Planning rules that apply in Middlesbrough
In England a single-storey extension to a bungalow follows the normal permitted development limits (3 m or 4 m, or 6 m and 8 m through prior approval). Adding a first floor always needs planning permission.
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.
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.
Applications are decided by the local planning authority (your district, borough or unitary council).
Covering Middlesbrough
We cover Middlesbrough and the postcode districts TS1, TS2, TS3, TS4, TS5, TS6. We also work in nearby Redcar (8 miles), Northallerton (19 miles), Whitby (22 miles), Ripon (32 miles).
Billingham, in County Durham, is roughly 2 miles from Middlesbrough and also on our list. Homes across Yorkshire and the Humber range from back-to-back and through terraces to large suburban semis, and extension options vary with them.
When a bungalow extension makes sense
- Homeowners planning for later life
- Families wanting more space on one floor
- Bungalows on larger plots
Bungalow roofs are often hipped, which makes tying in an extension roof a careful job. We draw the roof junction early because it drives both the look and the cost.

Common questions in Middlesbrough
Do I need building regulations approval in Middlesbrough?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Will my neighbours in Middlesbrough be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Middlesbrough, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Can I extend a bungalow without planning permission?
In England a single-storey rear extension to a bungalow follows the same permitted development limits as a house: 3 m or 4 m, or up to 6 m or 8 m through prior approval. Adding a storey always needs planning permission.
How much does a bungalow extension cost?
Our guide range for single-storey work is about £1,640 to £3,200 per m² including VAT. Going upwards is priced after a structural survey.
