How much does a garden room cost in London?
Expect a garden room in London to cost roughly £10,000–£38,500, based on typical local projects. 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. Price comes down to size and insulation spec, foundations and groundwork and power, glazing and internal fit-out more than anything else. 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?
Typical London garden rooms & outbuildings timescales run to about 2–5 weeks on site.
- Check permitted development. Most garden rooms don’t need planning — confirm size and height limits.
- Plan the services. Running power (and sometimes water) needs designing in from the start.
- Get the base right. A level, well-drained base is essential for a lasting build.

Why a garden room makes sense in London
Demand for quality home improvement in Greater London keeps growing, and a garden room in London can transform how you use your space. A garden room adds insulated, flexible space — office, gym or studio — without the disruption of extending.
Planning your garden room in London
In Greater London, tight sites, party-wall agreements with neighbours and borough-specific planning rules make an experienced local specialist especially valuable. Factor that in early, budget a sensible contingency, and get everything in writing before work starts.
Local know-how for London
The housing across Greater London spans Victorian and Georgian terraces, flat conversions and new-build apartments on tight urban plots. That mix shapes how a garden room is approached here — party-wall agreements, borough-specific planning and widespread conservation areas all apply. A local specialist who knows London will factor all of this into your quote and design.
