500 Bourke Street Melbourne
5 Star Green Star Rating
Project Overview500 Bourke Street, Melbourne, the global headquarters of the National Australia Bank (NAB) is a leading example of a high rise CBD sustainable office refurbishment. ISPT focused on delivering a design to nab which incorporated their particular requirements within 500 Bourke Street and is a leading example of landlord and tenant partnership.The property's unique architectural style, with exposed structural features, marks it one of the iconic land mark buildings in Melbourne. Refurbishment works include all base building services to each office level and the fitout across the 44,000 square meters of office accommodation. The refurbishment project commenced in December 2007 and will take two years to complete. Sustainability merit will be achieved through a number of key elements including the upgrading of services and finishes, redevelopment of the ground floor foyer and rear retail plaza to maximise the advantage of the Little Bourke Street frontage. The refurbishment has also provided an opportunity to reinvigorate the 1,260 square metre retail precinct at the property which will be known as The Court at 500 Bourke Street. Sustainability objectives include improving energy and water efficiency, indoor environment quality and resource efficiency over the life of the building. Bovis Lend Lease is project managing the design and construction, John Wardle Architects the ground plane architecture and Peddle Thorp Interior Design the office tower refurbishment. Constructed in 1978, NAB has fully occupied 500 Bourke Street since it was completed and in July this year signed a new 12 year lease to maintain the 47,000 square metre building as its global headquarters. |
