Covering Trowbridge
Trowbridge sits 25 miles south-west of Swindon, with Bath 8 miles to the north-west and Frome 8 miles to the south-west.
Homes in the South West
Homes in the South West range from coastal and rural properties in stone and slate to city terraces and modern estates, so extensions are designed to match the local materials.
What is included in a wraparound extension in Trowbridge?
Because it removes two external walls, a wraparound needs careful structural design and a good plan for the corner where the steels meet. We design, apply for any permissions, build and finish the shell, and can fit the kitchen as part of the same contract.
- Party wall process with both neighbours if needed
- Steel frame or goalpost for the corner opening
- Optional kitchen supply and installation
What will a wraparound extension cost?
Indicative costs for wraparound extensions. London and the South East usually sit towards the top of each range.

How is a wraparound extension approved in Trowbridge?
English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.
In England a wraparound extension is treated as one extension, and because it covers both the side and the rear it does not normally fit within permitted development.
What can change the price or programme?
- The corner steel connection is the critical detail and is designed by a structural engineer.
- Roof water from an L-shape needs careful falls and outlets.
How does the project run?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
Wraparound extensions: common questions
Does a wraparound need planning permission?
Usually yes. In England it combines a side and rear extension, which takes it outside permitted development in most cases.
Can we keep part of the kitchen working?
Often, by sequencing the work so the old back wall comes out last. We agree a plan with you before starting.
