A garden annexe is a practical way to add a private, self-contained space without moving home. In SE10, we build annexes that work as guest suites, home offices, or independent living for family. We regularly work near Greenwich Park and around Maze Hill, designing layouts that suit compact gardens as well as deeper plots. Every build is tailored, from foundations to final finishes.
Greenwich homes range from Georgian townhouses to Victorian villas and modern waterfront apartments, each with different access and garden shapes. We design annexes that respect period proportions while delivering contemporary performance and comfort. Whether you’re in Blackheath with mature trees or in Deptford with tighter boundaries, we plan the footprint and orientation carefully. The result is a space that feels like part of the property, not an afterthought.
We start with a site visit, measured survey and clear specification, then provide a fixed-scope programme before work begins. Your annexe is built with proper insulation, certified electrics, and compliant plumbing, with planning support where needed. We keep neighbours in mind, manage deliveries, and maintain a tidy site throughout. Homeowners choose us for reliable communication, high-end finishes, and workmanship backed by warranty.
In the garden annexes Greenwich area, access can be tight on residential streets, so we plan deliveries and waste removal to minimise disruption. Many plots have mature landscaping and tree constraints, especially near Greenwich Park and Blackheath, which can influence foundations and layout. We also factor in parking controls and neighbour proximity common to SE10. Where approvals are needed, we align designs with Royal Borough of Greenwich expectations and provide the right supporting information.

Costs in Greenwich typically range from £45,000–£90,000+ depending on size, specification and whether you include a full bathroom and kitchenette. A compact, well-insulated studio-style annexe usually sits at the lower end, while larger, higher-finish builds with premium glazing, underfloor heating, and bespoke joinery move higher. Groundworks, access constraints in SE10, and utility connections can also affect the final budget.
Most garden annexes take around 6–12 weeks from start on site to completion, depending on complexity and finishes. Simpler builds with straightforward access and fewer service runs can be quicker, while larger annexes with bathroom plumbing, kitchenette fit-out, and bespoke glazing take longer. Lead times for materials, ground conditions, and any required inspections can also influence the programme. We provide a clear schedule before work begins.
Many garden buildings can fall under permitted development, but a self-contained annexe may trigger extra considerations, especially if it’s intended for independent living. In the Royal Borough of Greenwich, rules around height, proximity to boundaries, and how the space is used can affect whether permission is required. We review your site, advise on the likely route, and provide planning support, drawings and documentation to help you proceed compliantly.
We provide a 10-year warranty covering workmanship and key build elements, giving you confidence long after completion. This includes the structural build quality and installation standards for the main fabric of the annexe. Manufacturer warranties apply separately to items such as windows, doors, and certain electrical components. We also hand over clear care guidance and remain available for aftercare queries should anything need attention.
We offer a wide range of options, from contemporary composite cladding and aluminium glazing to timber finishes that suit period homes. Popular choices include warm roof systems, large sliding or bifold doors, acoustic insulation, and integrated storage. Internally, we can fit compact kitchenette layouts, shower rooms, and bedroom zoning to maximise space. We guide you through finishes and performance upgrades to match your budget and how you’ll use the annexe.
