As the street was to remain fully open to all types of traffic, the design of the surface played an important role in directing movement. The plan size, blend of colours and use of white granite kerbs laid flush with the surface all played a part in suggesting particular routes through the space, while physical barriers, such as upstand kerbs, were removed. To aid the visually impaired through this unusual space, the designers included a strip of tactile paving that ran the full length of the street. The interface with the pavilion gardens took its cue from Nash’s original logic and a timber fence was established at the boundary. The fence curves in section to become an extruded bench, with its geometry derived from armchairs and their more relaxed approach to sitting. A range of surface finishes to the granite was chosen in response to particular need. The setts and slabs were finished with a flamed surface to provide adequate grip to pedestrians and vehicles. To the front of the long timber bench, a split-faced finish proved an effective deterrent to skateboarders. For the edges with adjoining streets, a heavy split-faced finish was used to generate a slight rumble strip that provides the motorist with a signal that they are entering a different type of space.
