How much does a garden room cost in Harrow?
In Harrow, 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. What you pay depends mainly on size and insulation spec and foundations and groundwork, plus 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?
In Harrow, expect a typical garden room to take about 2–5 weeks once work begins.
- Insulate properly. Good insulation is what makes a garden room usable all year.
- 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.
