One Nine Elms is a mixed-use skyscraper in Nine Elms, London. It was originally developed by Wanda One, a UK subsidiary company of Dalian Wanda, until they sold the project to R&F Properties, another Chinese firm in 2018. It was designed by architects Kohn Pedersen Fox (KPF). The development replaces two towers on the site built in the 1970s called Market Towers and forms part of a wider redevelopment of the Nine Elms area of London. The development consists of two towers: the 57-storey City Tower (199) contains 334 homes, while the 42-storey River Tower contains a 203-room Park Hyatt luxury hotel (156 m) and 103 luxury Park Hyatt-branded apartments. Upon completion in 2024, One Nine Elms became one of the tallest residential developments in London and the United Kingdom.
