Why it was refused

The two storey side extension and the roof extensions, by reason of their size, siting, form and design would result in a visually dominant and incongruous addition that would fail to respect the form, proportions and appearance of the existing dwelling and surrounding area. The proposal would be contrary to Policies D3 and D4 of the London Plan 2021 and Policies SP4 and DM10 of the Croydon Local Plan 2018.

From the council's decision notice.
