Architects devise South Bank ice rink concept

The 'Frost Flowers' take the form of retractable jetties that would unfurl into large circular discs.

Submerged slightly below the water level, NBBJ claims that these these pan-like objects would isolate a thin basin of water from the flow of the river and enable the water to freeze naturally, providing a surface for skating and other activities.

"In a dense, modern city such as London the Thames provides a unique open vista where the history and origins of this great city can be viewed," said Christian Coop, design director of NBBJ.

"A draw for Londoners and tourists alike, the South Bank has become a bustling leisure area with bars and markets lining the river.

"New space is now desperately needed, and accordingly we looked to our heritage to find one possible solution."

The concept images produced by NBBJ show the 'Frost Flowers' on the South Bank close to County Hall, the London Eye and Jubilee Garden – although the firm claims the idea could easily be adapted to a wide range of locations.
