Covering Stockton-on-Tees
Our survey diary covers Stockton-on-Tees, including TS16, TS17, TS18, TS19, TS20, TS23. Nearby, we also take on projects in Billingham (2 miles), Thornaby-on-Tees (3 miles), Yarm (5 miles), Hartlepool (9 miles).
Middlesbrough, in North Yorkshire, is roughly 3 miles from Stockton-on-Tees and also on our list. Across the North East, houses often have rear yards or modest gardens, so compact, well-lit single-storey extensions make the biggest difference.
Is a wraparound extension right for your house?
- Families who want kitchen, dining and living in one space
- Semi-detached houses with a side passage
- Terraced houses that want the largest ground floor possible
The corner is where wraparounds succeed or fail. We usually use a single steel goalpost or a corner post hidden in a pier, and set the glazing so the new room reads as one space rather than two boxes.
Planning rules that apply in Stockton-on-Tees
In England a wraparound extension is assessed as both a side and a rear extension, and the combination usually falls outside permitted development, so most need a householder planning application (£548 from 1 April 2026).
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).

Questions people ask about wraparound extensions
Do you cover all of Stockton-on-Tees?
Yes. We cover Stockton-on-Tees and the surrounding parts of County Durham. Site visits are free and there is no obligation.
Do I need building regulations approval in Stockton-on-Tees?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Will my neighbours in Stockton-on-Tees be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
Is a wraparound better than a side return alone?
It adds far more space, but costs more and needs planning permission more often. Our comparison guide sets the two side by side.
Will I need to move a drain?
Often. Side returns frequently contain a manhole or a shared drain. Building near or over a public sewer needs the water company’s consent in England and Wales, which we arrange.
