A well-built summer house adds year-round space for work, hobbies or entertaining, without changing the character of your garden. We design and build structures that sit comfortably alongside Dulwich’s distinctive architecture, from Dulwich Village to East Dulwich. Whether you want views over planting or privacy screening, we’ll shape the layout around how you use the garden. Many of our clients are within easy reach of Dulwich Park and SE21–SE24.
Dulwich homes often come with generous plots, side access constraints, and period details worth respecting. We regularly work with Georgian and Victorian houses, plus larger detached properties in West Dulwich and Herne Hill. Our designs can echo existing sash-window proportions and rooflines, or introduce clean contemporary cladding that complements brickwork. Every build is measured precisely to make the most of space while keeping sightlines and boundaries in mind.
We start with a site visit, discuss use (office, gym, studio, guest space), then provide a clear specification and schedule. Foundations, insulation options, electrics and interior finishing are planned upfront so there are no surprises later. Our team keeps the site tidy, protects lawns and paving, and communicates progress throughout. Homeowners choose us for dependable workmanship, transparent pricing, and a finish that feels truly bespoke.
As summer houses builders in London Borough of Southwark, we plan builds around local access and parking realities, especially on narrower streets near Dulwich Village and SE22. Ground conditions vary between gardens, so we assess drainage, levels and tree roots before specifying foundations. We also consider neighbouring boundaries, privacy, and typical rear-garden layouts found in Victorian terraces. Where needed, we guide you through Southwark’s expectations for size, height and placement.

Costs in Dulwich vary by size, specification and access. As a guide, a small, uninsulated summer house can start from around £6,000–£10,000. Insulated garden rooms with electrics, better glazing, and higher-end internal finishes are commonly £12,000–£25,000+. Larger bespoke builds with premium cladding, heating, and custom joinery can exceed £30,000. We provide a detailed breakdown after a site survey.
Most projects take 2–6 weeks from start on site, depending on groundworks, design complexity and finishing. A straightforward base and pre-designed structure may be completed in around 2–3 weeks. Bespoke builds with insulation, electrics, plastering, flooring and joinery typically take longer. Timescales are also affected by access (side passages), weather, and lead times for doors, windows and cladding materials.
Many summer houses fall under permitted development, provided they meet limits on height, footprint, placement and use (for example, not as a separate dwelling). However, rules can change depending on whether your property is listed, in a conservation area, or has previous planning conditions. We offer planning advice, check the key constraints, and can help you prepare information for Southwark if an application or lawful development certificate is sensible.
We provide a 10-year workmanship warranty on our summer house builds, covering installation quality and construction defects related to our work. This includes key elements such as the base/foundations, structural framing, and weatherproofing details. Manufacturer warranties apply separately to products like doors, windows, membranes and electrical components. We also give clear maintenance guidance to help timber finishes and seals perform well over time.
You can choose traditional timber styles (tongue-and-groove, painted finishes) or contemporary designs with clean lines and modern cladding. Popular upgrades include insulation packages, double glazing, integrated electrics and lighting, and refined interior finishing such as plasterboard, oak-effect flooring or built-in storage. Roof options can be felt, EPDM, or more architectural profiles where suitable. We’ll recommend the best combination based on your garden, budget and intended use.
