Per Speculum is a pavilion for people to gather at the Royal Docks in East London.
Inspired by the writings of Hermann Helmholtz, the pavilion creates an illusion whereby views into the structure are distorted inside an angular chamber. The ribbed walls are inspired by old fashioned camera bellows and the historical setting of the Royal Docks. The window at the rear of the folly acts as an aperture offering views to the old mill behind.
