What is a double-storey extension?
A double-storey extension (also called a two-storey extension) adds rooms on both the ground and first floor in one build. It typically gives a larger kitchen or living space downstairs and an extra bedroom or bathroom above.
How much does a double-storey extension cost in Ledbury?
In Ledbury, a double-storey extension typically costs £1,600–£2,400 per m² of floor area (both floors), including VAT at 20% (standard rate). For a typical 36 m² project that is roughly £57,500–£86,500. Prices in the West Midlands sit near the national average for this kind of work, and the range for Ledbury reflects that. Design, structural calculations and council fees are extra.

Do you need planning permission for a double-storey extension in Ledbury?
Here is how the rules work for a double-storey extension in England. In England an extension of more than one storey can only be permitted development at the rear, no more than 3 metres deep and at least 7 metres from the rear boundary, with matching materials and any upper side windows obscure-glazed. Most double-storey extensions therefore go through a householder planning application.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
What we handle
From survey to sign-off, the job normally involves:
- Opening up at both levels with steel beams
- Building control sign-off
- Brick or block walls, floors and a roof tied into the house
- Electrics, heating, plumbing and plastering
- Design drawings and planning application
- Structural engineer’s calculations
How long does it take?
Allow 14 to 20 weeks on site, after planning and building control approval. Before that, surveys, drawings and approvals usually take 3 to 4 months, longer if the council asks for changes.

Planning drawings for the application, then more detailed building regulations drawings and structural calculations for building control. We prepare both.
