Eastfields homeowners are using garden space more creatively, from multigenerational living to quiet home-working. Our annexes are fully self-contained, with a bedroom area, bathroom and a practical kitchenette. We regularly work near Eastfields station and around Figges Marsh, so we understand access, neighbours and local expectations. The result is a premium finish that feels like a real extension of your home, not a temporary outbuilding.
The Eastfields area includes Victorian terraces, 1930s semis and newer developments across SW16 and CR4. Each property type brings different garden sizes, boundary lines and service routes for electrics and plumbing. We design garden annexes Eastfields area homeowners can use all year, with proper insulation, ventilation and efficient heating options. Whether you’re in Mitcham or Streatham Vale, we tailor the layout to maximise light, storage and privacy.
Fine Landscaping manages the full build: survey, design, groundworks, insulation, electrics, plumbing and interior fit-out. You’ll receive clear specifications, staged payments and a programme you can plan around. We also provide planning support, including guidance on permitted development and the documents typically requested. Being only 5 minutes away means responsive site visits and consistent quality control from start to finish.
Eastfields plots can be tight, with side access limitations and controlled parking on some streets. We plan deliveries, waste removal and working hours to minimise disruption, and we keep boundaries and drainage details precise. Ground conditions vary, so we specify suitable foundations and manage levels carefully to protect existing patios and lawns. Our experience across Pollards Hill and Lavender Park surrounds helps us design for privacy, sunlight and neighbour sightlines.

Costs vary with size, specification and how “self-contained” you need it to be. As a guide, a compact insulated annexe with electrics can start from around £35,000–£55,000. Adding a bathroom, kitchenette and higher-end finishes commonly brings projects into the £60,000–£110,000+ range. Groundworks complexity, drainage runs and bespoke glazing can increase budgets. We provide a detailed breakdown after a site survey in SW16/CR4.
Most builds take around 6–12 weeks on site once the design is agreed and materials are scheduled. Smaller, simpler annexes can be completed faster, while larger self-contained units with bathroom plumbing, kitchen fit-out and bespoke joinery take longer. Timescales are influenced by access, foundation requirements, utility connections and any lead times for windows and doors. We give you a realistic programme and keep you updated weekly.
Many garden buildings can fall under permitted development, but a self-contained annexe used as separate living accommodation can trigger extra rules. Limits on height, footprint, boundary distances and how the space is used all matter, and some properties have restrictions. We provide planning support, check the relevant guidance for the London Borough of Merton, and advise whether a lawful development certificate or full application is sensible before work begins.
We back our workmanship with a 10-year warranty covering the build structure and installation quality, giving you confidence that the annexe is made to last. This includes key construction elements such as framing, insulation installation, weatherproofing and internal finishes where workmanship is the cause. Manufacturer warranties also apply to many components, such as windows, doors and electrical products. We explain what’s covered in writing before the project starts.
You can choose from contemporary or more traditional designs to suit Victorian terraces, 1930s semis or modern homes. Popular options include timber or composite cladding, brick-slip detailing, flat or pitched roofs, and large sliding or bifold doors. Inside, we can fit compact kitchenette units, shower rooms, built-in storage and acoustic upgrades for home offices. We guide you through finishes, lighting and layouts to balance budget, durability and style.
