About this application

This is a planning application for a single storey rear extension at 157 Micklefield Road High Wycombe Buckinghamshire HP13 7HA. Buckinghamshire has handled 10,863 applications of this type. This one was decided in 35 days, 3 weeks quicker than Buckinghamshire's typical decision time. There are no previous applications recorded at this address. In the past year there have been 60 applications across Marsh and Micklefield. We hold 2,292 applications in total for the HP13 postcode area.

Why it was refused

  1. Prior approval from the Local Planning Authority is required and refused in this instance. The proposed development fails to comply with all the criteria set out in Class A, Part 1 of Schedule 2 of the Town and Country Planning (General Permitted Development) (England) Order 2015, as amended. The proposed would have an eaves height up to 3.1m high, measured from the highest part of the sloped grounds. As such, the proposal fails to comply with Para A.1(i). The resultant width of the rear extension proposed would have a total combined width which is more than half the width of the original dwellinghouse (Paragraph (j)(iii) ) and the proposed works would involve excavations and the partial removal of the existing retaining wall which is greater than 300mm in height, which would constitute "development" as defined by Section 55(1) of Town and Country Planning Act 1990. Therefore this proposal fails to comply with Paragraph A.1(k)(i) Schedule 2 of the Town and Country Planning (General Permitted Development) (England) Order 2015, as amended. Mindful of the above, the prior approval of the proposed works is refused and express planning permission is therefore required.

From the council's decision notice.
