Why it was refused
- The proposed single-storey rear extension, by reason of its excessive cumulative depth of approximately 6.8 metres when combined with the existing rear extension, would result in a dominant and disproportionate form of development that would fail to remain subordinate to the host dwelling. The proposal would appear unduly bulky and out of keeping with the character and appearance of the host property and surrounding area, causing harm to the established pattern of development within the locality. As such, the proposal would be contrary to Policies D3 and D4 of the London Plan (2021) and Policy 7.4 of the Ealing Development Management DPD (2013) and the guidance contained within the Ealing Housing Design Guidance.
- The proposed single-storey rear extension, by reason of its depth, projection and siting adjacent to the shared boundary with No. 154 Dormers Wells Lane, would breach the 45-degree guideline and result in an unacceptable loss of light and outlook, as well as an increased sense of enclosure to the occupiers of that neighbouring property. The proposal would therefore have an unacceptable adverse impact on the living conditions of neighbouring occupiers, contrary to Policy 7B of the Ealing Development Management DPD (2013).
From the council's decision notice.
