Per Speculum is a pavilion that forces perspective and distorts space, scale
and proportion. It has been designed to challenge the senses and encourage play and performance.
Inspired by the writings of Hermann Helmholtz, NKA create an illusion whereby perspective views are distorted inside an angular chamber. The ribbed walls are inspired by old fashioned camera bellows and the historical setting of the site. The window at the rear of the folly acts as an aperture offering views to the old mill over the docks behind.
OSB partitions were coated in a black wood-preserving water-based stain, giving the pavilion its dramatic colour. A red solar-shaded mesh was stretched between each of the trusses and pinned back with timber fascias. Each of the trusses were fixed down
to a reinforced concrete base using chemical anchors and stainless steel brackets.
To create the illusion, the sloping floor rises 300mm from the ground level to the back of the pavilion. The tiled floor covering required each to be a different size and diminish in area towards
the back of the structure. The tiles were cut in from artificial grass using a template and mounted on the floor deck using a rubberised floor adhesive.
The structure was in place for the duration of the London Festival of Architecture, forming a congregation space and shelter from the wind.
