Bungalow rear extension in Hetton-le-Hole
Single-storey rear extensions that keep everything on one level. We design, get the approvals for and build rear extensions for bungalows in Hetton-le-Hole and the surrounding area, with one contract from the first survey to building control sign-off.
Hetton-le-Hole is covered from our County Durham round, including DH4 and DH5. For Hetton-le-Hole 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 Hetton-le-Hole?
Whether your bungalow rear extension in Hetton-le-Hole 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.
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. 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 Hetton-le-Hole like to extend?
Terraces and semis are typical around Hetton-le-Hole. 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 Hetton-le-Hole
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
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.
Can I extend the loft as well?
Sometimes, but that is a different project; a rear extension keeps everything on one level.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Can you match the brick or stone on my Hetton-le-Hole house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
