that feels solid and well considered.
We understand the expectations that come with homes in Walton-on-Thames. People want a room that complements the property rather than feeling like an afterthought. They also want to know the work will be carried out professionally, with sensible planning and respect for the garden and surrounding area.
As garden room builders in Walton-on-Thames, we take pride in the quality of our work and the aftercare we provide. We’re not just there for the build itself. We want you to feel confident in the finished room and comfortable coming back to us if you need anything afterwards.

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 Walton-on-Thames and across the wider Surrey area. That includes Ashley Park, Ambleside, Rydens, Hersham, Sunbury, Molesey, Weybridge, Byfleet and Esher.
