More than two thirds of people plumped for the practice's proposals following a three-way competition to find a design team to redevelop the neglected space outside Huddersfield station.
The firm's design for the square is being hailed as a sensitive and flexible solution which will 'accommodate activity from outdoor events to easy movement through the space for pedestrians, taxis and buses'.
There are also plans for new seating areas and a travel-information kiosk at the entrance to the station as part of the proposals, which will see the rerouting of Railway Street and the relocation of the existing statue of Huddersfield-born former prime minister Harold Wilson into the centre of the square.
Whitelaw Turkington was praised by the council for looking at 'the strong architectural heritage of the area' including the grand neo-Classical buildings surrounding the square and for creating a scheme 'inspired by history but that is contemporary in detail and style'.
Guy Denton, the director in charge of Whitelaw Turkington's Northern office, said: 'We're delighted to have won the public's vote and the council's backing - it's vital to have such positive support for the development of such an important public space.'
Construction is due to start early next year and to be completed by the end of 2008.
