Rialto Towers, Melbourne

The Grollo family is possibly best known for building and owning Melbourne's iconic Rialto Towers.

Grollo Australia recognized the potential of the site on the corner of King and Collins streets when they acquired a 12 month option in the early 1980s as well as interest in the adjacent Winfield and Rialto buildings. In 1981, Grollo Australia entered into a joint venture with St Martin's Properties, a London-based company with significant commercial property ownership worldwide, to develop the site on the corner of Collins and King Streets.

In October 1982, Grollo Australia began construction and four years later, in October 1986, the 253 m high Rialto Towers opened.

The Rialto is a major Melbourne landmark. It is a world class tourist and business venue that incorporates excellent office facilities, an observation deck on the 55th floor, fine dining restaurants, cafes, theatre, function and retail facilities. The complex also includes a five star hotel created through the restoration of two historic buildings.

Designed by architects Gerard de Preu and Partner and Perrott Lyon Mathieson, the Rialto Towers is one of the tallest reinforced concrete structures in the Southern Hemisphere. Described as a masterpiece of light and space the towers are well known for their unique design and glass facade. Constructed of reinforced concrete, the two Towers, one 56 storeys and the other 43, are linked to become one.

Rialto Towers stand on 75 huge concrete legs attached to rock 20 m below the building and comprises a total area of 160,000 sq metres.
