The project entailed extensive alterations and additions to an existing building to create a new Heritage Centre and Archives for the Sisters of Charity in Potts Point. Designed to showcase the Sisters' work since arriving in Australia from Ireland in 1838, the three-storey structure also features a repository for religious relics, lift, boardroom, staff offices and kitchen. The site works included major structural demolition, reinforced concrete structure, brickwork to match existing, new services throughout and a glazed link to the adjoining St Vincent's College school. Belmadar successfully navigated the following challenges: With an extremely tight footprint, the site had no space for materials storage and limited street access, impacting truck delivery capability. Following the demolition of half of the existing building, the remaining half had to be stabilised and secured. At the same time, new services were installed to meet the specific temperature and humidity requirements for the storage of religious relics.
