Full House Renovation in Hammersmith
A whole property taken back and rebuilt to a single standard, managed by one team from first drawing to final handover.
ExploreExtensions, loft conversions and refurbishment across W6, from Brackenbury Village to the Hammersmith riverside.
Hammersmith shares its council with Fulham but not its housing stock. W6 is more varied: tight Victorian terracing in Brackenbury Village, larger stucco and villa property around Ravenscourt Park, riverside houses along the Mall and a good deal of purpose built flats.
That variety means the right project differs street by street rather than following a single pattern, and the consent position varies with it. We assess each property rather than applying a template.

Hammersmith and Fulham has designated a considerable amount of W6, including Brackenbury, Ravenscourt Park and the riverside. Designation restricts elevations, roof alterations and windows, so the address matters.
Tight terraces in Brackenbury take side returns and dormers. The larger villa property around Ravenscourt Park supports double storey extensions and hip to gable conversions. The approach is not interchangeable.
Property along the Hammersmith riverside sits within Environment Agency flood zones, which affects basement work and can affect ground floor extension design. We check the zone as part of feasibility.
In the tighter terracing of Brackenbury Village and the streets off Goldhawk Road, the work is familiar: side return infills, rear extensions and dormer loft conversions, all aimed at the same problem of a narrow dark kitchen and a bedroom short.
Around Ravenscourt Park and towards Stamford Brook the houses are larger and often semi detached with side access and hipped roofs, which opens up hip to gable conversions and double storey extensions that the smaller stock will not support.
Brackenbury is a compact grid of late Victorian terraces between Goldhawk Road and King Street, and it is a conservation area. The houses are smaller than the Fulham equivalent and the streets are narrower, which affects both what can be built and how it gets delivered.
Designation means front elevations, roof coverings and windows are controlled. Rear alterations are generally achievable, but anything visible from the street needs consent. Access is the practical constraint: narrow frontages and controlled parking mean skip permits and bay suspensions have to be arranged in advance.
W6 has a high proportion of converted and purpose built flats, and there the lease governs as much as the planning system. Most leases require written freeholder consent for alterations, and many restrict changes to layout, floor finishes and anything affecting the building services.
Sound transmission between flats is the usual sticking point, and hard flooring is commonly restricted or subject to an acoustic underlay specification. We work to those specifications and provide the documentation the managing agent will want to see.
The Victorian stock here has the same underlying construction as the rest of south west London: solid brick walls with no cavity, shallow foundations, lath and plaster ceilings and lime plaster on the walls.
The recurring issues follow from that. Cement render applied over solid brick traps moisture and causes the blown plaster we strip out. Gypsum will not bond durably to lime. Where the original construction is lime we repair in lime, because sealing a wall that was designed to breathe simply moves the damp somewhere less convenient.
The house is in a conservation area and we had been told by two other builders that what we wanted was impossible. NSPEC worked out what was achievable to the rear, got it through and built it properly.

ExploreA large amount of W6 is designated, including Brackenbury, Ravenscourt Park and the riverside, but coverage is not universal. Designation removes some permitted development rights and controls elevations, roofs and windows. We confirm the position on your specific address before quoting.
Flats have no permitted development rights, so any extension needs full planning permission, and your lease will almost certainly require freeholder consent as well. Internal alterations are more straightforward but structural changes still need building control approval and usually the freeholder's agreement.
Rear alterations generally are: side return infills, rear extensions and rear dormers. Front elevations, roof coverings and front facing windows are controlled by the conservation area designation. We will tell you specifically what your property allows on the free visit.
All of W6: Brackenbury Village, Ravenscourt Park, Stamford Brook, Shepherd's Bush borders, King Street, the Grove and the riverside. We also cover neighbouring Fulham, Chiswick, Kensington and Barnes.
