Plans drawn up by architects Stanton Williams have been chosen for a new public square as part of Network Rail's £500m redevelopment of King's Cross station.

The London-based firm was selected after holding off more than 100 architects and urban design practices who submitted designs for the project, which will create one of the capital's largest public squares. Network Rail has set aside around £6m for the 7,000sq m (75,347sq ft) public square, which is due for completion in 2013 and will be able to accommodate up to 100,000 rail passengers each day.

Stanton Williams will work on the scheme alongside architect John McAslan and Partners and contractors Vinci, Kier, Arup and Carillion as part of Network Rail's King's Cross project team. Alan Stanton of Stanton Williams said: "The design will address the challenge of integrating the legacy of existing structures on the site to create an environment which functions seamlessly for the public and makes an important contribution to the regeneration of the surrounding area."

Victoria Pender, Network Rail group director and judging panel member, added: "Network Rail's redevelopment of the station will transform King's Cross and provide a wonderful gateway to London for everyone who uses the station." Image: Network Rail
