The Serpentine Architecture Programme expands for 2016, with four Summer Houses joining the Serpentine Pavilion. The Serpentine Pavilion, designed by Bjarke Ingels Group (BIG), is an 'unzipped wall' that is transformed from straight line to three-dimensional space, creating a dramatic structure that by day houses a café and free family activities and by night becomes a space for the Serpentine's acclaimed Park Nights programme of performative works by artists, writers and musicians. Kunlé Adeyemi's Summer House is an inverse replica of Queen Caroline's Temple - a tribute to its robust form, space and material, recomposed into a new sculptural object. Barkow Leibinger were inspired by another, now extinct, 18th Century pavilion also designed by William Kent, which rotated and offered 360 degree views of the Park. Yona Friedman's Summer House takes the form of a modular structure that can be assembled and disassembled in different formations and builds upon the architect's pioneering project La Ville Spatiale (Spatial City) begun in the late 1950s. Asif Khan's design is inspired by the fact that Queen Caroline's Temple was positioned in a way that would allow it to catch the sunlight from The Serpentine lake.
