18 Haling Park Road: six homes supported by detailed site evidence
23/00233/FUL · APP/L5240/W/23/3321227 · Appeal allowed with conditions, 24 November 2023
The inspector granted permission to replace a house and garage with six family houses. The stepped layout responded to the slope and surrounding buildings. Updated tree evidence, drainage information, access drawings and a unilateral undertaking addressed issues raised by the council.
What to check: For a redevelopment, test levels, neighbours, trees and access together. The grant included conditions securing further details; it was not an unconditional approval or a householder PD decision.

Questions about planning in Croydon
Do I need planning permission for my project in Croydon?
Some house extensions, loft conversions and outbuildings can use permitted development rights in Croydon, but size alone does not establish eligibility. Check the property type, previous extensions, planning conditions and the rules for the proposed work. Householder rights do not apply to flats. Conservation areas and Article 4 directions restrict particular rights; they do not automatically require an application for every change. Listed building consent is a separate requirement for works affecting a listed building's special interest.
