A garden annexe is a smart way to add independent space for family, guests or a live-in carer while keeping everyone close. In BR2, we build high-spec, self-contained annexes that feel like a real home, not a glorified shed. Whether you’re near Shortlands station or closer to Beckenham, we tailor the layout around your garden and lifestyle. Expect proper insulation, secure doors and windows, plus compliant electrics and plumbing.
Shortlands is known for larger Edwardian houses, Victorian villas and well-proportioned 1930s properties—many with generous rear gardens ideal for an annexe. We design to suit period architecture, matching proportions, materials and rooflines so the new building sits comfortably with the main home. Access can be tight on some residential roads, so we plan deliveries and site logistics carefully. If you’re in Bromley, Ravensbourne or Bickley, we’ll advise on what works best for your plot and boundaries.
Fine Landscaping manages the full build: survey, design, groundworks, insulated structure, electrics, plumbing, and final finishes. You’ll get clear stages, a written scope, and tidy working practices to minimise disruption to neighbours. We coordinate inspections and provide planning support where required, keeping paperwork straightforward. Homeowners choose us for build quality, honest timelines and a finish that adds long-term value.
Across the London Borough of Bromley, ground conditions can vary, so we assess drainage and foundations before finalising the spec. Shortlands streets often have limited parking and narrow side access, so we schedule deliveries and protect paths, lawns and existing planting. We also consider neighbour sightlines and boundary constraints typical of BR2 plots. Our approach keeps the build compliant, considerate and practical for everyday living.

Costs in Shortlands typically range from £55,000–£120,000+ depending on size, specification and services. A compact studio-style annexe with a shower room usually sits at the lower end, while a larger one-bed with full kitchenette, higher-end finishes and more complex plumbing or electrics will be higher. Groundworks, access constraints and insulation/energy upgrades also affect the final figure.
Most garden annexes take around 8–14 weeks from start on site to completion, depending on complexity. Simpler designs with good access and straightforward groundworks can be quicker, while larger annexes with bathrooms, kitchenettes, bespoke glazing or tricky drainage runs take longer. Lead times for windows, doors and specialist finishes can also influence the programme. We provide a staged timeline before work begins.
Some garden buildings can be permitted development, but a self-contained annexe with sleeping, plumbing and a kitchenette often needs closer checks. In the London Borough of Bromley, rules can be affected by size, height, proximity to boundaries, and whether the space is classed as independent accommodation. We review your site, advise on the most compliant route, and provide planning support where an application is required.
We provide a 10-year warranty covering workmanship and the structural build elements of your garden annexe, giving you confidence long after handover. This includes key construction components and installation standards for the build itself. Manufacturer warranties apply to specific products such as windows, doors, electrical components and sanitaryware. We also carry out a completion walkthrough and address any snagging promptly.
You can choose from contemporary timber cladding, brick slips to echo period homes, or a clean rendered finish. Roof options include flat, mono-pitch or dual-pitch, with skylights for extra daylight. Internally, we can fit compact kitchenettes, walk-in showers, built-in storage and acoustic upgrades for privacy. We guide you through layouts and finishes to suit your garden, budget and how you’ll use the space in the garden annexes Shortlands area.
