6 First Avenue Acton W3 7JR

1. 1.The proposed development, by reason of the enlarged roof form, increased bulk and massing, provision of an internal staircase, and substantial upper-level accommodation, would result in an outbuilding that appears more akin to a two- storey structure than a subordinate ancillary garden building. The proposal would fail to respect the character of the approved outbuilding or the established pattern of development along the rear accessway and would appear as an overly dominant and visually intrusive feature within the rear garden environment. The development would therefore be harmful to the character and appearance of the site and surrounding area, contrary to Policies D3 and D4 of the London Plan (2021) and Policies 7.4 and 7B of the Ealing Development Management Development Plan Document (2013).
2. 2.The proposed development, by reason of the introduction of an accessible upper level roof space and associated window opening, would result in increased opportunities for overlooking of neighbouring properties and gardens, giving rise to an unacceptable loss of privacy. Furthermore, the increased bulk and scale of the outbuilding would create an undue sense of enclosure and adversely affect the outlook enjoyed by neighbouring occupiers. As such, the proposal would result in unacceptable harm to the living conditions of adjoining residents, contrary to Policy D3 of the London Plan (2021) and Policies 7.4 and 7B of the Ealing Development Management Development Plan Document (2013).
3. 3.The proposed internal layout, including the provision of a permanent staircase and substantial upper level floor space, would create a building with the characteristics of a two-storey structure and would fail to demonstrate that the roof space would remain genuinely incidental and subordinate to the use of the host dwellinghouse. Consequently, the proposal would represent an inappropriate form of ancillary accommodation that would be contrary to the objectives of Policies D3 and D4 of the London Plan (2021) and Policies 7.4 and 7B of the Ealing Development Management Development Plan Document (2013).
