Here's a full set of images from this year's Serpentine Gallery Pavilion by Japanese architect Sou Fujimoto (+ slideshow).
Unveiled this morning, Sou Fujimoto's design features a cloud-shaped grid of steel poles with varying density.
The sticks part to form two doorways and visitors can climb up onto transparent ledges within the structure.
They can also sit at cafe tables and chairs underneath, sheltered from above by a layer of transparent plastic discs.
The pavilion will open to the public from Saturday and remain in front of the Serpentine Gallery in Kensington Gardens until 20 October 2013.
Dezeen published the first photos of the Serpentine Gallery Pavilion 2013 from the press preview this morning, where Fujimoto explained how he wanted to "create a nice mixture of nature and architecture," adding "that has been the great interest for me these last ten years."
See more architecture by Sou Fujimoto on Dezeen, including a house that looks like scaffolding and a library with shelves on the outside.
The annual unpaid Serpentine Gallery Pavilion commission is one of the highlights in world architecture and goes to a high-profile architect who has not yet built in the UK. At 41, Fujimoto is the youngest to have accepted the invitation.
Past commissions include Herzog & de Meuron and Ai Weiwei, Peter Zumthor, Jean Nouvel, SANAA and Frank Gehry.
