Harry Seidler’s iconic Sydney MLC Centre – once the world’s tallest concrete office building outside
North America – is set to undergo a major redevelopment that will see its
architect’s original designs advanced.
Co-owners of the building GPT and QIC have lodged a Development
Application (DA) for the proposed $150 million project, which will be designed
by Harry Seidler Associates and Woods Bagot. In keeping with Seidler’s public
space-focused designs, 80 per cent of the site’s footprint will be activated to
contribute to a vibrant and diverse CBD community,
visionary design that was at the core of Harry Seidler’s original building is
integral to the ongoing redevelopment. Seidler created a flexible and
sustainable destination where people could gather for both business and
pleasure, and this project is reviving and advancing his original vision for
the site,” says GPT Head of Investment Management for Office and
Logistics, David Burgess.
metres and 67 storeys above the CBD, the precast concrete structure was
designed to only occupy 20 per cent of its site, while a podium of plazas and
outdoor cafes planned on various levels open out onto surrounding streets – a
“city within a city”, as Seidler called it.
Centre is more than an office, it will connect people through a broader
experience. We are closing in on our vision to create a vibrant destination in
an unrivalled central location, with iconic retailers and great places to eat,
drink and socialize,” adds Burgess.
Plans include a new flagship luxury tenancy, laneway
activation, luxury retail tenancies along both King and Castlereagh Streets in
Sydney’s CBD, and an upgrade of the commercial tower’s lobby. A new restaurant and café precinct on Martin Place will also be created.
Covering 6,000sqm of retail and outdoor areas, the proposal will also look to deliver the following:
- Landscaping to the external plaza by providing open space
- Increased public seating available on the Plaza level
- Improved quality and design of fittings and furniture
- New and improved public amenities, including parents rooms
Already, refurbishment of the tower floors have been completed, with work
ongoing for the redevelopment of the MLC food court and end of trip tower
Completed in1977, the MLC Centre was constructed with a rigid load-bearing core of cross-walled concrete,
the weight of its exterior carried by eight heavily loaded columns that vary in
plan, shape and area from bottom to top. It was awarded the RAIA Civic Design
Award in 1981, and the Sir John Sulman Medal in 1983.
