The time-limited permitted development right for larger single storey rear extensions to dwelling houses was introduced in 2013 and extended in 2015 to May 2019. The consultation sought views on making the right permanent enabling dwelling houses to continue to be improved and enlarged.
In May 2019 the government published its response to the larger rear extensions public consultation that ran from 29/10/2018 until 14/01/2019.
The response document states the following:
“We intend to make permanent the time-limited permitted development right for larger single storey rear extensions to dwelling houses, retaining the neighbour consultation. We also intend to introduce an appropriate fee for the prior approval application for this right.”.
