How much does a garden room cost in Merton?
A typical Merton garden room works out at about £10,000–£38,500 in 2025. 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. Expect size and insulation spec and power, glazing and internal fit-out to move the price most, along with foundations and groundwork. 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.
