The Rocks, Sydney
The refurbishment of this prominent heritage structure encountered complex challenges demanding expert heritage engineering.
Our primary focus was the overriding concern for the conservation of an existing State Heritage Register listed building. This involved input and design considerations from many stakeholders, design and heritage professionals and builders. Collaboration and constant communication is key to the ongoing success of this project.
The existing structure comprised 11 bays of historical materials, components and conditions. The site’s transformation includes a new dining precinct on the promenade side, with steel portal, architectural precast and glass awning.
An additional ‘Bay 12’ at the northern end features a new masonry structure, with similar, smaller awning. Bulk excavation works were limited to minimise risk to the structure. Demolition and strip-out works were tightly monitored. Issues uncovered included: cracked sandstone footings, damaged timber columns, and decay due to water ingress and rising damp. New materials sourced replicated the existing building type, quality and fabric.
TTW heritage specialists have overcome engineering challenges: heritage restoration works to sandstone and timber members, tidal water issues, and archaeological finds. Remains of an 1830s warehouse were discovered which altered the design to accommodate a new public viewing area.
