How much does a garden room cost in Hillingdon?

A garden room in Hillingdon usually falls in the £10,000–£38,500 range, though every project is different. 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.

  • Check permitted development. Most garden rooms don’t need planning — confirm size and height limits.
