Chelsea gardens deserve buildings that look as considered as the homes around King’s Road. We design and construct premium summer houses that work for relaxing, entertaining or a quiet home office. Whether you’re near Stamford Bridge or closer to the Saatchi Gallery, we plan access and installation to minimise disruption. Every build is made to measure, with options for electrics, insulation and high-end interior finishing.
Our team regularly works across SW3 and SW10, where outdoor space can be compact and boundaries are close. We’re used to the constraints of Georgian townhouses, Victorian mansions and luxury apartments with landscaped courtyards. That means careful positioning for light and privacy, and designs that complement period brickwork or contemporary façades. If you’re in South Kensington, Knightsbridge or Pimlico, we’ll tailor the build to your property’s character and garden layout.
We start with a site visit, measurements and a clear design proposal, then confirm foundations, drainage considerations and cable routes before work begins. You’ll get practical planning advice, a defined schedule and workmanship backed by our 10-year warranty. Our installers keep the site organised, protect paving and planting, and complete a clean handover with electrics tested and finishes signed off. Homeowners choose us for reliable communication and a build that looks premium from day one.
Chelsea sites often involve narrow side access, controlled parking and strict neighbour considerations. We plan deliveries, waste removal and working hours to suit the Royal Borough of Kensington and Chelsea. Ground conditions can vary between older made ground and compacted garden soils, so we specify the right foundation type after inspection. Our designs also respect local streetscapes, especially around period terraces and listed-adjacent properties.

Costs vary with size, specification and access. As a guide, a small bespoke summer house with solid base and basic interior finishing often starts around £6,000–£10,000. Mid-size builds with insulation, upgraded cladding and electrics commonly fall in the £12,000–£25,000 range. Larger garden rooms with premium glazing, higher-end interiors and complex foundations can be £25,000–£45,000+. We provide a detailed, itemised quote after a survey.
Most projects take 2–6 weeks from start on site, depending on groundwork, size and finishing level. Foundations and base preparation typically take several days, with the main structure following soon after. Electrics, insulation and interior finishing add time, particularly if you want plasterboard, built-in storage or feature lighting. Access restrictions in SW3/SW10, bespoke joinery and wet weather can also affect the programme.
Many summer houses fall under permitted development, but it depends on height, footprint, placement near boundaries and whether the property is listed or in a conservation area. In parts of the Royal Borough of Kensington and Chelsea, extra constraints can apply, so it’s important to check before ordering materials. We provide planning advice, review the rules for your site, and can help with drawings and submissions if permission is required.
We provide a 10-year warranty on workmanship for your summer house build, covering structural installation, fixings, base preparation and fit-out completed by our team. Manufacturer warranties apply separately to items such as doors, windows, cladding systems and electrical components. We also offer clear care guidance for timber treatment, ventilation and ongoing maintenance. If an issue arises, we respond promptly and arrange inspections and remedial work where needed.
You can choose from traditional timber summer houses, contemporary garden studios, or hybrid designs that suit Georgian and Victorian properties. Popular options include cedar or treated softwood cladding, composite finishes, double-glazed doors, EPDM or felt roofing, and insulation upgrades for year-round comfort. We can install electrics for lighting, sockets and heating, plus interior finishing such as panelling, plasterboard or built-in storage. We’ll recommend choices based on style, budget and how you’ll use the space.
