How much does a garden room cost in Lewisham?
As a 2025 guide, most homeowners in Lewisham pay somewhere between £10,000–£38,500 for a garden room. 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.
