Why Hammersmith & Fulham Homeowners Choose Crown Architecture
The London Borough of Hammersmith and Fulham is one of inner west London’s most dynamic residential boroughs. Its relatively compact geography — stretching from the studios of Shepherd’s Bush (W12) in the north to the riverside streets of Fulham (SW6) and the elegant Victorian terraces of West Kensington (W14) — encompasses some of the capital’s most architecturally interesting and keenly contested residential streets.
Hammersmith and Fulham attracts a sophisticated homeowning community: media professionals in Brook Green and Brackenbury Village, families in the Eel Brook Common area of Fulham, creative and tech workers drawn to the regenerating White City and Shepherd’s Bush area. What unites them is a demand for high-quality architectural design that respects the borough’s rich Victorian heritage while meeting the requirements of contemporary living.
At Crown Architecture, we have delivered numerous successful projects across LBHF — from side-return extensions in Fulham’s tightly packed terraces to substantial loft conversions on the larger Victorian and Edwardian houses of Brook Green. Our RIBA-chartered team understands the borough’s planning culture, its distinctive conservation areas, and the design sensibilities of the communities who live here.
Our Services in Hammersmith & Fulham
Side Return and Rear Extensions
The long, thin plots of LBHF’s Victorian terraces — particularly prevalent in SW6, W6, and W14 — are ideally suited to side-return extensions. Filling in the narrow side passage beside a terraced house can add 15–25m² of open-plan kitchen and dining space, transforming the ground floor without touching the garden. We design these extensions to maximise natural light, using rooflights, full-width glazed doors, and carefully considered material palettes.
Loft Conversions
Hammersmith and Fulham’s Victorian terrace rooflines offer excellent loft conversion potential. A rear dormer adds a bedroom and bathroom; a hip-to-gable or full mansard conversion can add two storeys in the right circumstances. We handle feasibility, structural engineering coordination, planning, and Building Regulations.
White City and Shepherd’s Bush Residential
The ongoing White City regeneration (W12) creates exciting opportunities for contemporary residential architecture. Crown Architecture offers design services for new-build residential projects and for the conversion and extension of existing buildings in the W12 area.
Full Refurbishment
Many of LBHF’s Victorian and Edwardian properties benefit from comprehensive remodelling — replanning ground floors, upgrading Victorian bathrooms and kitchens, adding new basement extensions, and integrating modern services within period shells. Our full-refurbishment service combines architectural precision with a strong interior design sensibility.
Planning in Hammersmith & Fulham
LBHF Planning Authority
All planning applications in the London Borough of Hammersmith and Fulham are submitted via the Council’s planning portal at public-access.lbhf.gov.uk. LBHF processes applications under the NPPF, the London Plan (2021), and the LBHF Local Plan (adopted 2018).
Key local plan policies relevant to residential extensions include:
- DC1 — General Development Considerations
- DC2 — Design
- DC8 — Conservation and Heritage
- H2 — Protecting Residential Amenity
Conservation Areas in Hammersmith & Fulham
LBHF has over 30 conservation areas. Key areas for residential projects include:
Brook Green Conservation Area — Brook Green is one of LBHF’s most desirable residential addresses, centred on the long strip of green from Hammersmith Road to Shepherd’s Bush Road (W6). The surrounding streets feature Victorian and Edwardian terraces and semi-detached houses. The conservation area appraisal emphasises the importance of the green’s soft landscaping and the consistent Victorian street frontages. Extensions must respect the scale and character of the original buildings.
Fulham Conservation Area — Covering large swathes of the SW6 postal district, including the area around Eel Brook Common and the streets south of Fulham Road. Victorian and Edwardian terraces predominate. The conservation area guidance sets detailed requirements for materials, windows, and boundary treatments.
Ravenscourt Park Conservation Area — A residential area to the west of Ravenscourt Park (W6), featuring large Victorian and Edwardian houses. The setting — generous plots, mature trees, proximity to the park — creates an unusually high-quality suburban character. Design guidance is correspondingly demanding.
Sands End Conservation Area — Located in southern Fulham (SW6), Sands End is one of the borough’s up-and-coming areas, with late-Victorian artisan terraces undergoing significant investment. The conservation area appraisal notes the importance of the area’s modest scale and the character of individual streets such as Wandsworth Bridge Road.
Shepherd’s Bush and White City
The W12 area around Shepherd’s Bush and White City is subject to the White City Opportunity Area planning framework, which encourages high-quality residential and mixed-use development. The Bush Theatre, the BBC Media Village, and the growing Imperial College White City campus make this a particularly interesting planning context.
Planning Timelines
Standard householder applications in LBHF are typically determined within 8–10 weeks of validation. Conservation area applications may take slightly longer. LBHF’s planning team operates a pre-application advice service (charged), which Crown Architecture strongly recommends for all conservation area projects.
Popular Projects in Hammersmith & Fulham
Side Return Extension — Rowena Crescent, SW6
A Victorian mid-terrace in Fulham, on a classic long-thin plot typical of the SW6 streets south of King’s Road. The owners wanted to extend into the side return and create a new open-plan kitchen-dining space opening onto the rear garden. Crown Architecture designed a fully glazed side-return extension with a rooflight running the full length of the new space, bifold doors to the garden, and a carefully considered kitchen with island. Planning consent was secured from LBHF in 8 weeks. The extension added 19m² and transformed the ground floor living experience.
Loft Conversion and Rear Extension — Brackenbury Road, W6
A four-bedroom Edwardian semi in Brackenbury Village — one of LBHF’s most coveted residential enclaves. The owners wished to add a master bedroom suite at loft level and expand the kitchen on the ground floor. Crown Architecture designed a rear dormer loft conversion and a modest single-storey rear extension, both in materials sympathetic to the Edwardian original. The Brackenbury Village Conservation Area appraisal was followed closely, and consent was granted at first submission after a positive pre-application response.

