The Rialto project was not only a defining moment in Melbourne’s construction industry, it represented our stepping-out onto the world stage as capable of building massive projects. It also cemented a long and honoured relationship between the Williams and Grollo families.

Rialto Towers is the tallest reinforced concrete structure in the Southern hemisphere and is a stand-out attribute to Melbourne skyline. Rialto is a linked two tower development comprising 55 lettable floors in the South Tower and 40 in the North Tower. Five levels of underground car parking, an observation deck and rooftop communication centre.

Three main plantrooms provide heating and cooling to more than 100 air handling units, pushing air through 57 levels of office space and extracting car park exhaust from five levels below ground.

Since the building’s official opening in October 1986 it has retained a comparable status with other more recently completed landmark buildings. Rialto remains an Australian icon.
