200+ projects completed | 97% planning approval rate | RIBA-aligned practice | 5★ Google reviews
Crown Architecture is a London-based architectural practice with strong experience delivering residential projects across the London Borough of Bexley. From the 1930s semis of Bexleyheath and Welling to the fine Victorian properties near Bexley Village and the more modern estates of Erith and Slade Green, we bring genuine local knowledge and planning expertise to every project.
Why Homeowners in Bexley Choose Crown Architecture
The London Borough of Bexley sits at the south-eastern edge of Greater London, bordering Kent. Its residential character is dominated by the inter-war and post-war suburban expansion that produced a generous stock of detached and semi-detached houses across DA5 (Bexley), DA6 (Bexleyheath), DA7 (Bexleyheath North), DA14 (Sidcup), DA15 (Sidcup and Foots Cray) and SE2 (Abbey Wood).
In DA6 and DA7 (Bexleyheath), the housing is predominantly 1930s semi-detached and detached, with regular plot sizes and rear gardens that accommodate meaningful extensions. Bexleyheath Broadway is the commercial heart of the borough, and the residential streets around it are popular with families seeking good value relative to inner London. Our clients here typically seek single or double-storey rear extensions or hip-to-gable loft conversions to maximise space.
DA14 (Sidcup) and DA15 (Sidcup and Foots Cray) offer a similar character, with slightly larger plots in some areas — particularly around Sidcup High Street and the fine residential streets of Foots Cray. Sidcup is served by Southeastern rail to London Charing Cross and Cannon Street, making it popular with commuters.
DA5 (Bexley) is perhaps the most characterful part of the borough. Bexley Village itself retains historic buildings, including listed structures, alongside later residential development. The Bexley Village Conservation Area is carefully managed and our experience in heritage-led design is regularly called upon here.
SE2 (Abbey Wood) is undergoing significant transformation following the opening of the Elizabeth line station at Abbey Wood, which provides rapid connections to the City and beyond. Demand for quality home improvements is growing here as property values rise.
Our Architectural Services in Bexley
Rear and Side Extensions
Extensions are the most popular project across all Bexley postcodes. The inter-war housing stock typically offers good rear garden depth, allowing extensions of 4–6m while retaining outdoor space. We design extensions that create modern, light-filled living spaces through rooflights, large glazed openings and carefully considered connections to the garden. We handle all planning applications, prior approvals and building regulations documentation.
Loft Conversions
The 1930s semi-detached house is ideal for a hip-to-gable loft conversion, which widens the usable floor area by converting the hipped end to a vertical gable. Combined with a rear dormer, this creates a substantial bedroom suite. We have completed numerous such conversions across DA6, DA7 and DA14 and understand the structural requirements and planning implications thoroughly.
New Residential Builds
Bexley’s relatively generous plot sizes create opportunities for backland residential development. We carry out planning feasibility appraisals and design new dwellings that respect the suburban character of the borough.
Bexley Village Conservation Area Projects
We have specific experience working in Bexley Village Conservation Area, where design expectations are high and a Heritage Statement is required. Our heritage-led approach consistently produces positive planning outcomes.
Refurbishments
Older properties in Bexley — particularly in Bexley Village and the conservation-adjacent areas — benefit from thoughtful refurbishment. We manage layout redesigns, structural alterations and fit-out coordination.
Planning in Bexley: What You Need to Know
Planning authority: London Borough of Bexley
Planning portal: bexley.gov.uk/planning
Bexley Council operates its own planning portal and aims to determine householder applications within 8 weeks. Pre-application advice is available for larger or more sensitive projects.
Conservation Areas in Bexley
Bexley has several designated conservation areas:
- Bexley Village Conservation Area — covers the historic core of Bexley Village, including listed buildings along High Street and the River Cray. Design expectations are high and all works must respect the historic character of the village.
- Crayford Conservation Area — centred on the historic market town of Crayford, with listed buildings including Crayford Manor House. Extensions and alterations require sensitive design.
- Erith Conservation Area — focuses on the historic core of Erith town centre. Erith is undergoing significant regeneration and new development is assessed against both conservation policies and regeneration aspirations.
