Bungalow rear extension in Sunderland
Single-storey rear extensions that keep everything on one level. We design, get the approvals for and build rear extensions for bungalows in Sunderland and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Sunderland (SR2, SR3, SR4 and SR5) as part of our Tyne and Wear work. For Sunderland bungalows we design the roof first, because the low eaves decide the height of the new room.

Do you need planning permission for a bungalow rear extension in Sunderland?
Here is how the rules in England apply to a bungalow rear extension in Sunderland.
In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part is within 2 metres of a boundary.
If 3 or 4 metres is not enough, England's prior approval route allows 6 metres on a terraced or semi-detached house and 8 metres on a detached house for a single-storey rear extension. Neighbours are consulted, the council decides within 42 days, and the fee is £249, rising to £310 from 8 December 2026.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Sunderland like to extend?
Terraces and semis are typical around Sunderland. 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 Sunderland
Is the site visit in Sunderland free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Can you match the brick or stone on my Sunderland house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Can I extend the loft as well?
Sometimes, but that is a different project; a rear extension keeps everything on one level.
Do I need planning permission for a rear extension in Sunderland?
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.
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.
How long does a rear extension take to build in Sunderland?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
