Do you need planning permission for a single-storey rear extension in Failsworth?
Whether your single-storey rear extension in Failsworth 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 Failsworth like to extend?
Failsworth has long runs of terraced houses with back yards and alleys, plus 1930s semis further out. Yard extensions on terraces are often single-storey and close to both boundaries.

FAQ
Single-storey rear extension questions in Failsworth
What postcode areas do you cover around Failsworth?
Including M35, OL8 and OL9, and the surrounding Greater Manchester area.
Can you match the brick or stone on my Failsworth house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Will the extension make the room behind it dark?
Not if it is designed well. Rooflights or a lantern over the old back room, and a wide opening into it, keep daylight reaching the middle of the house.
Is the site visit in Failsworth free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
How long does a rear extension take to build in Failsworth?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
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.
