How much does a garden room cost in Southampton?
A typical Southampton garden room works out at about £9,000–£34,500 in 2025. South East costs typically run above the UK average — Hampshire 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?
Most garden rooms & outbuildings projects in Southampton take around 2–5 weeks, depending on scope and specification.
- 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.
