Big is the defining word of this year’s Serpentine Pavilion. It’s designed by BIG (Bjarke Ingels Group, the newest starchitects-on-the-block), and its aerial-like pointed roof soars to the sky. By taking a simple object – a fibreglass hollow “brick” – and repeatedly stacking it on a huge scale, Bjarke Ingels has made a structure that, from one angle, is a wall full of holes through which you can see the greenery of Kensington Gardens, framed multiple times over. Move around it, though, and the pavilion turns into what looks like the cross-section of a twisting iceberg.
