Covering Darlington
Alongside Darlington, we also cover Newton Aycliffe (7 miles to the north), Stockton-on-Tees and Thornaby-on-Tees.
Homes in the North East
Housing across the North East ranges from colliery terraces and Tyneside flats to suburban semis and modern estates, each with different options for extending.
What goes into an upward extension?
The first question is whether the existing walls and foundations can carry the extra load, so we start with a structural survey. Then we design either a full first floor or a raised roof with dormers, handle planning or prior approval, and build the new storey while protecting the floor below.
- Roof removal and temporary weather protection
- New first-floor structure, walls and roof
- Staircase and changes to the ground floor layout
How much should I budget for an upward extension?

How is an upward extension approved in Darlington?
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, Class AA permitted development allows an extra storey on many detached and semi-detached houses built between July 1948 and October 2018, subject to a prior approval application covering design, neighbours’ amenity and other matters.
What should I think about before starting?
- The house is exposed while the roof is off, so the sequence is planned tightly.
- Neighbours’ light and privacy are the main planning tests.
From first call to completion
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
