Semi-detached rear extension in Hadley
Single or two-storey extensions for semi-detached houses, with side access and one party wall. We design, get the approvals for and build rear extensions for semi-detached houses in Hadley and the surrounding area, with one contract from the first survey to building control sign-off.
Hadley and its postcode districts TF1, TF2 and TF5 are part of our Shropshire coverage. Where a Hadley semi already has a small lean-to at the back, we usually replace it rather than extend it.

Do you need planning permission for a semi-detached rear extension in Hadley?
Whether your semi-detached rear extension in Hadley 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.
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.
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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Hadley like to extend?
Red-brick terraces and 1930s semis make up much of Hadley. Many already have a small kitchen lean-to at the back, which a new rear extension usually replaces rather than adds to.
