1. 1.A Certificate of Lawfulness (proposed) cannot be issued for the following reasons: The proposed dormer to the main roof would extend beyond the plane of the existing roofslope, which forms the principal elevation of the dwellinghouse. Therefore, the proposed dormer would fail to comply with B.1(c). Additionally the submitted block plan indicates a single storey rear, side and front extension. The eaves height of the proposed single storey rear extension, shown on the block plan can not be determined, as such the proposal has not demonstrated compliance with criterion A.1 (i). The proposed single storey rear extension would be attached to a side extension and would extend beyond a wall forming a side elevation of the original dwellinghouse, and therefore would have a width greater than half the width of the original dwellinghouse, thereby failing to comply with criterion (ja) because when considered cumulatively the proposal would not comply with criteria (j)(iii). The proposed side extension fails to comply with criterion A.1(e) because the enlarged part would extend beyond a wall forming the principal elevation of the original dwellinghouse and that wall fronts a highway. In addition, insufficient information has been provided regarding the proposed eaves height, and as the enlarged part of the dwellinghouse is located within 2 metres of the boundary, compliance with criterion A.1(i) cannot be demonstrated. The proposal therefore fails under criterion A.1(i). The proposed side extension would also extend beyond a wall forming a side elevation of the original dwellinghouse and would have a width greater than half the width of the original dwellinghouse. Therefore, the proposal fails to comply with criterion A.1(j)(iii). When assessed cumulatively with the other proposed enlargements, the combined works would exceed the limits set out in sub paragraphs (e), (i) and (j). Accordingly, the proposal fails under criterion A.1(ja). The proposed front extension fails to comply with criterion A.1(e) because it would extend beyond a wall forming the principal elevation of the original dwellinghouse, and that wall fronts a highway. Furthermore, as the extension is positioned within 2 metres of the boundary and no eaves height has been provided, compliance with criterion A.1(i) cannot be demonstrated. The proposal therefore fails this requirement. The enlarged part would also extend beyond a wall forming a side elevation of the original dwellinghouse and would have a width greater than half the width of the original dwellinghouse. Therefore, the proposal fails criterion A.1(j)(iii). When assessed cumulatively with the other proposed enlargements, the combined works would exceed the limits set out in sub paragraphs (e), (i) and (j). Accordingly, the proposal fails under criterion A.1(ja). THIS IS AN IMPORTANT DOCUMENT AND IS LIKELY TO BE REQUIRED WHEN YOU COME TO SELL YOUR PROPERTY. YOU ARE ADVISED TO KEEP IT WITH YOUR TITLE DEEDS. Ref No. 5/24/1053 D.C.17 The proposal would therefore be contrary to A.1 (e), (i), j(ja), j(iii) and B.1(c) of Class A and B, Part 1, Schedule 2 of the Town and Country Planning (General Permitted Development) (England) Order 2015 as amended. Formal planning permission would therefore be required.
