What you can build in Trowbridge depends almost entirely on which half of the town you are in. The estates built from the 1960s onwards — Studley Green, Hilperton Marsh, Paxcroft Mead — generally have the plot width and the permitted development rights to take a proper rear or wraparound extension without a full planning application, which is why space-adding work is worth doing there. The Georgian and Victorian centre around Fore Street and Court Street is largely Conservation Area, so the same extension needs a different approach: planning consent, sympathetic materials, and a realistic conversation about what the council will actually pass before anyone draws anything. We work across both, and we will tell you at the site visit which category your property falls into and what that means for cost and timescale. It is exactly this balance — extensions and renovations on the estate stock, double-storey and over-structure additions, and careful period work in the town centre — that drives most of the building work we carry out in Trowbridge.
