Do you need planning permission for a glazed rear extension in Chaddesden?

Planning for a glazed rear extension in Chaddesden follows the English householder rules.

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.

New fabric must meet Approved Document L (2021 edition incorporating 2023 amendments): walls 0.18, roof 0.15 and floor 0.18 W/m²K, windows 1.4 W/m²K or Band B. Under the simple route, new windows, doors and rooflights should not exceed 25% of the extension floor area plus any openings removed; more glass is possible with a whole-house calculation.

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 Chaddesden like to extend?

Red-brick terraces and semis are typical of Chaddesden. Coal-mining legacy areas in parts of the East Midlands can need a Coal Authority check before foundations are designed.

FAQ

Glazed rear extension questions in Chaddesden

Do I need planning permission for a rear extension in Chaddesden?

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.

Can you match the brick or stone on my Chaddesden house?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

Sliding or bifold doors?

Sliders give bigger panes and slimmer sightlines; bifolds open the whole width. Our guide compares them.

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
