A well-built summer house adds practical space for work, hobbies or hosting—without changing your home. We create bespoke designs that suit Sevenoaks gardens, from traditional timber styles to crisp contemporary lines. Whether you’re near Knole House or closer to Riverhead, we plan the layout around light, privacy and access. Every build is finished with details that make it comfortable to use year-round.
Sevenoaks is known for large detached houses, period properties and executive homes, and the garden building needs to match that standard. We regularly work across TN13 and TN14, designing structures that complement mature planting, patios and pool areas. For character homes, we can echo classic proportions and joinery; for newer properties, we’ll keep it clean and architectural. If you want a garden office, gym or studio, insulation and electrics can be specified from day one.
We start with a site visit, measurements and a clear design proposal, then confirm foundations, drainage considerations and the build programme. You’ll get planning advice where needed, plus guidance on insulation options, internal lining and power/lighting layouts. Our team keeps the site tidy and coordinates deliveries to minimise disruption on residential streets. Homeowners choose us for dependable communication, premium workmanship and a finish that lasts.
Across the Sevenoaks District we often encounter sloping plots, mature tree roots and restricted side access, especially around older homes. We plan base construction and material deliveries to suit driveways, parking rules and narrow gates, and we’ll advise if a crane or sectional build is sensible. Ground conditions vary, so we choose the right foundation approach for stability and drainage. If you’re in Dunton Green, Otford or TN15, we’ll tailor the design to your plot and neighbours’ sightlines.

Costs vary with size, specification and access. As a guide, a small, uninsulated summer house can start from around £6,000–£10,000. Mid-sized insulated garden rooms with electrics and better glazing are commonly £12,000–£25,000. Larger bespoke builds with premium cladding, multiple rooms, heating and higher-end interiors can be £25,000–£45,000+. We’ll provide a detailed, itemised estimate after a site visit.
Most projects take 2–6 weeks from start on site, depending on complexity. A straightforward build with a simple base and standard finish may be completed in around 10–15 working days. Bespoke designs with insulation, electrics, internal lining, bespoke joinery and painted finishes take longer. Timescales are also affected by groundworks, access for materials, weather, and lead times for doors, windows and cladding.
Many summer houses fall under permitted development, provided they meet limits on height, placement and how much of the garden is covered. However, rules can change for listed buildings, conservation areas, or if the structure is used as separate accommodation. We give practical planning advice and can help you check requirements with Sevenoaks District Council before work begins. If permission is needed, we’ll support drawings and specification details.
We provide a 10-year warranty covering workmanship and structural integrity of the build, including the base/foundations and main construction elements, when installed and maintained as advised. Manufacturer warranties apply to specific products such as doors, windows, membranes and electrical components. We also complete a thorough handover and snagging process so finishes, seals and fittings are right. If an issue arises, you’ll have a clear point of contact.
We offer traditional styles (tongue-and-groove timber, classic joinery, felt or shingle roofs) and contemporary designs (clean lines, composite or larch cladding, large glazing). Insulation options include floor, wall and roof systems to suit year-round use, plus electrics for lighting, sockets and data. Inside, choose painted timber, plasterboard and skim, feature cladding, built-in storage and durable flooring. We’ll recommend options based on your garden, budget and intended use in the sevenoaks area.
