Hammersmith sits where the Thames curves south and London's grandest riverside terraces meet quiet residential streets. Our architects understand every LBHF conservation area, every riverside planning constraint, and the careful balance between period character and modern living that W6 demands.
Hammersmith is a place of contradictions that somehow resolve into one of West London's most appealing neighbourhoods. The roar of traffic around Hammersmith Broadway gives way, within a few hundred yards, to the silence of Upper Mall and Lower Mall — a stretch of Georgian riverside houses that ranks among London's most beautiful domestic architecture. Hammersmith Bridge, the ornate suspension bridge designed by Joseph Bazalgette in 1887, frames views up and down the Thames that have barely changed in a century.
Behind the riverside, the residential streets tell the story of Hammersmith's growth from a Thames-side hamlet to a prosperous Victorian suburb. Brackenbury Village — the grid of streets south of Goldhawk Road — is a textbook example of late-Victorian terrace housing: bay-fronted, generously proportioned, and now among the most sought-after streets in W6. Around Ravenscourt Park, larger Edwardian and Victorian houses line quiet, tree-planted avenues. St Peter's Square, an early Victorian development of elegant succeed houses around a private garden, offers a taste of Belgravia west of Hammersmith Broadway.
For homeowners in W6, the challenge is to honour this varied architectural heritage while creating homes that work for contemporary life. The London Borough of Hammersmith and Fulham takes a moderate but considered approach to planning — riverside properties and conservation area houses face tighter controls, while the borough's general planning policies offer reasonable scope for sensitive extensions, loft conversions, and internal remodelling. Our architects understand what LBHF will support and how to design schemes that respect Hammersmith's character while maximising space and light.

Hammersmith falls under the London Borough of Hammersmith and Fulham, which takes a moderate but considered approach to residential planning. Unlike some inner-London boroughs, LBHF generally supports well-designed extensions and alterations — but properties within conservation areas or on the riverside face significantly tighter controls. The borough's four main conservation areas in Hammersmith — Hammersmith Mall, Bradmore, St Peter's Square, and Ravenscourt Park — protect the area's most architecturally significant streets.
For Hammersmith's Victorian terraces, rear extensions under permitted development rights remain one of the most popular and cost-effective ways to add space. Loft conversions with rear dormers are generally achievable outside conservation areas. Riverside properties, however, are subject to more restrictive policies that protect the Thames setting, views, and the character of the Mall's Georgian frontages. Our architects have extensive experience with LBHF's planning team and understand where the boundaries of the permissible lie.

Victorian terraces outside conservation areas benefit from PD rights for rear extensions up to 6m (detached) or 3m (terraced/semi). Loft conversions with rear dormers also generally permitted.
Properties on Upper Mall and Lower Mall face additional scrutiny. Thames-side setting, views, and the Georgian character of the Mall are protected by specific policies.
LBHF offers pre-application services. Recommended for conservation area schemes, riverside properties, and any works requiring planning permission in W6.
Realistic cost ranges for the most common project types in Hammersmith. Conservation area and riverside properties typically attract a 10–20% premium for specialist design and materials.

Parts of Hammersmith are. The borough has four main conservation areas in W6: Hammersmith Mall (covering the riverside), Bradmore, St Peter's Square, and Ravenscourt Park. Properties within these areas face additional planning controls on external alterations. Many residential streets outside conservation areas benefit from standard permitted development rights.

In most cases, yes. Victorian terraces outside conservation areas can typically be extended under permitted development rights — up to 3m for terraced houses. Within conservation areas, planning permission is required but LBHF generally supports well-designed extensions that respect the character of the property and streetscape. Our architects design extensions that maximise your chances of approval.
Loft conversions in W6 typically cost £55,000–£120,000 depending on the type (rear dormer, L-shaped dormer, or mansard) and specification. Victorian terraces in Brackenbury Village and around Ravenscourt Park are particularly well suited to loft conversions. All our projects are delivered on fixed-price contracts.
Riverside properties on Upper Mall and Lower Mall face more restrictive planning policies due to the conservation area designation and the Thames-side setting. External works must preserve the Georgian character, and new development that affects views of or from the river is closely scrutinised. Our architects have specific experience with riverside properties and LBHF's requirements.
It depends on whether your property is in a conservation area and the size of the extension. Outside conservation areas, single-storey rear extensions up to 3m (terraced) or 4m (semi-detached) can typically be built under permitted development. Within conservation areas, planning permission is usually required. Our architects assess your specific situation during the initial consultation.
Yes. Our in-house RIBA architects manage all planning and conservation area applications from initial feasibility through to approval.
