Do you need planning permission for a kitchen-diner rear extension in Norris Green?
Whether your kitchen-diner rear extension in Norris Green needs a planning application depends on its size, your house and any local restrictions.
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.
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 Norris Green like to extend?
Stone and brick terraces are common around Norris Green. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier. For Norris Green kitchens we plan the extraction route and the island drainage before the slab is poured, so nothing has to be chased in later.

FAQ
Kitchen-diner rear extension questions in Norris Green
Do I need planning permission for a rear extension in Norris Green?
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.
Can I have underfloor heating?
Yes. Wet underfloor heating in the new screed is the usual choice, often with the old room's radiators kept or replaced.
Do you handle building control in Norris Green?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Is the site visit in Norris Green 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 Norris Green house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
