Multiplex tops out at 80 Collins

9 August 2019

Builder Multiplex has topped out the new office tower at Dexus’ recently acquired site at 80 Collins Street in Melbourne.

The milestone heralds the next stage of the 41-level, 43,000sq m premium office building’s development.

Local architects, Woods Bagot have undertaken the design of the building base in collaboration with Dutch firm, UNStudio on the South Tower and hotel facades.

Office landlord Dexus acquired the site in May from the Queensland government’s investment arm, QIC, for $1.476 billion. Backed by a range of capital partners, Dexus pushed past rivals Charter Hall and Mirvac to purchase the mixed-use development.

Not only was it the largest sale in the commercial space for some time, it also increased Dexus’ share of managed office space in east of Melbourne’s CBD to about 20 per cent.

Despite the QIC’s investment in the site, it will see the development project through to its expected completion next year.

The South Tower will be complemented by a refurbishment of the neighbouring 47-level North Tower and the construction of a 255-room boutique hotel.

The new South Tower has a 6-star Green Star design rating and is targeting a 5 star NABERS Energy rating. The building is also WELL ready to allow customers to pursue further fitout certification.

80 Collins Street has used innovative construction methods such as the introduction of a double-deck lifting system with a destination control system.

All three towers will be linked by a 5000sq m retail precinct that will connect three neighbouring streets.

Featuring a faceted glass exterior and an interior design that will include flexible floor plates with the ability to interconnect floors, Multiplex regional managing director, Graham Cottam, said the build has been a technical challenge.

“80 Collins is also one of the most complex builds we are currently delivering in Melbourne, with the new South Tower constructed to cantilever 12 metres over existing buildings on Collins Street — the first time the engineering feat has been achieved to this scale,” Mr Cottam said.
