Planning Permission in Southwark

The London Borough of Southwark is one of the capital’s most dynamic and architecturally varied areas. From the historic streets of Bermondsey and Dulwich Village to the modern regeneration zones around Elephant & Castle, Canada Water, and London Bridge, Southwark blends heritage with rapid development. This diversity creates a planning environment that is both opportunity rich and highly regulated. Homeowners benefit from strong investment and growth, but planning applications must be carefully prepared to meet Southwark’s expectations around design, neighbour amenity, sustainability, and heritage protection.
Whether you’re planning a rear extension, loft conversion, internal reconfiguration, or a more ambitious redevelopment, Southwark requires proposals to be thoughtful, well justified, and aligned with the borough’s detailed planning policies.

Understanding Southwark’s Planning Environment

Southwark is characterised by a mix of historic neighbourhoods, suburban streets, and high density urban areas. This means planning decisions are influenced by a wide range of factors, including conservation, flood risk, neighbour amenity, and design quality.
The borough contains several conservation areas, including Dulwich Village, Camberwell Grove, Bermondsey Street, and Peckham Rye. These areas are protected for their architectural and cultural significance, meaning external alterations must preserve or enhance local character. Proposals affecting listed buildings or historic streetscapes require careful justification and may need heritage statements.
Neighbour amenity is a major consideration in Southwark. Extensions must be designed to avoid harming daylight, sunlight, privacy, or the sense of openness enjoyed by neighbouring properties. Even modest proposals may require detailed analysis, especially in terraced streets or areas with closely spaced buildings.
Flood risk is another key factor. Areas near the Thames, Rotherhithe, and parts of Bermondsey may require flood risk assessments or design measures to mitigate potential impacts.
Southwark also places strong emphasis on sustainability. The borough encourages energy efficient design, high quality materials, and proposals that reduce carbon impact. This can influence glazing choices, insulation, and the overall design approach.

Key Local Planning Considerations in Southwark

1. Conservation Areas
Southwark contains numerous conservation areas. Proposals must preserve or enhance local character, affecting:
• Rooflines
• Windows and doors
• Materials
• Extensions
• Boundary treatments
2. Neighbour Amenity
Due to the borough’s density, neighbour impact is a major factor. Extensions must demonstrate minimal impact on:
• Daylight
• Sunlight
• Privacy
• Sense of enclosure
3. Flood Risk
Properties near the Thames or in low lying areas may require flood risk assessments and resilient design measures.
4. Roof Alterations
Loft conversions are common but must respect roof form, materials, and visibility from the street. Roof terraces are often restricted.
5. Listed Buildings & Heritage
Historic areas such as Dulwich Village and Bermondsey require sensitive, well justified proposals.
