The revitalisation of a 1980’s Sydney merchant house at 333 Kent Street has transformed this site into a state-of-the-art workplace designed for 2024 and beyond.

This $400 million office tower redevelopment project seamlessly merges past and future, maintaining the integrity of the original superstructure – a nine- level building with a ground and mezzanine level, while implementing significant internal and external alterations – including seven additional storeys and a new commercial façade while retaining the heritage façade.

BG&E provided comprehensive material testing, construction engineering, and structural engineering services from concept to completion.

Our work involved in-situ testing and investigation and analysis of the existing building’s concrete properties to preserve the original structural elements. A key challenge was strengthening the structure to meet the latest design code, and we ensured compliance through preparing performance solutions.

The project emphasised adaptive reuse and sustainability, delivering a carbon-efficient design solution while upcycling the iconic existing structure into an A Grade commercial building in the heart of Sydney’s CBD.
