This is not a huge white airship but the roof to this year’s summer pavilion for the Serpentine gallery in Kensington Gardens, west London.
Designed by Dutch architect Rem Koolhaas and structural engineer and Cecil Balmond, Arup vice-chairman, the airship roof has a practical, if unorthodox, function. It is partly filled with helium so it can rise up while remaining tethered to the circular enclosure made from translucent polycarbonate sheeting. Construction of the £750, 000 structure was managed by Bovis Lend Lease. The QS was Davis Langdon.
