Planning Decision
Why it was refused
- The proposed roof extension by reason of its excessive height and bulk, design and siting in this plot would result in a dominant, excessive, visually intrusive, overbearing and incongruous form of overdevelopment that would harm the architectural composition of the plot/site, character and appearance and visual amenities of the East Avenue and Glebe Road streetscene. The proposal would therefore be contrary to Policy BE1 of the Hillingdon Local Plan: Part One - Strategic Policies (2012), Policies DMHB 11, DMHB 12 and DMHD 1 of the Hillingdon Local Plan: Part Two- Development Management Policies (2020) Policies D3 and D4 of the London Plan (2021), and the National Planning Policy Framework (2026).
- The proposed roof extension, by virtue of its excessive height, scale, bulk and siting in close proximity to the site boundaries would be detrimental to the occupiers of the surrounding context in terms of sense of enclosure, visual impact, overbearing impact and outlook in relation to the adjoining residential dwellings. Therefore, the proposal would fail to comply with Policy D3 of the London Plan (2021), Policy BE1 and of the Hillingdon Local Plan: Part One - Strategic Policies (2012) and Policies DMBH 11 and DMHD1 of the Hillingdon Local Plan: Part Two - Development Management Policies (2020).
