Why it was refused

Reason
As stated on the decision notice
1
The two-storey rear extension by reason of its size, sitting and design, would appear out of place and too prominent, which would fail to preserve or enhance the character or appearance of the conservation area, and as a result, does not comply with Policies DMP1 and BHC1 or the Brent Local Plan 2019-2041.
2
The retained front rooflights, by reason of their sitting, design and appearance, appear overly prominent and highly visible from the street scene and from the properties opposite, detracting from and causing harm to, the character of the Conservation Area. The application therefore fails to comply with policies DMP1 and BHC1 of the Brent Local Plan 2019-2041.
