Why it was refused
- The proposed development would fail to satisfy the criteria contained in Class A.1(j)(i), (ii) and (iii) and (ja), Part 1, Schedule 2 of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended) because; the property has an existing two storey rear extension (approved under application TP/72/2397) which the proposed single storey side extension would attach to. As such, the enlarged part of the dwellinghouse would extend beyond a wall forming a side elevation of the original house, and would exceed 4 metres in height, would have more than a single storey and would have a width greater than half the width of the original dwellinghouse and any total enlargement (being the enlarged part together with any existing enlergement of the original dwellinghouse to which it will be joined) would exceed the limits set out in sub-paragraphs (e) to (j). Accordingly, the application for a Certificate of Lawful Development (Proposed) is refused. First Schedule (description of operations) Construction of single storey side extension. Certificate of Lawful Development (Proposed).
