Most home extensions in Leyton complete within 12 to 20 weeks from groundworks to handover. Single-storey rear extensions take 12–14 weeks, side returns around 10–12 weeks, and double-storey extensions 16–20 weeks. Timelines depend on planning permission duration, groundworks complexity, and Building Control inspection stages. Where party wall agreements are required — common with Leyton's terraced street patterns — additional lead time should be anticipated.
