Network Rail has shortlisted six architect firms to design a new public square at the heart of its £450m redevelopment of King’s Cross in London.

The new square will be bigger than Leicester Square, located on the site of the current Euston Road concourse, which will be demolished when the new station concourse is complete.

Network Rail and Camden Borough Council are working together on the redevelopment and have shortlisted:

- Field Operations with Buro Happold, Concepto, Macgregor Smith, Tomato

- Gehl Architects and Landscape Projects with a team comprising Martin Stockley Associates, Simon Fenton Partnership, four23, and Hansen & Henneberg.

- Gross.Max. Landscape Architects

- Gustafson Porter with Arup, Space Syntax, Davis Langdon

- Martha Schwartz Partners and Buro Happold with Squint/Opera, Davis Langdon, Quatro

- Stanton Williams

Ian Fry, programme director for Network Rail said: ‘The new square will become a key feature of the redeveloped station when it is complete in 2013.’
