Each year, just in time for the sunny weather, the lawn in front of the Serpentine Gallery in London’s Hyde Park is transformed by a temporary pavilion designed by a well-known architect. Last year there was Sou Fujimoto’s ethereal climbing frame, the year before a dug-out cork pit by Herzog & de Meuron and Ai Weiwei, and other years saw pavilions by names such as Rem Koolhaas, Jean Nouvel and Zaha Hadid. This year’s iteration is by Chilean architect Smiljan Radic, it’s a curvaceous structure of fibreglass sitting atop a Stonehenge-like array of boulders. Inside it feels like a protective cocoon, with light coming through the translucent shell and cut-outs to the landscape beyond. It opens to the public on Thursday (26th June) and is usually one of the most popular art/architecture events in the city over the summer, there’s a cafe inside and people usually spill out onto the grass around.
