Elmers End homeowners are increasingly using the garden to create extra living space that works for family, guests or rental. Our annexes are designed to feel like a proper small home, not a glorified shed, with insulation, heating-ready electrics and full plumbing. If you’re near Elmers End station or along the Croydon Tramlink route, we’ll plan access and deliveries to keep disruption low. The result is a quiet, warm space you can use every day of the year.
The BR3 area has a mix of Victorian terraces, Edwardian houses and 1930s semis, each with different garden shapes and boundaries. We regularly design annex layouts to suit narrower plots and shared side access, common around Beckenham and Penge. For deeper gardens near South Norwood Country Park, we can position the annexe to protect light to the house and maximise privacy. Every build is tailored to your home’s character and the way you want to live.
We start with a site visit, measured survey and a clear scope covering foundations, insulation, electrics and plumbing. You’ll receive a practical layout, specification options and a staged programme, with planning support where needed. Our team manages the trades in-house and keeps neighbours considered, with tidy working and sensible hours. Local clients trust us because we communicate clearly, finish to a high standard and stand behind the work.
Across the London Borough of Bromley, gardens can vary from compact terrace plots to longer suburban plots behind 1930s semis. In Elmers End we plan around shared driveways, tight side returns and on-street parking, scheduling deliveries to avoid pinch points near Elmers End Green. We also consider drainage runs and falls so bathrooms and kitchenettes work reliably. Our designs respect neighbouring outlook and boundary lines, helping reduce objections and delays.
Rated 4.9/5 from over 280 verified reviews
Costs in Elmers End typically start around £45,000–£70,000 for a compact, insulated studio with a shower room. A larger, fully self-contained annexe with kitchenette, separate bedroom space, higher-end finishes and more complex plumbing/electrics is often £75,000–£120,000+. Price depends on size, foundations, access, specification, utility connections and whether you need extra soundproofing or bespoke glazing.
Most garden annexes take around 8–14 weeks on site once the design and specification are agreed. Simpler layouts with straightforward access can be quicker, while larger annexes with bathrooms, kitchenettes, bespoke joinery or tricky service runs can take longer. Timescales also depend on groundworks, weather, lead times for windows/doors and any planning or building control steps required before work starts.
Some garden buildings can fall under permitted development, but a self-contained annexe with sleeping and bathing facilities can trigger tighter rules, especially if it’s intended as a separate dwelling. In the London Borough of Bromley we check constraints such as conservation areas, height/position limits, boundary distances and how the annexe will be used. We provide planning support, drawings and guidance so you take the right route from the outset.
We provide a 10-year warranty on our garden annexe construction, covering workmanship and key build elements such as structure, insulation installation and weatherproofing. Manufacturer warranties apply separately to items like windows, doors, roofing membranes and electrical components. We also document the specification and handover checks, so you know what’s covered and how to maintain finishes. Any snagging issues are dealt with promptly and professionally.
We offer a wide range of options, from contemporary timber cladding to low-maintenance composite, plus brick or render finishes to suit period homes. Inside, you can choose compact kitchenette layouts, walk-in showers, underfloor heating readiness, acoustic upgrades and built-in storage. Popular glazing choices include sliding doors, corner glazing and rooflights for extra daylight. We guide you through choices based on budget, privacy, orientation and how you’ll use the space.
