London’s Serpentine Galleries has released the designs for its 2016 temporary summer pavilion and other new commissions it introduced this year – four summer houses.

Designed by Danish architect Bjarke Ingels Group (BIG), the 2016 Serpentine pavilion explores a concept of binary opposites.

BIG has conceived its pavilion design as an “unzipped wall,” which will be made from a series of extruded fibreglass frames stacked in a brick-like pattern. The wall will appear to split from itself, or unzip, as it descends towards the ground, creating a cavity in between to host the Serpentine Galleries’ program of events – a cafe by day and free performances by night.

From one angle the wall will appear as a transparent rectangle that allows views through its open frames. From the oblique view, it will appear to be a more solid, sculptural form.

“This simple manipulation of the archetypal space-defining garden wall creates a presence in the park that changes as you move around it and as you move through it,” Bjarke Ingels said.

“As a result, presence becomes absence, orthogonal becomes curvilinear, structure becomes gesture, and box becomes blob.”

“Bjarke Ingels has responded to the brief for a multi-purpose pavilion with a supremely elegant structure that is both curvaceous wall and soaring spire,” said a press statement issued by Julia Peyton-Jones and Hans Ulrich Obrist, director and co-director of Serpentine Galleries.

The four summer houses are each required to take inspiration from Queen Caroline’s Temple designed by William Kent and built in 1734, which is located in the Kensington Gardens near the pavilion.

Nigerian architect Kunlé Adeyemi will create an inverse replica of the temple, which he says will be “a tribute to its robust form, space and material, recomposed into a bold new sculptural object.”

American-German practice Barlow Leibinger’s design consists of a “summer house in the round” inspired by a now-demolished pavilion designed by William Kent that was located on a now-demolished artificial mound in the gardens.

French architect Yona Friedman reinterprets an earlier project of his to create a “space-chain structure” that can be assembled and disassembled in different forms and compositions.

London-based architect Asif Khan’s design attempts to reinstate a “lost moment” intended by William Kent almost 300 years ago.

“Through sun path analysis, I realized that Kent aligned the temple toward the direction of the rising sun on 1 March 1683, Queen Caroline’s birthday,” said Asif Khan. “We can imagine the Serpentine lake itself may have been designed to amplify this annual moment, a landscape-sized mirror to reflect the sun.” Khan speculates that the Serpentine Bridge, built by John Rennie in 1826, which traverses the lake, may obscure this effect.

“In our summer house, a polished metal platform and roof provide an intimate experience of the this lost moment for the visitor.”

The 2016 Serpentine Pavilion and summer houses will be exhibited from 10 June to 9 October.
