Expect careful detailing, clean lines and a finish that stands up to British weather.
Sanderstead is known for large detached houses, executive homes and characterful period properties, and the right summer house should complement that quality. We design traditional styles with classic proportions, or contemporary designs with glazing and crisp cladding. Many clients want a quiet office, gym or hobby room that looks smart from the house and the patio. We also plan access and deliveries to suit long driveways, side passages and established planting.
We start with a site visit, measurements and a clear specification, then confirm foundations, insulation options and electrics before build begins. You’ll get straightforward scheduling, tidy working practices and workmanship backed by our 10-year warranty. Our joiners and landscapers coordinate the base, drainage and finishes so nothing is left to chance. Homeowners choose us for consistent communication and a result that feels properly built, not “flat-pack”.
As summer houses builders in London Borough of Croydon, we’re used to mixed ground conditions and gardens with level changes, especially around Sanderstead Plantation and the wider CR2 area. We specify the right base—concrete slab, ground screws or reinforced pads—based on soil, drainage and intended use. Access can be tight on some residential roads, so we plan deliveries, parking and waste removal to minimise disruption. The result is a build that suits Sanderstead’s high-value properties and mature landscapes.

Costs vary by size, specification and whether you want a simple garden retreat or a fully insulated room with electrics. As a guide, a small timber summer house with a proper base often starts around £6,000–£10,000. Mid-size bespoke builds with insulation, power and upgraded glazing are commonly £12,000–£25,000. Larger, high-spec garden rooms with premium finishes can be £25,000–£45,000+.
Most projects take 2–6 weeks from start on site, depending on the base type, complexity and internal fit-out. Foundations can take several days, especially if curing time is needed for concrete. The structure and weatherproofing typically follow within 1–2 weeks, with electrics and interior finishing adding time. Lead times for bespoke joinery, glazing and specialist cladding can also affect the overall schedule.
Many summer houses fall under permitted development, but it depends on height, location within the garden, overall footprint and whether it’s used as sleeping accommodation. Rules can also change for listed buildings or properties in restricted areas. We provide planning advice, check key limits and can help with drawings and submissions if needed. If building close to boundaries, we’ll also discuss neighbour considerations and practical access.
We provide a 10-year warranty covering workmanship and structural integrity of the build, including key elements such as the base preparation, framing and weatherproofing. Manufacturer warranties apply separately to products like doors, windows, membranes and electrical components. We document the specification and build stages so you know exactly what’s covered. If an issue arises, we respond promptly and arrange remedial work where it falls within warranty terms.
We offer traditional timber summer houses with classic detailing, or contemporary garden rooms with clean lines and larger glazing. Popular upgrades include insulated walls and roof, composite or cedar-style cladding, EPDM rubber roofing, and bifold or sliding doors. Inside, we can fit plasterboard, painted finishes, flooring, storage and lighting. We’ll help you choose materials based on maintenance preferences, budget, and how you plan to use the space year-round.
