Concept aimed to replicate Frost Fairs

Architecture practice NBBJ has released concept images of retractable ice rinks which could be dotted along the river Thames in London.

The idea proposes jetties that would unfurl into large circular discs. Submerged slightly below the water level, these pan-like objects would isolate a thin basin of water from the flow of the river which NBBJ said would enable the water to naturally freeze.

The practice said the move bring back to the capital so-called Frost Fairs – public ice-skating, markets and exhibitions – which were held on those parts of the Thames that had frozen over in winter.

NBBJ said the initiative was an idea only but could be adapted for a number of locations in London as well as other cities around the world.
