Californian-based architect Frank Gehry won the commission last year
Two-award winning Japanese architects have been commissioned to design the new summer pavilion at the Serpentine Gallery in London's Hyde Park.
The gallery has been commissioning a new pavilion every year since 2000 to host talks and events.
This year's structure will be built by Kazuyo Sejima and Ryue Nishizawa.
Their work is known for its blend of visual simplicity and technical complexity. The pavilion is expected to open in July.
The pair have created several high profile buildings worldwide - including the New Museum of Contemporary Art in New York.
Julia Peyton-Jones, the director of the Serpentine said: "It is our dream come true to be working with world-leading architects Kazuyo Sejima and Ryue Nishizawa."
Last year, the legendary California-based architect Frank Gehry used huge timber planks and glass panels to create a complex canopied pavilion for the Serpentine.
The pavilion series is the only commission of its kind worldwide which annually gives leading architects their debut in the UK.
