Mercantile Mutual Extension Sydney

Mercantile Mutual extension

Many buildings have been extended horizontally while the existing structure remains occupied. A few buildings have been strengthened and extended vertically, but the existing building is usually vacated during construction. However, in this case, extensive construction works were undertaken to build an eight-storey vertical extension while the existing building below continued to provide a safe working environment for one thousand employees.

The brief was set by the institutional owner of the Mercantile Mutual Centre at 347 Kent Street, Sydney to the Project Manager, Construction Project Management (CPM) in November 1994. Simply put, it involved extending the existing 18-level commercial office block to achieve the maximum allowable office space under current building regulations while maintaining normal business activity in the existing building.
