How long will House Extension take?
A single-storey extension typically takes 8–16 weeks from groundworks to completion. Larger projects like a full house renovation or loft conversion can take 3–6 months. Your builder should provide a project schedule before work starts.
What qualifications should my builder have?
Look for builders who are members of the Federation of Master Builders (FMB) or TrustMark registered. These schemes require members to meet quality standards, hold insurance, and adhere to a code of conduct.
