Upper Norwood’s hilltop plots and generous gardens are ideal for a discreet, high-quality annexe that doesn’t compromise the main house. Whether you’re near Crystal Palace Park or closer to Westow Park, we design garden annexes that feel like a real home, not a shed. Expect proper insulation, secure doors and windows, and a layout that works for daily life. We can include a kitchenette, bathroom and bedroom to create a genuinely self-contained space.
We’re used to working around SE19’s period homes, from Victorian villas to Edwardian houses and well-managed conversions. These properties often have mature planting, side access constraints and heritage details worth protecting. Our designs respect existing sightlines and garden character, while upgrading practicality with modern electrics and plumbing. The result is an annexe that complements your property rather than competing with it.
From the first site visit to handover, we manage the build with clear schedules, tidy working and consistent communication. You’ll get guidance on foundations, insulation performance, drainage runs and electrical load, plus planning support where needed. We coordinate trades so plumbing, electrics and finishes align without delays. Local homeowners choose us because we deliver premium workmanship and stand behind it with a long warranty.
Upper Norwood’s sloping sites and mixed ground conditions can affect foundations and drainage falls, so we survey carefully before finalising designs. Access can be tight on residential streets, with controlled parking and limited turning space, so we plan deliveries and waste removal to minimise disruption. We’re familiar with expectations in the London Borough of Croydon and can advise on neighbours, boundaries and overlooking. If your garden sits near mature trees, we’ll factor root protection and long-term movement into the build.
Rated 4.9/5 from over 280 verified reviews
For Garden Annexes in Upper Norwood, most homeowners budget from around £45,000–£90,000 for a well-finished, insulated annexe with electrics and basic plumbing. Larger footprints, premium glazing, higher-end kitchens/bathrooms, and complex groundworks can push costs to £100,000–£150,000+. Final pricing depends on size, spec, access, drainage runs and whether you need a full bathroom and kitchenette.
A typical build takes 8–14 weeks on site once the design and specification are agreed. Smaller, simpler annexes can be completed sooner, while larger self-contained layouts with bathroom, kitchenette, and bespoke joinery often take longer. Timescales are influenced by ground conditions, service connections (water, waste and electrics), lead times for windows/doors, and any planning or building control requirements.
Many garden outbuildings can fall under permitted development, but a self-contained annexe, its intended use, height, boundary distances and location can change what’s allowed. In the London Borough of Croydon, restrictions may also apply for flats, conversions, or where previous permissions removed permitted development rights. We provide planning support, check constraints, and help prepare drawings and information so you can proceed with confidence.
We provide a 10-year warranty covering structural workmanship and key build elements, giving you long-term peace of mind. This includes the integrity of the main structure, insulation installation, and weatherproofing details when built to our specification. Manufacturer warranties also apply to many components such as windows, doors and electrical products. We’ll explain what’s covered, what maintenance is required, and how to log any issues.
We tailor annexes to your garden and budget, with popular options including contemporary timber cladding, low-maintenance composite finishes, or brick slips to echo period homes. Inside, you can choose compact kitchenette layouts, full shower rooms, built-in storage, and different heating solutions. Glazing can range from large sliders to more private window arrangements. We guide you through finishes, durability and energy performance to match how you’ll use the space.