Article 4 Directions
Article 4 Directions apply in parts of Bexley’s conservation areas. We confirm the position for your specific property at the outset of every project.
Local Plan
Bexley’s Local Plan guides all development in the borough, with policies on residential extensions, conservation areas, and the significant regeneration projects in Erith and the Thames-side areas. We reference these policies directly in our submissions.
Case Studies
Hip-to-Gable Loft and Rear Extension, Maiden Lane, Crayford, DA1 4BN
A couple on Maiden Lane in Crayford wanted a hip-to-gable loft conversion combined with a single-storey rear extension to create a home office, fourth bedroom and enlarged ground-floor living space. We combined both elements in a single project, coordinating planning and building regulations applications simultaneously. Planning permission was obtained in 7 weeks and the project completed in 14 weeks, adding 40 sq m of usable space.
Conservation Area Extension, High Street, Bexley Village, DA5 1AF
A homeowner in Bexley Village sought to extend their 1920s terraced cottage at the rear to create an enlarged kitchen. The property sits within the Bexley Village Conservation Area. We designed a single-storey extension using matching London stock brick, lime mortar and clay roof tiles, supported by a Heritage Statement addressing Bexley’s conservation area guidance. The conservation officer confirmed the design was acceptable and planning permission was granted at first submission.

Frequently Asked Questions
Q: Do I need planning permission for a rear extension in Bexley?
A: In most of Bexley outside conservation areas, permitted development allows single-storey rear extensions up to 4m on a detached house (3m on a semi or terrace) without planning permission, subject to prior approval for larger extensions. Conservation areas and Article 4 Directions may restrict these rights.
Q: What is special about Bexley Village Conservation Area?
A: Bexley Village is one of the most intact historic villages in Greater London, with a cluster of listed buildings along High Street and around the River Cray. The Council expects all new works within the conservation area boundary to respect the historic character. Extensions must use traditional materials and forms.
Q: How does the Elizabeth line affect planning in Abbey Wood?
A: The Elizabeth line has driven significant demand and investment in SE2. Planning policy in Abbey Wood supports higher-density development near the station, while the existing residential streets around it are expected to retain their suburban character. We advise on the planning context for your specific location.
Q: How long does planning take in Bexley?
A: Bexley Council’s target is 8 weeks from validation for householder applications. Conservation area applications may involve consultation with the heritage officer, adding a small amount of time if the design needs discussion.
Q: Is a hip-to-gable loft conversion permitted development in Bexley?
A: The hip-to-gable element (altering the ridge and gable of the roof) requires planning permission as it changes the roof shape. The rear dormer element may be permitted development outside conservation areas. We handle both elements as part of our standard loft conversion service.
Q: What planning documents are needed for a Bexley conservation area application?
A: In addition to architectural drawings, a Heritage Statement explaining how the design respects the character and appearance of the conservation area is required. For listed buildings, a Listed Building Consent application must also be submitted. We prepare all required documents.
Q: Can I subdivide my large Bexley garden to build a new house?
A: This is possible in some circumstances, particularly where the plot is genuinely large and there is adequate access. Bexley Council will assess the impact on the character of the street and on neighbouring amenity. We offer a planning feasibility appraisal before any commitment to a full application.
Q: How do I check if my Bexley property is in a conservation area?
A: Visit bexley.gov.uk/planning and use the interactive maps to check conservation area boundaries, or provide us with your address and we will confirm at our initial consultation.
Bexley’s Local Character
Bexley is served by Southeastern rail services from Sidcup, Albany Park, Bexley, Crayford and Barnehurst to London Charing Cross and Cannon Street. The Elizabeth line at Abbey Wood provides a fast connection to the City, Canary Wharf and West End.
Key residential areas include the historic Bexley Village with its riverside cottages, the family streets of Sidcup around Hatherley Road and Days Lane, the popular 1930s avenues of Bexleyheath around Watling Street, and the more modern residential streets of Welling. Foots Cray Meadows, Danson Park and Lesnes Abbey Woods provide substantial green-space assets, alongside the Thames waterfront in Erith.
