155 Main Road Great Leighs Chelmsford Essex CM3 1NP

1. 1.Reason 1 Planning permission was previously granted for the demolition of the existing dwelling and outbuildings, and their replacement with three five-bedroom and four four-bedroom terraced dwellings, under application reference 03-02200-FUL. This permission is the governing planning consent for the construction of this property. Condition 8 of this permission stipulated that: "Notwithstanding the provisions of the Town and Country Planning (General Permitted Development) Order 1995 (or any Order amending, revoking or re-enacting that Order), the dwellings hereby granted permission shall not be enlarged or extended without the grant of an additional planning permission by the local planning authority." 25/01750/CLOPUD This planning permission has been implemented. The proposed single storey extension would be in contravention of Condition 8 and would not therefore constitute Permitted Development. This is in accordance with Sub Paragraph 3. (4) of "Permitted Development" of the General Permitted Development Order (GPDO) which states: Nothing in this Order permits development contrary to any condition imposed by any planning permission granted or deemed to be granted under Part 3 of the Act otherwise than by this Order. The development is not permitted development under of Schedule 2, Part 1, Class A of The Town and Country Planning (General Permitted Development) (England) Order 2015 and planning permission is required. Reason 2 The proposed rear extension physically adjoins the original outbuilding. Once joined, the outbuilding is no longer assessed as a separate structure. Consequently, the combined projection must be measured as a single extension from the rear wall of the original dwellinghouse. The resulting depth is approximately 7.4m. This exceeds the limits set out under Class A, specifically: A.1(f) and A.1(g). Therefore, the development cannot be considered permitted development under of Schedule 2, Part 1, Class A of The Town and Country Planning (General Permitted Development) (England) Order 2015 and planning permission is required. Reason 3 Insufficient evidence has been provided in order to assess the following condition of Schedule 2, Part 1, Class A of The Town and Country Planning (General Permitted Development) (England) Order 2015. Condition A.3(a): "The materials used in any exterior work (other than materials used in the construction of a conservatory) must be of a similar appearance to those used in the construction of the exterior of the existing dwellinghouse". Therefore, planning permission is required.
