The Serpentine Gallery in London has selected Chilean architect Smiljan Radic to design the 2014 temporary pavilion.
Radic is the fourteenth architect selected to design a temporary pavilion for the gallery.
Plans include a semi-translucent, cylindrical structure designed to resemble a shell, resting on large quarry stones and occupying a 350m² footprint on the gallery's lawn.
The Serpentine Gallery's Pavilion 2014, which will feature a café, will act as the venue for the Serpentine's annual Park Nights series of events.
The pavilion will allow visitors inside during its four month tenure and encourage them to interact with the space in different ways.
Radic called the design part of the history of small romantic constructions seen in parks or large gardens; the so-called follies, which were hugely popular from the end of the 16th century to the start of the 19th.
"Externally, the visitor will see a fragile shell suspended on large quarry stones," Radic said.
"This shell, white, translucent and made of fiberglass, will house an interior organised around an empty patio, from where the natural setting will appear lower, giving the sensation that the entire volume is floating."
Radic's design follows Japanese architect Sou Fujimoto's cloud-like structure, which received about 200,000 visitors in 2013.
Zaha Hadid designed the inaugural pavilion in 2000 and other previous commissions include Herzog & de Meuron, SANAA, Frank Gehry and Peter Zumthor.
AECOM will provide engineering and technical design services and also act as cost and project manager for the 2014 Pavilion.
The pavilion will open on 26 June and will remain in Kensington Gardens until 19 October.
