Planning permission drawings, heritage-sensitive extensions, and loft conversions for Blackheath's Georgian and Victorian properties. MCIAT chartered, fixed fees, conservation area expertise built in.
Blackheath sits in the SE3 postcode, straddling the boundary between the London boroughs of Lewisham and Greenwich. The neighbourhood's elegant Georgian and Victorian architecture, centred on the village and heath, creates one of south-east London's most historically significant residential areas — and one of its most demanding planning environments.
Blackheath Conservation Area: The Blackheath Conservation Area is one of the largest in south-east London, covering the village centre, the terraces facing the heath, and surrounding residential streets. Article 4 Directions restrict most permitted development rights. Planning permission and Heritage Statements are required for external alterations, and Lewisham's (or Greenwich's) conservation officers scrutinise proposals carefully.
Georgian and Victorian heritage: Blackheath's Georgian townhouses and Victorian villas are among the finest in south-east London. Many are individually listed, requiring Listed Building Consent for internal and external works. Our MCIAT-chartered team produces the detailed architectural drawings and Heritage Impact Assessments that listed building applications demand.
Span developments: Blackheath is home to several Span estates — the pioneering modernist housing developments designed by Eric Lyons in the 1950s-60s. These estates have their own design guidelines and management companies. Any alterations must respect the original design language. We understand the Span aesthetic and prepare proposals that satisfy the estate management companies.
Dual-borough complexity: Properties on the west side of the heath generally fall under Lewisham Council, while those on the east may be in Greenwich. The two boroughs have different planning policies and conservation approaches. We confirm the relevant authority and tailor applications accordingly.

Start a free quoteAlmost certainly yes for external works. The Blackheath Conservation Area removes most permitted development rights through Article 4 Directions. Even replacement windows, roof changes, and some rear extensions require planning permission with a Heritage Statement. Our MCIAT-chartered team specialises in conservation-area applications in Blackheath.
Blackheath straddles Lewisham and Greenwich. The borough boundary roughly follows the A2. Properties to the west generally fall under Lewisham; those east under Greenwich. The two councils have different planning policies. We confirm your authority and adapt the application accordingly.
Span estate alterations must respect the original Eric Lyons design. Most changes require estate management approval in addition to planning permission. We understand the Span design principles and prepare proposals that satisfy both the estate management company and the planning authority.
Listed Building Consent is required for any works that affect the character of a listed building, whether internal or external. It is a separate application from planning permission. Our team prepares detailed drawings, Heritage Impact Assessments, and material schedules to the standard expected for listed building applications.
