Award-winning designers Speirs + Major, in association with King’s Cross Central Partnership, are to unveil HALFLIFE, in the 90-metre pedestrian tunnel that connects David Chipperfield’s One Pancras Square office building to the King’s Cross Underground network.
Opening on 6 March, HALFLIFE is inspired by British physicist Ernest Rutherford’s principal of decay, the concept being that visitors may witness the changing cycles of growth and deterioration through light and colour.
The tunnel’s glazed wall conceals 180 sources of light, which work together to create a rich palette of animated colour. Each of the sources has five unique hues of red, green and blue light that are complemented by warm and cool white, which will be carefully blended together to create a wide variety of tones and saturations. No one moment in the tunnel will be the same, which means each experience will be unique.
