Canary Wharf railway station, designed by Foster + Partners, is currently under construction in Canary Wharf, east London, as part of the Crossrail project. Construction began in May 2009, its above-ground floors (containing services and retail units, topped by a roof garden) opened in 2016, and is expected to start receiving railway services in 2018. During the project's development the station was named Isle of Dogs, before the current name was adopted. Construction will cost an estimated £500 million to complete.[2] The design includes Crossrail Place, a roof garden.
