Chelsea Harbour is a contemporary mixed-use development in West London, situated in its Sands End area, along Chelsea Creek, the historic southeastern boundary of the London Borough of Hammersmith and Fulham with the southwestern boundary of the Royal Borough of Kensington and Chelsea, and opposite the site of the old Lots Road Power Station in Chelsea. The development consists of luxury apartments, the Chelsea Harbour Marina and the Chelsea Harbour Design Centre and a hotel, 'the Chelsea Harbour Hotel'. History "Chelsea Harbour" stands on land that was once the 28-acre estate of Sandford Manor House. Among other occupants, it is reputed to have been the residence of Nell Gwyn. At the start of the 19th-century, it was in decline and was bought by a gas company. Part of the land was used as a Victorian-era railway coaling dock on the River Thames. Latterly it had been a coal yard for predecessor companies of British Rail. The 20-acre site lies in a triangle bounded by the Thames and Counter's Creek to the south and east, and to the west by the West London Line (Overground Network and National Rail) on a viaduct. At the inception of the redevelopment, the Conservative-led Hammersmith and Fulham Council, having granted planning permission, approached the Boundary Commission to have it re-designated as part of the Royal Borough of Kensington and Chelsea. The Commission reported in 1992 proposing a shift of boundary to the middle of the West London Line rail tracks. In the event, the Royal Borough passed on the offer of Chelsea Harbour in the then Leader's following terms: The Royal Borough has completed its submissions to the Boundaries Commission. No suggestion that we should take Chelsea Harbour into this authority was among them. That will remain our position. (Nicholas Freeman) Regeneration Chelsea Harbour was designed by architects Moxley Jenner & Partners, developed by Mansford, with Bovis Homes Group serving as project management consultants. It was the biggest single construction project in the United Kingdom for decades. The original design was for 16 buildings covering some 14 acres. Only 12 buildings were completed due to a downturn in the UK economy during the construction period. Remediation When planning permission was granted on 15 April 1986, the whole site, including the lock, was derelict. Both the Coal Dock and the lock had been infilled with contaminated materials, which had to be excavated and disposed of. The
