A garden annexe is a practical way to gain extra living space without moving—ideal for multigenerational living, a home office that feels separate, or guest accommodation. In Bermondsey, we design annexes that suit compact plots and urban gardens while staying comfortable year-round. We regularly work around access constraints near London Bridge and SE1 streets. Expect a self-contained build with insulation, electrics, plumbing, and high-quality finishes.
Bermondsey’s mix of converted warehouses, Victorian terraces and modern apartments means no two gardens are the same. We tailor layouts to long, narrow terrace gardens and courtyards, and we’re experienced with boundary lines and party-wall considerations where homes sit close together. For properties around SE16 and Rotherhithe, we often design annexes that maximise light while protecting privacy. The result is a space that looks intentional, not like an afterthought.
Our process starts with a site survey, concept design and a clear specification, then we coordinate trades for foundations, structure, electrics and plumbing. You’ll get straightforward timelines, tidy working practices, and regular updates from a dedicated project lead. We also provide planning support and guidance on Building Regulations where required. Homeowners choose us for workmanship you can see, and aftercare you can rely on.
Bermondsey sites often involve restricted access, controlled parking, and neighbours close by—especially around Bermondsey Street and Tower Bridge approaches. We plan deliveries, waste removal and working hours to reduce disruption and keep projects moving. Ground conditions can vary with made ground and old hardstanding, so we assess drainage and foundations carefully. If permissions are needed, we help you navigate London Borough of Southwark requirements with clear documentation.

Costs vary with size, specification and services, but most homeowners in the Bermondsey area budget from around £45,000–£90,000 for a fully insulated, self-contained annexe with electrics and plumbing. Higher-end builds with premium glazing, bespoke joinery, larger footprints, or complex groundwork can reach £100,000–£140,000+. We provide an itemised estimate after a site survey, so you can see where the budget goes.
A typical build takes around 8–14 weeks on site once designs are agreed, depending on size and complexity. Simple, smaller annexes can be quicker, while projects needing more groundwork, drainage changes, or bespoke interiors take longer. Lead times for windows, cladding and bathroom/kitchen finishes can also affect the schedule. If planning or Building Regulations input is required, allow extra time before work starts.
Some garden buildings can fall under permitted development, but a self-contained annexe with sleeping and bathroom facilities can trigger additional planning considerations in Southwark. Restrictions may apply due to height, proximity to boundaries, conservation areas, or how the annexe will be used. We review your site, advise on the safest route, and provide planning support where needed. We also flag Building Regulations requirements early, so there are no surprises.
We provide a 10-year warranty covering structural workmanship and installation quality, giving you long-term confidence in the build. This includes key elements such as the main structure, insulation installation, and weatherproofing details when installed by our team. Manufacturer warranties apply separately to items like windows, doors, roofing membranes, and appliances. We also offer aftercare support, so minor snagging can be resolved promptly once you move in.
You can choose from contemporary or traditional styles, with popular options including timber or composite cladding, brick-slip finishes, and aluminium or uPVC glazing. Inside, we can fit a compact kitchenette, shower room, built-in storage and a flexible bedroom/living layout. Heating options include electric panel heaters or underfloor systems, with ventilation specified for year-round comfort. We guide you through choices that suit your garden, budget and the look of your home.
