Why it was refused

  1. The proposed rear/side infill extension, by virtue of its height, depth and proximity to the boundary, would cause a significant and unacceptable loss of outlook, daylight and sunlight to No. 260 Whitehorse Lane's windows and garden. The proposal is therefore contrary to Policies D3 and D6 of the London Plan 2021 and Policies SP4 and DM10 of the Croydon Local Plan 2018.

From the council's decision notice.
