A garden room gives you the extra space you need for work, hobbies or family time, without sacrificing your home’s layout. We build bespoke rooms across Sutton, including Cheam and Carshalton, with designs that suit both compact and generous gardens. Whether you’re near Sutton High Street or closer to Manor Park, we’ll tailor the footprint, glazing and finish to your lifestyle. Every build is fully insulated for comfortable use in all seasons.
Homes in Sutton range from Victorian terraces to 1930s semis and newer developments, and each brings different access and design considerations. We’re used to side passages, shared drives and established planting that needs protecting during construction. In SM1, SM2 and SM3 we often match materials to existing brickwork, render or cladding so the new room feels like it belongs. If you want a discreet garden office or a statement studio, we’ll design around your property’s character.
Our process starts with a site visit, measured survey and clear specification, followed by a detailed quote and programme. We handle groundwork, electrics, insulation, doors and windows, plus the internal finish so you can move straight in. You’ll have a dedicated point of contact, tidy working practices, and regular progress updates. Fine Landscaping is based just 20 minutes away, so support is close by throughout the build and aftercare.
Sutton gardens often have mature trees, clay-heavy ground and tight access routes, especially around older streets in Cheam and Benhilton. We plan foundations and drainage to suit site conditions and protect existing patios, lawns and borders. Parking and deliveries can be tricky near Sutton High Street, so we schedule materials to minimise disruption. Where council constraints apply, we’ll advise early and keep the design compliant.

Most garden rooms we build in Sutton fall between £15,000 and £25,000, with an overall range of £10,000–£40,000 depending on size and specification. Costs are influenced by insulation levels, glazing, electrics, heating, and internal finishes. Ground conditions and access can also affect the budget, particularly for larger bases or more complex foundations. We provide a detailed breakdown so you can compare options confidently.
A typical garden room build takes 2–4 weeks from start on site, depending on the footprint and finish. Groundworks and the base usually come first, followed by the structure, insulation, doors/windows and electrics, then internal lining and final detailing. Timescales can change if access is restricted, if you choose bespoke joinery, or if weather delays groundwork. We agree a programme before work begins and keep you updated throughout.
Many garden rooms can be built under permitted development, provided they meet limits on height, placement and overall garden coverage. However, rules can differ for listed buildings, flats, maisonettes, or homes in conservation areas, and outbuildings used as sleeping accommodation may need additional consent. We’ll review your site in Sutton, check the relevant guidance, and recommend the safest route. If permission is needed, we can support with drawings and information.
We provide a 10-year warranty covering workmanship and key build elements, giving you confidence that your garden room will perform as intended. This includes the structure, insulation installation and weatherproofing details, provided the room is used and maintained appropriately. Manufacturer warranties also apply to many components such as doors, windows and certain cladding systems. We’ll explain what’s covered in writing and remain available for aftercare if you have questions.
You can choose from contemporary or traditional designs, with options such as composite cladding, timber cladding, render finishes and high-performance glazing. Inside, popular choices include plastered walls, acoustic upgrades for offices or studios, and durable flooring for gym rooms. We can add skylights, bi-fold or sliding doors, and tailored lighting and power layouts. We’ll help you balance looks, maintenance and budget so the room suits your garden and how you’ll use it.