Frequently Asked Questions — Architect in Hammersmith & Fulham
Q: Do I need planning permission to extend my house in LBHF?
A: Many extensions fall within Permitted Development rights, but LBHF’s numerous conservation areas may restrict these rights. Crown Architecture assesses every property at the feasibility stage.

A: Standard applications are typically determined within 8–10 weeks. Conservation area applications may take longer. Pre-application advice is recommended for complex projects.
Q: Can I extend my Victorian terrace in Fulham under permitted development?
A: Outside conservation areas, many Fulham terraces can be extended under Permitted Development (subject to size limits). In conservation areas like Fulham or Sands End, full planning permission is required for most external works.
Q: What is the planning situation for White City and Shepherd’s Bush?
A: The W12 area is subject to the White City Opportunity Area planning framework, which has specific design requirements for new development. Crown Architecture has experience working within this planning framework.
Q: What are the conservation areas in LBHF?

Q: How much does a side return extension cost in LBHF?
A: Side return extensions in LBHF typically cost £2,200–£3,500/m² to construct, depending on specification. Architectural fees for a full service are typically 8–12% of construction cost. Crown Architecture provides fixed-fee quotations.
Q: Can I do a basement extension in Hammersmith & Fulham?
A: LBHF has a detailed policy on basement extensions (Policy DC1 and supplementary guidance). Proposals are assessed carefully, particularly in conservation areas and where structural or drainage issues may arise. Crown Architecture has experience with LBHF basement extension applications.
Q: Do I need a party wall agreement for my extension in LBHF?
A: The Party Wall etc. Act 1996 applies to works affecting shared walls or requiring excavation close to neighbouring foundations. This is common in LBHF’s densely packed Victorian terraces. Crown Architecture advises on party wall obligations.
Local Character — Hammersmith & Fulham
Few London boroughs pack as much variety into so small an area as Hammersmith and Fulham. Fulham (SW6) has evolved from a working-class riverside community into one of the most fashionable addresses in west London, with New King’s Road and Fulham Road lined with boutiques, restaurants, and coffee shops. The streets around Eel Brook Common and Parsons Green — Broomhouse Road, Peterborough Road, Stephendale Road — are typical of the substantial Victorian family homes that attract buyers from across the capital.
Brackenbury Village (W6) is a particular gem — a quiet residential enclave of Edwardian terraces just minutes from Hammersmith Broadway, loved for its local cafes and independent shops. Brook Green (W6) combines a village green atmosphere with excellent access to Kensington and the West End. West Kensington (W14) offers larger Victorian properties at slightly lower prices than neighbouring Kensington.
Shepherd’s Bush (W12) is in full regeneration, with the Westfield London shopping centre, the restored Bush Theatre, and the White City development attracting new residents and investment. The area’s transformation over the past decade has been remarkable, and its accessibility — Central line, Overground, and Circle/District at Hammersmith — makes it increasingly appealing.
Transport links are excellent throughout the borough: Hammersmith station (District, Piccadilly, and Circle lines), Fulham Broadway (District line), Shepherd’s Bush (Central line), and Ravenscourt Park (District line) all provide fast access to central London.
