If you want more space near Lordship Lane or close to Dulwich Park, a garden annexe can be the smartest upgrade you make. Our annexes are fully self-contained, with a bedroom, bathroom and kitchenette so they work as genuine living accommodation. We handle insulation, electrics and plumbing as part of a coordinated build. The result is a comfortable, private space that feels like a natural extension of your home in SE22.
East Dulwich homes often come with generous gardens behind Victorian terraces and Edwardian houses, plus period conversions where every square metre matters. We’re used to working around side returns, narrow access routes and established planting, keeping disruption low and finishes high. Whether you’re in Peckham Rye, Dulwich Village or nearby Nunhead, we tailor layouts to suit your plot and privacy needs. Expect thoughtful detailing that complements period architecture while meeting modern performance standards.
We start with a site visit, clear measurements and a practical design that balances budget, daylight and storage. You’ll get a written scope, staged programme and a single point of contact from groundwork to final fix. Our team coordinates trades so electrics, plumbing, insulation and fit-out run smoothly. Local homeowners choose Fine Landscaping for tidy sites, dependable timelines and workmanship backed by a 10-year warranty.
Across the London Borough of Southwark we often encounter clay-heavy ground, mature tree roots and tricky rear access behind terraces. Parking and delivery slots around SE22 can be tight, so we plan logistics and keep materials secure and tidy. We also design to respect neighbouring sightlines, which matters in closely spaced gardens near Peckham Rye and Herne Hill. Our approach keeps your build compliant, considerate and efficient.




Rated 4.9/5 from over 280 verified reviews
For East Dulwich projects, a high-quality, self-contained garden annexe typically starts around £45,000–£70,000 for a compact studio-style layout. Larger annexes with a separate bedroom, premium glazing, higher-spec kitchenette and bathroom often fall in the £75,000–£120,000+ range. Costs vary with size, foundations, access, insulation levels, and the complexity of electrics and plumbing connections. We provide a detailed, itemised estimate after a site survey.
Most garden annexes take around 8–14 weeks on site once designs are agreed and materials are ordered. Simpler, smaller builds can be quicker, while larger annexes with bespoke joinery, complex plumbing runs or upgraded insulation and finishes can take longer. Timescales are also affected by access through narrow side passages, ground conditions, and any required inspections. We give you a realistic programme and keep you updated at each stage.
Some garden buildings can be built under permitted development, but a self-contained annexe with sleeping and bathing facilities can trigger extra rules, especially if it’s intended as separate accommodation. In the London Borough of Southwark, constraints like conservation areas, listed buildings, height limits, and proximity to boundaries may also apply. We provide planning support, advise on the best route, and can liaise with the council to confirm what’s required before work begins.
We provide a 10-year warranty covering structural workmanship and core build elements, giving you long-term confidence in the annexe. This includes the integrity of the main structure, weatherproofing, insulation installation and general construction quality. Manufacturer warranties apply separately to items such as doors, windows, roofing membranes, electrics components and appliances. We also complete snagging and aftercare checks so the space performs as intended through every season.
We offer a range of design routes, from contemporary timber-clad annexes to crisp rendered finishes that suit period gardens. Popular options include aluminium or timber windows, sliding or bifold doors, green roofs or high-performance flat roofs, and underfloor heating or panel heating. Inside, we can fit compact kitchenette runs, walk-in showers and built-in storage. We guide you through layouts, specifications and samples to match your budget and the style of your home.
