Norwood Grove homeowners often want extra space that works year-round, not a summer-only garden room. Our annexes are built as self-contained accommodation with insulation, electrics and plumbing, plus a bedroom, bathroom and kitchenette if required. Whether you’re near Norwood Grove Park or closer to Upper Norwood Recreation Ground, we design to suit plot size, access and privacy. The result is a comfortable, compliant space for family, guests or rental use.
The Norwood Grove area includes Victorian houses, Edwardian properties and period conversions, each with different garden levels and boundary details. We’re used to working with tight side access, shared drives and established planting typical around Upper Norwood and Crystal Palace. Our designs respect existing brickwork, sash-window proportions and traditional garden layouts while adding modern performance. We can match cladding and rooflines to complement your home rather than compete with it.
From the first site visit to handover, you get a clear scope, staged programme and tidy working practices. We manage groundworks, foundations, insulation build-up, electrics and plumbing, and coordinate finishes so the annex is ready to use. You’ll also receive planning support, including guidance on permitted development and when a full application is sensible. Local homeowners choose us for reliable communication, detailed workmanship and a finish that lasts.
Across the London Borough of Croydon, gardens in SE19 can vary from flat terraces to sloping plots near Beaulieu Heights. We plan foundations and drainage to suit local ground conditions and manage rainwater properly. Access and parking can be limited on residential roads, so deliveries and waste removal are scheduled to minimise disruption. We also factor in neighbour boundaries, overlooking and council expectations from the outset.

For garden annexes Norwood Grove area projects, costs commonly start around £45,000–£70,000 for a well-insulated studio with electrics. A larger, fully self-contained annexe with bathroom, kitchenette and higher-end finishes is often £80,000–£140,000+. Price depends on size, specification, groundworks, access, glazing, and the level of fit-out (flooring, tiling, kitchen units and heating). We provide an itemised estimate after a site survey.
Typical build times are 6–12 weeks from start on site for most annexes, with simpler studio-style builds sometimes quicker. Larger self-contained units with bathroom and kitchenette can take 10–16 weeks, especially where groundworks are complex. Timescales depend on design approvals, lead times for windows/doors, utility connections, and site access. We set a clear programme and keep you updated at each stage.
Some garden buildings can be permitted development, but a self-contained annexe used as separate accommodation may trigger planning requirements. In the London Borough of Croydon, rules can also be affected by height, proximity to boundaries, total garden coverage, and whether your property is a flat or conversion. We provide planning support, check constraints, and advise on the most practical route—permitted development where possible, or a full application when needed.
We provide a 10-year warranty covering structural workmanship and key build elements, giving you long-term confidence in the annexe. This includes the integrity of the main structure, insulation build-up and weatherproofing when installed by our team. Manufacturer warranties apply separately to products such as windows, doors, electrics components and sanitaryware. We also carry out a handover check and address any snagging promptly.
