The government has announced plans to allow homeowners to build a double storey extension under permitted development rights. But, is this a good proposal?

The government announced during this autumn’s Party Conference that homeowners will soon be able to add a double storey extension to their homes without planning permission.

Currently, single storey extensions do not require planning permission but fall under permitted development rights, while double storey extensions still require planning permission. But, under the new plans, double storey rear extensions could be allowed under permitted development rights which will make the process a lot easier and more straight forward.

According to the 2019 HomeOwners Survey carried out by HomeOwners Alliance, one of the biggest barriers to understanding home improvement projects relates to planning permission, affecting 27% of homeowners – or 4.7 million people.
