Local to Darlington
Site visits are available across Darlington (DL1, DL2, DL3). We also work in nearby Newton Aycliffe (7 miles), Yarm (8 miles), Stockton-on-Tees (10 miles), Thornaby-on-Tees (10 miles).
For homes towards North Yorkshire, Middlesbrough is around 13 miles away. The North East has many brick terraces, colliery-era housing and post-war semis, with rear extensions and kitchen extensions the most common requests.
When a porch extension makes sense
- Homes wanting better kerb appeal
- Busy hallways with no storage
- Front doors that open straight into a living room
Planning and approvals in Darlington
In England a porch is usually permitted development if its ground floor area is no more than 3 m² measured externally, no part is over 3 m high, and no part is within 2 m of a boundary next to a road.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
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.
Applications are decided by the local planning authority (your district, borough or unitary council).

It starts with a visit to your house to measure, check access and talk through ideas and budget.
Design and approvals
Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.
Fixed written price
We confirm the build price in writing, based on the approved drawings and the finishes you have chosen.
Build and sign-off
Work is carried out to the agreed programme, inspected by building control and signed off at the end.
Porch extension questions answered

On site, typically 2 to 4 weeks once approvals are in place. Before that, allow 2–8 weeks design and approvals.

Yes. The guide prices on this page are adjusted for Darlington, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.

Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
