Local to Burnley
We cover Burnley and the postcode districts BB8, BB9, BB10, BB11, BB12. Neighbouring towns we cover include Nelson (3 miles), Colne (5 miles), Accrington (6 miles), Rawtenstall (7 miles).
Rochdale, in Greater Manchester, is roughly 13 miles from Burnley and also on our list. Across the North West, terraced houses with small rear yards suit compact rear and side return extensions, while suburban semis have room for more.
What we take care of
- Planning drawings: existing and proposed plans and elevations, site and location plans
- Building regulations drawings and specification
- Structural calculations from an engineer (full pack)
- 3D views to check the look and the light (full pack)
- Measured survey of the house and garden
The most expensive changes are the ones made after the steel is ordered. A good design stage settles layout, heights, glazing and services on paper, so the build price is firm.
Will the council need to approve it?
In England the main routes are permitted development (ideally confirmed with a lawful development certificate, £274), larger home extension prior approval (£249, 42 days) and a householder planning application (£548, normally 8 weeks), with council fees as set 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.
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).
