Designed by Icelandic artist Ólafur Elíasson with architect Kjetil Thorsen from Norwegian practice Snøhetta, the temporary pavilion in Kensington Gardens, London, will feature a two-storey winding ramp (see below for a link to Westminster's planning paper).
The building will be surrounded by a reflecting pool and is to be lit by daylight through an oculus in the roof.
Part art installation, part café - the central ground-floor space will seat 200 people - the scheme is a last-minute replacement for the unrealised pavilion by Frei Otto.
The 81-year-old German engineer's design was postponed earlier this month after it became clear that his 'pioneering structure' would need further development ( Otto off Serpentine, Balmond back in ).
Thorsen and Elíasson's pavilion was submitted for planning earlier this week - the second submission, after an incorrect fee was enclosed with the initial application.
Work is expected to start on site in May.
