Keystones pioneering brick slip system ensured quality control standards were maintained throughout the manufacturing process. A consignment of light textured Parham Red bricks were collected from site, which reduced brick wastage and improved material management. Double Cant bricks were precisely cut and bonded offsite onto an extra heavy duty corbelled arch lintel using a BBA approved construction adhesive in a factory-controlled environment. The one-piece lintel design solution required exacting dimensions to avoid any conflict with the proposed stone sitting at the end of each arch bearing. 3593mm upper and 3143mm lower coursing span measurements were essential for the seamless installation of the prominent entrance.

Integral key prefabricated lintel components were all manufactured concurrently as opposed to sequentially and offered greater predictability of operational expenditure during the build programme. Delays associated with bad weather onsite were avoided which allowed for high quality and consistency to be achieved when replicating the four large full arch lintel designs. The impressive 4300mm span and 2150mm rise arches were delivered to site ready for final pointing. All the arch lintels included lifting hooks for an easier and safer installation.
