A well-designed garden room gives you extra space that feels like part of the house, but with the calm of the garden. We build bespoke rooms across Streatham Hill and Streatham Common, with layouts that suit home working, hobbies or entertaining. Whether you’re near Streatham Common or closer to Streatham High Road, we’ll design a room that fits your plot and lifestyle. Expect clean lines, durable materials and a finish that stands up to South London weather.
Streatham’s mix of Victorian and Edwardian houses, mansion flats and newer apartments often comes with long gardens, shared boundaries and varied access. We regularly work on narrow side returns, stepped plots and gardens that need careful protection of paving and planting. In SW16 and SW2, we tailor foundations and drainage to the conditions on site and the way your garden is used. The result is a garden room that feels considered, not squeezed in.
From the first survey to final handover, you’ll have a clear plan, fixed scope and tidy working practices. We handle design, insulation specification, electrics coordination and internal finishes, with regular updates throughout. Our team is based just 10 minutes away, so aftercare is straightforward and responsive. Homeowners choose us for consistent workmanship, transparent costs and a build that stays on programme.
We’re used to Streatham’s mixed property styles and the practicalities of working on busy residential streets. Access and parking can be tight near Streatham High Road, so we plan deliveries and waste removal carefully. Gardens around Streatham Common and Rookery Gardens can include mature trees and root zones, which we factor into foundations and drainage. We also check London Borough of Lambeth requirements and advise on what’s likely to be permitted.

Broader budgets typically range from £10,000 to £40,000 depending on size, glazing, cladding choice, heating, bathroom/kitchenette needs and groundworks.

A typical build takes 2–4 weeks from breaking ground to final finish, depending on specification and site access. Larger rooms, complex groundworks, bespoke glazing, and additional fit-out (such as a WC, kitchenette or acoustic upgrades for music use) can extend the programme. Weather and delivery lead times for premium cladding or doors can also affect scheduling. We confirm a realistic timeline before work starts.
Many garden rooms in London Borough of Lambeth can be built under permitted development, provided they meet limits on height, placement and use (for example, ancillary to the main home rather than a separate dwelling). However, rules can vary with conservation considerations, previous extensions, and proximity to boundaries. We’ll review your site, flag any likely constraints and recommend whether a lawful development certificate or planning application is sensible.
We provide a 10-year warranty covering workmanship and the structural build of your garden room, giving you confidence it will perform year after year. This includes key elements such as the base, framing, insulation installation, weatherproofing and external cladding fit. Manufacturer warranties apply separately to products like doors, windows, membranes and electrical components. We also offer practical aftercare if you need adjustments once you’ve moved in.
You can choose from contemporary or classic designs, with popular options including timber or composite cladding, aluminium or uPVC glazing, and flat or mono-pitch roofs.

We guide you through choices based on budget, maintenance preferences and how you’ll use the space.
