Do you need planning permission for a bungalow rear extension in Middlesbrough?
Whether your bungalow rear extension in Middlesbrough needs a planning application depends on its size, your house and any local restrictions.
English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres within 2 metres of a boundary.
England also has the larger home extension route: a single-storey rear extension of up to 6 metres on an attached house or 8 metres on a detached house, after prior approval from the council. The council notifies your neighbours and has 42 days to decide; the fee is £249 (£310 for applications made from 8 December 2026). The route is not available on designated land such as conservation areas.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Middlesbrough like to extend?
Terraces and semis are typical around Middlesbrough. On terraces a single-storey rear extension across the back yard is usually the practical choice; semis often have room for more.

FAQ
Bungalow rear extension questions in Middlesbrough
Is the site visit in Middlesbrough free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Do I need planning permission for a rear extension in Middlesbrough?
Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.

Not if the pitch and tiles match. Where the eaves are low, a flat-roofed section with a lantern is an alternative.
What postcode areas do you cover around Middlesbrough?
Including TS1, TS2, TS3, TS4 and TS5, and the surrounding North Yorkshire area.
How long does a rear extension take to build in Middlesbrough?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
