Why it was refused
Reason
As stated on the decision notice
1
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)
