A garden annexe is a smart way to add independent living space without changing your main home layout. In Shirley (CR0), we build fully self-contained annexes that work for family, guests, or long-term rental. Many homeowners near Shirley Windmill and Shirley Park Golf Club want a quiet, private space that still feels connected to the house. We tailor the footprint, access and finishes to suit your garden and lifestyle.
The Shirley area includes plenty of 1930s semis, detached houses and newer developments, each with different garden sizes and access routes. We regularly work across Addiscombe, Addington and West Wickham, so we understand typical boundary lines, shared drives and rear access challenges. Whether you need a compact studio annexe or a larger one-bedroom layout, we design around your plot and existing services. The result is a comfortable, insulated building that looks like it belongs with the property.
Fine Landscaping manages the full journey: survey, design, groundworks, build, electrics, plumbing and final fit-out. You’ll get clear specifications, staged payments and a tidy site, with practical advice on planning support from day one. We use durable materials and build for year-round comfort, not seasonal use. With our base just 15 minutes away, you can expect responsive communication and dependable aftercare.
Shirley gardens often have level lawns but variable drainage, so we specify bases and soakaway solutions carefully. Access can be tight on some CR0 streets, with shared driveways and limited parking, so deliveries and waste removal are planned to minimise disruption. We also factor in neighbouring sightlines and boundary constraints common around Addiscombe and Addington. Where needed, we support you with the London Borough of Croydon planning approach and documentation.




Rated 4.9/5 from over 280 verified reviews
Costs in Shirley typically range from £45,000–£90,000+ depending on size, specification and the level of fit-out. A compact, self-contained studio with kitchenette and shower room is usually at the lower end, while a larger one-bedroom annexe with higher-end finishes, extra glazing and upgraded insulation sits higher. Ground conditions, service connections (electrics/plumbing) and access for machinery can also affect the budget.
Most garden annexes take around 8–14 weeks from groundworks to completion once designs and specifications are agreed. Simpler footprints and straightforward service runs can be quicker, while larger annexes with bathrooms, kitchenettes and bespoke joinery take longer. Timescales are also influenced by access, weather during base works, and lead times for windows, doors and specialist finishes. We provide a clear programme before work starts.
Some garden buildings can fall under permitted development, but a self-contained annexe with sleeping, bathroom and kitchenette often needs closer checking. Rules can vary depending on height, proximity to boundaries, intended use, and whether the property has restrictions. In the London Borough of Croydon, we review your site, advise on the safest route, and provide planning support where needed. We’ll flag constraints early to avoid delays.
We provide a 10-year warranty covering workmanship and key construction elements, including the structure, insulation build-up and weatherproofing when installed as specified. Individual components such as electrics, plumbing fittings, boilers or heaters may also carry their own manufacturer warranties. We document what’s included, so you know exactly what’s protected. If any issues arise, our local team can respond quickly and put things right.
We offer a wide range of options, from contemporary timber cladding to low-maintenance composite finishes, plus brick slips to complement traditional homes. Internally, you can choose layouts with open-plan living, a separate bedroom, or accessible bathroom arrangements. Popular upgrades include underfloor heating, acoustic insulation, rooflights and sliding doors. We guide you through choices based on budget, garden orientation and the look of your Shirley property.
