Nunhead homeowners often want extra space without moving, especially around SE15 where gardens can be a real asset. A well-built garden annexe creates a private, self-contained place for family, guests or rental use. We regularly work near Nunhead Cemetery and Telegraph Hill Park, so we understand the mix of plot sizes and access constraints. Our annexes can include a kitchenette, bathroom and bedroom, finished to a high, residential standard.
The Nunhead area is known for Victorian terraces, Edwardian houses and period cottages, each with different garden levels and boundary conditions. We design annexes that suit these properties, keeping proportions sympathetic and sightlines considered. Whether you’re in Peckham, Brockley or East Dulwich, we’ll plan layouts that make the most of light, privacy and storage. Every build is insulated for comfortable, low-energy use throughout the year.
Fine Landscaping manages the full build: groundwork, foundations, structure, insulation, electrics and plumbing. You’ll get clear specifications, a staged programme and tidy working practices that respect neighbours and shared access. We also provide planning support, advising on permitted development and when an application is the safer route. Local homeowners choose us for dependable timelines, consistent workmanship and a finish that feels like part of the home.
Gardens in Nunhead can have level changes, mature planting and narrow side access, especially behind terraces near Nunhead Green. We plan deliveries, parking and waste removal to minimise disruption on residential streets. Our designs consider boundary distances, overlooking and drainage so the annexe works practically in the garden. For garden annexes in London Borough of Southwark, we also guide you through local planning expectations and documentation.
Rated 4.9/5 from over 280 verified reviews
In Nunhead, garden annexes typically start around £45,000–£70,000 for a compact, well-finished studio-style build. A larger, fully self-contained annexe with a separate bedroom, kitchenette, bathroom, higher-spec glazing and more joinery often falls between £80,000–£140,000+. Ground conditions, access, utility connections, and the level of internal finishes have the biggest impact on the final budget.
Most builds take around 8–14 weeks on site once designs, specifications and start dates are agreed. Simpler footprints with straightforward utility runs can be quicker, while larger annexes with bathrooms, kitchenettes, bespoke glazing or complex groundwork take longer. Lead times for windows, cladding and internal finishes can also affect the programme. If planning approval is needed, allow additional time for the council process.
Some garden buildings can be permitted development, but a self-contained annexe used as independent accommodation often triggers extra rules. In the London Borough of Southwark, factors like height, proximity to boundaries, intended use, and whether the property is in a constrained area can all matter. We provide planning support by checking constraints, advising on the safest route, and preparing the information needed for an application when required.
We provide a 10-year warranty covering workmanship and the structural elements of your garden annexe, giving you confidence long after completion. This includes key build components such as the main structure, weatherproofing details and installation quality. Manufacturer warranties apply separately to items like windows, doors, cladding systems and electrical components. We also hand over documentation for certifications and provide aftercare guidance for ongoing performance.
Design options range from contemporary garden rooms with large sliding doors to more traditional forms that suit Victorian and Edwardian homes. Popular external finishes include timber cladding, composite boards, brick slips and rendered systems, paired with flat or pitched roofs. Internally, we can fit compact kitchenettes, full bathrooms, built-in storage and efficient heating/ventilation.
