Heritage Feature Project – The Abbey, Johnston Street, Annandale

The Abbey, is a historic home built c1882 by John Young, Sydney Mayor, master builder and engineer. The landmark building is a Stone Gothic Revival Mansion, modelled on a Scottish Manor. The home consists of the main residence of traditional stone masonry construction incorporating gables, arches, gargoyles, lions, quatrefoils, chimneys, turrets, a cloister and a tower with copper cladding. The rear coach house/stables have more experimental construction with open arched timber roofs and the claimed first use of reinforced concrete construction in Australia. The Abbey is listed on the local government register of the New South Wales Heritage Database and on the non-statutory register of the National Trust of Australia.

The buildings fell into disrepair before undergoing major conservation, restoration and adaptive re-use works from 2010 until 2015, when it received the RAIA National Architecture Award for Heritage and the NSW Greenway Award for Heritage Architecture.

Heritage Feature Project – Maritime Vessels, Australian National Maritime Museum

Partridge has carried out the structural design for various support structures and restoration works for the Maritime Museum’s heritage vessel assets. One project involves restoring and transporting a 18.5m long 1970s Vietnamese fishing boat named ‘Tu Do’ from Sydney Harbour onto a welded steel base, which will support and stabilise the boat structure during transportation into the Museum, and for its permanent exhibition within the building. A structural assessment was made of the vessel to determine appropriate support points to ensure the integrity of the vessel during transportation and beyond. Partridge has also designed a system of cables and steel beams to carefully support a heritage timber canoe from the roof structure of the maritime museum building, ensuring no permanent damage to the vessel.

Heritage Feature Project – Rouse Hill Woolshed

Following Rouse Hill Estate’s acquisition by the state government in 1978, the woolshed was stabilized. However, the ongoing deterioration of its simple timber-post footings left them at risk of collapsing. There is also damage from termites and borer which meant that a major intervention was needed to ensure its survival. The original timber framed structure was suffering from weathering deterioration, neglect and settlement was reinstated. Building features included post and beam timber structure all connected with ‘mortice and tenon’ joints, timber slab walls, timber plank floors on ground, and corrugated steel roof. Deteriorated structural elements were identified and areas of rot were replaced with new timbers spliced to existing. Additional bracing elements were only added where required.
