The 1.2 acre site in Canterbury was formerly the Nunnery Fields Hospital. The development comprises 21 new houses and 37 apartments. The existing Infirmary, Chapel and ‘Workhouse’ buildings are ‘locally listed’ and were retained and refurbished as part of the development.
After extensive investigations, Manhire Associates developed structural proposals retaining the existing facades with new internal cross wall construction in load bearing masonry for the ‘Workhouse’. The existing foundations were carefully assessed to ensure that settlements were limited. The brickwork was bonded with lime mortar and the durability of the retained construction and the effects of moisture ingress were considered. Existing Victorian cast iron wall ties were found to be have corroded leaving large panels of masonry unstable.
Details were developed that were sympathetic to the buildings, giving appropriate thermal performance and protection against moisture ingress. The joints were carefully detailed, and the works inspected in conjunction with the NHBC.
