How much does a garden room cost in Greenwich?
In Greenwich, a garden room typically costs between £10,000–£38,500, depending on the project. London is the most expensive part of the UK for building work, well above the national average — Greater London labour and materials are a real factor. The biggest cost drivers are size and insulation spec, foundations and groundwork, and power, glazing and internal fit-out. Getting two or three quotes is the best way to see a fair local price, which is exactly what our free matching service arranges.
Figures are a 2025 guide only — your matched installer will give you an accurate, no-obligation quote.
How long does it take?
Once started, expect around 2–5 weeks for a Greenwich garden room.
- Insulate properly. Good insulation is what makes a garden room usable all year.
- Plan the services. Running power (and sometimes water) needs designing in from the start.
- Think about use. An office needs different heating and glazing to a gym or bar.

Garden Rooms & Outbuildings in Greenwich: the 2025 guide
Why a garden room makes sense in Greenwich
A garden room lets Greenwich families stay in the area they love while gaining the space they need. A garden room adds insulated, flexible space — office, gym or studio — without the disruption of extending.
Planning your garden room in Greenwich
Before you start, plan properly: set a realistic budget with a 10–15% contingency, confirm exactly what’s included in each quote, and check whether any permissions or building-regulations approvals apply. A good Greenwich specialist will guide you through this.
Local know-how for Greenwich
Homes in and around Greenwich include Victorian and Georgian terraces, flat conversions and new-build apartments on tight urban plots. Those property types influence the best way to plan a garden room — party-wall agreements, borough-specific planning and widespread conservation areas all apply. A local specialist who knows Greenwich will factor all of this into your quote and design.
