Rotor - Visitor pavilion

The visitor pavilion for Bruegel's Eye is discreetly integrated into its surroundings. Rotor uses a massive piece of Thuja hedge 25m long, 3m wide and 4m high as a facade, and pierces through it: the entrance to the pavilion. The conservatory is largely made up of materials from renovations. The pavilion is rather simple, but still also surprising. Are there people walking on top of the hedge?
