26/0952/HSE

The proposed development, by reason of the cumulative size, siting, design, bulk and massing of the side and rear extensions, would fail to represent subordinate additions to the host property, appearing as an unduly bulky, overly dominant, prominent and unsympathetic addition that will lead to less than substantial harm to the significance of a designated heritage asset, against which no public benefits such as to outweigh the harm have been identified and which would fail to preserve or enhance the character and appearance of the Watling Estate Conservation Area, contrary to Policies D3 and HC1 of the London Plan (2021), NPPF; Policy CDH01; CDH05 and CDH08 of the LB Barnet Local Plan (2025), the Residential Design Guidance SPD (2016) and the Watling Estate Conservation Area Character Appraisal (2007)
