Enhancing a magnificent piece of Sydney’s heritage


NSW Parliament House has been the seat of the state’s legislature since 1829 and is of exceptional social and historical significance to the people of New South Wales.

Together with the Mint building, NSW Parliament House is one of the oldest public buildings in Australia.

Woolacotts Consulting Engineers was engaged as structural consulting engineers for the addition of new corporate accommodation.

The parliament is committed to improving onsite accommodation for staff, and the project involved the removal of sheds and structures on the existing rooftop, the creation and fit-out of 600 square metres of office space on level nine, and new rooftop garden landscape works.

The Jubilee room features a magnificent intricate stained glass skylight which provides natural light to the room. As part of the project, more floor space will created above this historic skylight. To allow natural light to continue to flood the room below, Woolacotts designed new steel framing to support a glass floor. The engineering challenge was to build a new roof, before removing the existing lantern, to avoid damage to the heritage ceiling.

“Heritage projects require the smarts to design something new that won’t interfere with the old,” said Operations Director and Principal Engineer, Stephen Branch.

“This is a wonderful opportunity to enhance an historic and iconic piece of Sydney’s heritage,” he said.
