Introduction
SE22 is the postcode of East Dulwich — one of south London’s most popular and architecturally coherent family neighbourhoods, straddling the boundary between the London Borough of Southwark and the London Borough of Lewisham. The area is characterised by its impressive stock of Edwardian terraces and semi-detached houses, its leafy streets, its proximity to Dulwich Park and the cultural anchor of Dulwich Picture Gallery.
The housing stock of SE22 is predominantly Edwardian — built between 1900 and 1914, in a variety of Arts and Crafts-influenced and vernacular revival styles. These are generally larger than Victorian terraces: three-storey properties with bay windows, decorative tile-hanging, generous rear gardens and good ceiling heights. They respond very well to architectural intervention, offering strong potential for rear extensions, loft conversions and internal reconfigurations that create the generous, light-filled family spaces that modern owners want.
East Dulwich has experienced sustained popularity with young families and professional owner-occupiers over the past two decades, driven by the quality of the housing stock, the quality of local schools, the open spaces and the village atmosphere around Lordship Lane. Property values have risen consistently, making investment in architectural improvement increasingly attractive. The East Dulwich Conservation Area protects parts of the postcode’s most characterful streetscapes.
Crown Architecture works extensively in SE22, delivering rear extensions, loft conversions and comprehensive refurbishments to Edwardian terraced houses throughout East Dulwich. We understand the planning frameworks of both Southwark and Lewisham, the specific character of the East Dulwich housing stock and the design standards that both councils apply. Our track record of delivering excellent results for East Dulwich families makes us a natural choice for architectural projects in SE22.
Our Services
Rear Extensions: Edwardian terraces in SE22 are ideally suited to rear extensions. We regularly design single-storey rear extensions of 20–30 sq m that create open-plan kitchen-dining-family rooms with glazed rear elevations opening onto rear gardens. The generous plot depths typical of SE22 allow for extensions of real quality without loss of useful garden space.
Loft Conversions: The pitched Edwardian roofs of SE22 offer excellent loft conversion potential. Rear dormers are the standard approach, adding a top-floor bedroom suite with en-suite bathroom that adds significant value and provides essential space for growing families. We design loft conversions to suit the character of each house and comply with applicable planning requirements.
Side-Return Extensions: Many SE22 Edwardian terraces have side returns that, when enclosed, can dramatically widen the ground-floor plan. Side-return extensions are a cost-effective way to gain meaningful additional space.
Full Refurbishments: Crown Architecture designs comprehensive refurbishments for SE22 properties, restoring original Edwardian features — tile fireplaces, original floorboards, stained glass — while delivering contemporary kitchens, bathrooms and services.
Planning Advice and Pre-Application Service: For clients at an early stage, we provide pre-application feasibility advice and facilitate meetings with Southwark or Lewisham planning officers.
Planning Authority & Local Planning Context
SE22 straddles London Borough of Southwark (for the northern part of the postcode around Lordship Lane and north) and London Borough of Lewisham (for the southern parts). Crown Architecture identifies the correct authority for each address.
East Dulwich Conservation Area: Parts of SE22 fall within the East Dulwich Conservation Area, protecting the most characterful Victorian and Edwardian streetscapes in the postcode. Within this designation, most extensions and external alterations require full planning applications. Proposals must respect the character of the conservation area in terms of materials, proportions and relationship to the street.
Permitted Development in SE22: For properties outside conservation areas and not subject to Article 4 Directions, a wide range of extensions and loft conversions may be achievable as permitted development. Crown Architecture advises on PD eligibility and obtains Lawful Development Certificates where appropriate.
Typical Planning Issues in SE22: Securing permission for rear extensions in conservation areas; managing daylight and overlooking on densely-built Edwardian terraces; designing loft conversions that satisfy council design standards; and meeting requirements for sustainable design and biodiversity net gain.
Project Examples
Lordship Lane Edwardian Terrace, SE22: A three-storey Edwardian terrace on Lordship Lane was the subject of a rear extension and loft conversion by Crown Architecture. The single-storey rear extension of 28 sq m created a new open-plan kitchen-dining-family room with a flat glazed roof, bifold doors to the rear garden and a new utility room. The rear dormer loft conversion added a principal bedroom suite with en-suite bathroom. The project fell within the East Dulwich Conservation Area, requiring a full planning application to Southwark. Materials — stock brick, zinc flashings and timber windows — were carefully chosen to satisfy Southwark’s conservation area requirements, and planning was approved within the standard period.
Grove Vale Semi-Detached House, SE22: A large Edwardian semi-detached house on Grove Vale was the subject of a comprehensive refurbishment and rear extension by Crown Architecture. The rear extension of 35 sq m was achieved under permitted development (the property being outside the conservation area), and a Lawful Development Certificate was obtained before works commenced. The refurbishment included restoration of original tile fireplaces, new kitchen and bathrooms, and a full upgrade of services. The project was delivered within an 8-month programme.

Frequently Asked Questions
1. Which council handles planning in SE22?
SE22 spans Southwark and Lewisham. The applicable authority depends on the exact address. Crown Architecture identifies the correct planning authority at the outset of every project.
2. Do I need planning permission for a rear extension in the East Dulwich Conservation Area?
Yes. Within the East Dulwich Conservation Area, most rear extensions require full planning permission. Outside the conservation area, extensions may fall within permitted development rights, subject to dimensional limits.
3. What size of rear extension can I achieve on my SE22 Edwardian terrace?
Under permitted development (with prior approval under the Larger Home Extensions procedure), up to 6m depth is possible on a semi-detached or terraced house. Standard PD allows up to 3m without prior approval. Full planning permission may allow greater depth, subject to planning merits.
4. Can I do a loft conversion on my SE22 Edwardian property?
Yes. Rear dormer loft conversions are common in SE22. Within the conservation area, a full planning application is required. Outside the conservation area, some loft conversions may be achievable under permitted development.
5. Do I need a party wall agreement for my SE22 extension?
If works involve a shared wall or excavation within 3m of a neighbour’s foundations, the Party Wall Act applies. Crown Architecture advises on party wall obligations for every project.
6. What materials does Southwark require for SE22 conservation area extensions?
Southwark requires materials sympathetic to the Edwardian character of the street. Stock brick, slate or zinc roof coverings, and timber or aluminium window frames are typical. Crown Architecture advises on appropriate specifications.
7. Can I restore original Edwardian features in my SE22 house?
Yes. Restoring original features — tile fireplaces, sash windows, original floorboards — is generally not subject to planning control for internal works. External restoration may require planning permission within conservation areas.
8. How much does an architect cost for an SE22 project?
For typical rear extensions and loft conversions in SE22, our fees start from around 8–12% of construction cost for a full service. Fixed-fee planning packages are also available.
Local Character
SE22 has a warm, village-like character defined by its quality Edwardian streets and its proximity to excellent green spaces. Lordship Lane is the postcode’s main commercial artery — a well-regarded independent high street with restaurants, delis, bookshops and a popular weekly market. Grove Vale runs parallel as a quieter residential street of substantial Edwardian semis. Underhill Road and Goose Green are further residential streets where Crown Architecture has completed multiple projects.
East Dulwich station (Overground, London Bridge to Crystal Palace line) provides connections to London Bridge, the City and Crystal Palace. Bus routes on Lordship Lane and Forest Hill Road provide wider connectivity.
Dulwich Park — one of south London’s finest parks — is close to the southern end of SE22, with the Dulwich Picture Gallery nearby as one of south London’s great cultural assets.
