Why it was refused

  1. The Council is not satisfied on the evidence adduced to it that the development specified in the First Schedule hereto and taking place to the building on the land specified in the Second Schedule hereto would be permitted development by virtue of Class F of Part 1 and Class B of Part 2 of Part 1 of Schedule 2 of the Town and Country Planning (General Permitted Development) (England) Order 2015, as amended ("GPDO"). Condition 16 of planning permission W/88/5327 dated 30th March 1988 removed the property's permitted development rights for development under Part 1 and Part 2. It is set out in Condition 16 of planning permission W/88/5327 that: "Notwithstanding the provisions of the Town and Country Planning General Permitted Development Order, 1977 (or any order revoking and re-enacting that Order),no development falling within class(es) I & II (1 &2) shall be carried out without the written permission of the Local Planning Authority. Reason: In order that the Local Planning Authority can properly consider the effect of any future proposals on the character and amenity of the locality" Therefore, the proposed development will require express planning permission. See the attached Appeal Notes for details of appealing this decision.
