Scheme description

Single storey rear/side extension with conversion of garage into habitable room involving alterations to front elevation.

Why it was refused
Reason 1

The proposed development, in absence of an adequate flood risk assessment, fails to demonstrate how proposed measures manage the risk of flooding and utilise Sustainable Urban Drainage Systems (SuDS) following the drainage hierarchy in the London Plan. The proposal is therefore contrary to Section 14 of the National Planning Policy Framework (2024), to policies SI12 and SI 13 of the London Plan (2021), to policies CP21 and CP28 of the Enfield Core Strategy (2010), to policies DMD59, DMD60 and DMD61 of the Enfield Development Management Document (2014), and the Enfield Strategic Flood Risk Assessment. Dated: 14 April 2026 Authorised on behalf of: Karen Page Head of Planning and Building Control Housing, Regeneration and Development Department Enfield Council PO Box 53, Civic Centre Silver Street, Enfield EN1 3XE If you have any questions about this decision, please contact the planning officer Jeremiah.ayerh@enfield.gov.uk.
