High level wall to raised amenity level. Size approx. 9 ft high and 300 ft long. Architect: Hugh Martin & Partners. This was done in precast concrete using polystyrene moulds. The piercings in each panel were part of the design, at the request of the structural engineers, to reduce weight. The sharpness of the detail in this technique is remarkable considering the delicacy of the mould material. The original plain concrete has been overpainted in a neutral colour. The effect is not detrimental.
