SW16 straddles the Croydon, Lambeth and Merton boundaries, so the authority check comes first.
Local contextNorbury straddles the SW16 and CR7 postcodes, primarily within the London Borough of Croydon. The neighbourhood's mix of Victorian terraces, Edwardian houses, and inter-war properties offers excellent potential for extensions and loft conversions at some of south London's most accessible prices.
Victorian and Edwardian terraces: Norbury's period terraces are well suited to rear dormers, single-storey rear extensions, and side-return infills. Under permitted development, many of these works can proceed without planning permission. We confirm PD eligibility and prepare building regulations drawings.
Affordable improvement: Norbury's relative affordability makes it a popular area for families buying properties to extend and improve. We help homeowners identify the most impactful alterations and navigate the planning and building regulations process efficiently.
Croydon design guidance: Croydon Council's Place-Specific Guidance provides area-by-area design expectations. We design schemes that comply with this guidance, improving policy alignment before submission.
Permitted development: Most Norbury properties benefit from full PD rights. Loft conversions, rear extensions, and outbuildings can typically proceed without planning permission. We confirm eligibility and prepare compliant building regulations drawings.
