Why it was refused

  1. The Local Planning Authority is not satisfied that the principal elevation of the dwelling has been correctly identified within the submitted plans. The LPA consider the principle elebvation to be the southern elevation. Accordingly, the proposed extension would project forward of the principal elevation and would constitute a front extension rather than a rear extension. The proposal therefore fails to comply with the requirements of Class A.1.e of Part 1, Schedule 2 of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended). Prior approval is therefore refused.

From the council's decision notice.
