UK-based Weston Williamson Architects will design the revamp of London's Victoria Station, which is expected to double its size on completion.
The practice will deliver the ВЈ700m ($1bn) overhaul for Transport for London.
BAM Nuttall and Taylor Woodrow have been appointed to build the project in phases, which include the creation of a new entrance and ticketing hall.
Work is expected to begin in 2011 and finish in 2016, according to architectsjournal.co.uk .
