Covering Washington
Washington is about 6 miles south-east of Newcastle upon Tyne. We also cover Chester-le-Street (4 miles to the south-west), Felling and Houghton-le-Spring.
Homes in the North East
The North East has terraced housing including Tyneside flats, inter-war semis and post-war estates, so loft conversions, rear extensions and layout changes are popular ways to add space.
What does a wraparound extension involve?
A wraparound extension combines a side return and a rear extension into one L-shaped build, giving the biggest possible ground-floor space on terraced and semi-detached houses. It usually creates a large open-plan kitchen, dining and living area across the back of the house.
- Party wall process with both neighbours if needed
- Pitched, flat or glazed roof with rooflights
- Optional kitchen supply and installation

How is a wraparound extension approved in Washington?
Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.
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. Most need householder planning permission, which usually takes around eight weeks once validated.
What can affect a wraparound extension?
- Roof water from an L-shape needs careful falls and outlets.
- An open-plan space this size needs a heating plan, often underfloor heating.
