S.T Contracts Ltd is based in Watford. We build garden rooms across St Albans, Radlett, Chorleywood, Harpenden and surrounding areas within roughly a 20 mile radius of Watford. For larger projects we'll consider travelling up to 25 miles - get in touch and we'll let you know if we can help.

We build on site, not deliver a pre-built unit. This means we can work with limited access - materials can be carried through side gates or even through the house if needed.
