Why it was refused

  1. The proposed development does not constitute permitted development under Schedule 2, Part 1, Class A of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended). The application has been submitted under the prior approval procedure for larger home extensions; however, the submitted plans indicate the demolition of an existing extension as part of the proposed works. The prior approval procedure under Class A only permits the enlargement, improvement or alteration of a dwellinghouse and does not allow for the demolition which is defined as development under section 55 of the Town and Country Planning Act 1990. As such, the proposal falls outside the scope of the permitted development rights for larger home extensions and cannot be considered under the prior approval process. Full planning permission is therefore required.

From the council's decision notice.
