House Extensions in Trowbridge
Rear, side-return, wraparound and double-storey extensions across Wiltshire's county town — plus renovations and period property care, from the Georgian centre out to the estates.
Extending a Trowbridge Home: What Works Where
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.

Trowbridge FAQs
Do I need planning permission for a house extension in Trowbridge?
It depends which part of town you are in. On the post-1960s estates — Studley Green, Hilperton Marsh, Paxcroft Mead — many single-storey rear extensions fall under permitted development, so no full application is needed. In the Conservation Area covering the Georgian and Victorian centre around Fore Street and Court Street, permitted development rights are restricted and you will almost certainly need consent. We check which applies to your address at the free site visit before you spend anything on drawings.
What is a wraparound extension, and will one work on my Trowbridge house?
A wraparound combines a rear extension with a side-return infill, turning the whole back of the house into one space. It needs enough side width to be worth doing, which is why it suits the wider estate plots in Trowbridge better than the tighter town-centre terraces. We will measure and tell you honestly whether a wraparound or a straight rear extension gives you more usable room for the money.
Can you build a double-storey extension in Trowbridge?
Yes. Double-storey and over-structure extensions — building above an existing single-storey element such as a garage or kitchen — are common on Trowbridge estate housing. Both need building control sign-off and structural calculations for the foundations and any new steel, and a double-storey almost always needs full planning permission rather than permitted development.
How much does a house extension cost in Trowbridge?
It depends on size, ground conditions, access and how much structural work the existing house needs, so we do not quote blind or work to a rate per square metre. Every Trowbridge enquiry gets a free site visit and a fixed-price, fully itemised quote before any work starts — no day rates, no provisional sums that creep.
