Rear extensions for detached houses in Leicestershire and Rutland
Wider, deeper rear extensions with room for vaulted roofs and big glazing. We design and build rear extensions across Leicestershire and Rutland, from Leicester and Loughborough to Hinckley, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Detached houses in Leicestershire and Rutland often have room for a deeper rear extension under England's prior approval route or a full-width design. Red-brick terraces and semis are typical of Leicestershire and Rutland. Coal-mining legacy areas in parts of the East Midlands can need a Coal Authority check before foundations are designed.

Do you need planning permission in Leicestershire and Rutland?
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.
A two-storey rear extension can be permitted development in England only if it projects no more than 3 metres, stays at least 7 metres from the rear boundary, matches the existing roof pitch and has obscure-glazed upper side windows. In practice most double-storey rear extensions go through a householder planning application.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.
