A well-built summer house adds usable space without the upheaval of an extension—ideal for home working, hobbies or a quiet retreat. We design and build to suit Sydenham gardens, from compact plots near Bell Green to larger spaces by Sydenham Wells Park. Every build is planned around how you’ll use it, with options for insulation, electrics and interior finishing. Our team can also advise on the best placement for light, privacy and access.
Sydenham’s leafy streets and excellent period housing often come with established planting, mature trees and side access constraints. We regularly work with Victorian villas, Edwardian houses and period conversions across SE26, including nearby Forest Hill and Lower Sydenham. That experience helps us design structures that complement original brickwork, sash windows and traditional garden layouts. Where gardens are long and narrow, we’ll optimise footprint and roofline to keep the space feeling open.
We start with a site visit, measurements and a clear specification, then provide a detailed written quote and build schedule. Foundations, structure, electrics and finishing are coordinated so the project runs smoothly and safely. You’ll get practical planning advice, tidy working practices, and a build that’s made to last through British weather. Homeowners choose us for straightforward communication, careful workmanship and consistent quality control.
Gardens in Sydenham can vary from level lawns to sloping plots closer to Sydenham Hill Wood, so we specify the right base and drainage approach from day one. Access can be tight on streets with on-street parking, so we plan deliveries, waste removal and working hours to minimise disruption. We also factor in boundary lines, tree roots and neighbour considerations common in period gardens. If permissions are needed, we’ll guide you through London Borough of Lewisham expectations and documentation.

Costs depend on size, specification and groundworks. As a guide, a small, uninsulated timber summer house with a simple base often starts around £4,000–£7,000. Mid-range insulated builds with electrics and better glazing commonly fall between £8,000–£15,000. Larger, fully finished garden rooms with premium cladding, heating-ready insulation and bespoke interiors can be £16,000–£30,000+.
Most projects take 1–3 weeks on site, depending on foundations, size and finishing. A straightforward build with a prepared base can be completed in about a week, while insulated structures with electrics, plasterboard, flooring and joinery typically take longer. Timescales are affected by access, weather, lead times for bespoke doors/windows, and whether any ground levelling or drainage improvements are required.
Many summer houses fall under permitted development, especially when they’re single-storey, within height limits and positioned appropriately within the garden. However, rules can change for listed buildings, flats/maisonettes, conservation considerations, or if you want a larger footprint or raised base. We provide planning advice and can help you check constraints and prepare the right information before you commit to a design.
We provide a 10-year warranty on our workmanship for the structure and installation, covering issues such as fixings, alignment, weatherproofing details and general build integrity. Manufacturer warranties apply to specific components like doors, windows, membranes and cladding systems where relevant. We’ll explain what’s covered in writing, along with care guidance to keep timber and finishes performing well over time.
You can choose traditional timber styles with classic joinery, or contemporary designs with clean lines and modern cladding. Popular options include insulated walls/roof, double glazing, composite decking thresholds, plasterboard interiors, built-in storage and office-ready electrics. We’ll help you select materials based on appearance, maintenance level and year-round comfort, then tailor the layout around your intended use and available garden space.
