90 Collins Street
Drawing on the character of its address, the proposed revitalisation of 90 Collins Street will deliver A-grade office space and a new skyline expression to Melbourne’s CBD.
Repositioning the underutilised asset will be achieved through a tripartite design approach with interventions to the ground plane, tower structure and lift core.
At ground level, the podium will be reconstructed to create a new laneway, lobby and entry experience, increasing functionality, permeability and activation. The lobby will feature grand proportions with inviting lounge areas for meeting and working.
Building upon the robust edifice of the existing building, the proposed tower design is a confident statement juxtaposing classic and new, solidity and lightness. The building’s facade will be refined and streamlined to increase transparency, activation and laneway connectivity. To the west, upgrades to the Collins Street frontage will feature a modern adaptation to the heritage facade.
Set atop the 22-storey office building, 16 storeys of new commercial space will provide additional flexible and sustainable floor space.
The new structure is a simple extrusion from the tower below. Its design is a powerful geometric form is expressed simply through elegant glass and elevated through functional and considered details.
A recessed landscaped area with living green will act as a visual buffer to delineate the new and old buildings.
An external lift shaft to the proposed tower addition is positioned on the northern side of the building, with glass observation elevators offering views of the city and the Yarra River. This new lift core will also add to the vibrant quality and dynamics of the ground floor lobby.
At street level, the pedestrian experience will be improved through the proposed intermittent vehicular traffic closure of a section of Pink Alley from Little Collins Street. ‘Greenification’ of the lobby and laneway using planted trees will enliven the sides of the building and create a memorable new laneway experience and visual link through to the new retail, food and beverage offerings.
