This part of the precinct building has been demolished to make an access way from the original area to the car park over the service road. It is predominantly paved in the same walkway tiles, has several additional walls, seats, a grassy square and ornate stone bollards. 

Several other similar features, including sculpted seating areas, have been added to the existing area. 

If this note persists, once I've worked out what I'm doing, I will correct this :)
