On Thursday evening, more than 150 guests filled the lobby of coveted Melbourne office tower, 120 Collins Street (“the Building”) to celebrate its 25th anniversary, at an event hosted by Investa.

Guests, VIPs and an array of property identities came together to share their connection to the 120 Collins Street history.

The lively event was a buzz of anecdotes celebrating the building’s history, the timeless architecture and the evolution of a landmark tower.

25 years ago, in August 1991, the Premium-Grade office tower was opened, taking the official mantle as Australia’s tallest office tower, at an impressive height of 265 metres.

Daryl Jackson, one of the original architects, was a guest and speaker at the event.  He said: “It is 25 years since I designed the 120 Collins Street tower, in association with HASSELL Architects.  Importantly, the tower allows Collins Street to remain intact yet also enables the development to fulfil its economic requirements.

Its architectural form that is broken down in scale at street level with a base or plinth out of which the middle and top rise, integrates the building with the Classic Queen Anne style Professional Chambers Building (now a Paul Smith shop) and with the neighbouring scale of St Michaels Uniting Church. These were key design criteria that have stood the test of time,” he said.

Jonathan Callaghan, CEO Investa also spoke at the event.  He said: “Investa’s involvement in the 120 Collins Street story started in September 2003, when we acquired the building as part of the takeover of the Principal Office Fund (BT Office Fund).  We were thrilled to acquire an asset that was both a Melbourne icon and a true reflection of contemporary office architecture that has become a flagship asset in our portfolio.”

Located at the desirable ‘Paris-end’ of Collins Street, the building is an iconic, premium-grade office tower with unsurpassed services and amenities.

Spanning more than 50 levels, the building has a Net Lettable Area of more than 64,000 square metres, which includes a four-storey foyer with surrounding café and retail offering.

Along with its timeless design and domination of the city skyline, what truly sets 120 Collins apart is the first class customer service that the onsite management team delivers. Tenants and guests are greeted by the concierge and have access to the @120 Collins tenant portal, creating an innovative digital community and providing time-saving services.

The building also has first class club-style change facilities in the basement, incorporating showers, bike racks, lockers and ironing facilities.

Co-owned by Investa Commercial Property Fund and Leader Auta Trust managed by Mirvac, the building is over 99% leased and continues to accommodate prominent global corporations such as Rio Tinto, Standard and Poors, Blue Scope Steel and Merrill Lynch.

Notwithstanding the significant development of the Melbourne CBD and Docklands precincts over the last two decades, 120 Collins continues to be a building in demand by office tenants.

Since July 2014, over 32,000 square metres of space have been leased and the building celebrates this milestone with only 376 square metres of vacancy, which equates to less than 0.6% of the building’s area.

The building has also undergone a multi-million dollar upgrade of key services and a face lift to the façade, seeing it well placed to service the new generation of occupants.
