Section 01
Development description
described as “proposed single storey 5m rear extension”.
Section 02
Decision
The appeal is dismissed.
Section 03
Main Issue
The main issue is whether the proposed development would comply with the conditions, limitations or restrictions applicable to development permitted, having regard to Class A of Schedule 2, Part 1 of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended) (the GPDO).
Section 04
Reasons
Schedule 2, Part 1, Class A of the GPDO states that the enlargement, improvement or other alteration of a dwellinghouse is permitted development. [name].1 sets out the relevant exceptions and limitations of the permitted development rights.
[name].1 (j) states that development is not permitted by Class A if the enlarged part of the dwellinghouse would extend beyond a wall forming a side elevation of the original dwellinghouse, and would exceed 4 metres in height, have more than a single storey, or have a width greater than half the width of the original dwellinghouse. It is this last point regarding the width which is the matter in dispute.
The proposal would extend beyond a wall forming the side elevation. This side elevation being the kitchen wall which has a window facing the side boundary of the site. The infill section of the proposal which would be formed between the existing kitchen side elevation and the boundary of the site would be less than half the width of the original dwellinghouse.
The width of the rearmost part of the extension, which would extend beyond the kitchen wall side elevation, would be equal to the width of the original dwellinghouse. Therefore, this part of the extension would have a width greater than half the width of the original dwellinghouse and would fail to meet the criteria in paragraph A.1(j) of the GPDO. The proposed extension can therefore not be classed as permitted development.
The appellant has indicated that the proposal would not extend more than 6 metres from the rear of the original dwellinghouse and would be in accordance with paragraph A.1(g) of the permitted development rights for householders technical guidance. This matter does not alter my findings above with regards to paragraph A.1(j).
My attention has been drawn to a number of other schemes1 which have been granted by the Council or by planning appeal. However, insufficient evidence has been provided and I cannot be sure that they represent a direct parallel with the appeal scheme particularly with regards to scale and dimensions. In any case, I have determined this appeal on its own merits.
Section 05
Conclusion
For the reasons given above, I conclude that the appeal should be dismissed.
