Planning and approvals in Bedfordshire
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.
In a conservation area, national park, National Landscape, the Broads or a World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.
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).
What should I budget for a porch extension in Bedfordshire?

Working in Bedfordshire
Towns we cover in Bedfordshire include Luton, Bedford, Dunstable, Leighton Buzzard, Ampthill, Kempston. Across the East of England many houses sit on generous plots, and single-storey and wraparound extensions are a natural fit.
Included in a typical project
- Brick, render or oak frame walls
- Design to suit the house style
- Tiled, slate or flat roof
- Planning check against the porch limits
- Foundations and drainage for rainwater
Proportion matters on a porch more than on any other extension, because it is at the front. We match the roof pitch and brick and keep the front door in proportion with the house windows.
