It's a 16 year old summer tradition: every year London's Serpentine Gallery commissions a famous architect to design and build a summer pavilion in the park. It has to be an architect whose work has not yet been shown in London. This year is a special treat: one pavilion and four summer houses and all of them architectural gems.
The big one is by Bjarne Ingels Group (BIG) from Denmark. It has been described as an ‘unzipped wall’ by the architects. It is the selfie spot of the summer.
