Section 01
Development description
6m single storey rear extension incorporating new patio doors, window and roof lights.
Section 02
Decision
The appeal is dismissed.
Section 03
Procedural Matters
At the time of my site visit, I observed that a single storey rear extension has been constructed up to eaves height. Both main parties have been invited to comment on this matter. The appellant has subsequently confirmed that works have commenced on a separate proposal submitted & approved via a different application. I have determined the appeal on this basis.
Section 04
[name]
The main issue is whether the proposal is permitted development under the terms of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended) (GPDO).
Section 05
Reasons
The layout of the extension constructed on site varies to that shown on the submitted plans, though the appellant maintains that they still have flexibility to implement features of the proposal. However, prior approval cannot be granted for development that has already begun, whether or not it is wholly or partially completed. The proposal is thus not permitted under Schedule 2, Part 1, Class A of the GPDO. I thus have no need to consider the amenity of adjoining premises.
Section 06
Conclusion
For the reasons given above, I conclude that the appeal is dismissed.
