Bjarke Ingels' firm BIG has unveiled its design for this year's Serpentine Gallery Pavilion in London, UK. The Danish architect's design was imagined as solid wall that has been "unzipped" to create a three-dimensional space. It features a tall pointed structure made of interlocking fibreglass "bricks". It will be made from a series of box-like fibreglass frames stacked on top of each other, in a pattern based on a common brick wall. The wall of fibreglass blocks splits to create a curved opening to the pavilion with jagged edges.
