The regeneration of Melbourne’s iconic Rialto defines a new urban presence for the existing tower and its plaza within the surrounding historical precinct, referencing and incorporating the rich heritage of its neighbouring buildings. Designed by Woods Bagot, the rejuvenation creates continuity along Collins Street and adds 6,000 sqm of new office, retail, food and beverage space to the popular landmark. The site’s redevelopment spearheads a new generation of mixed-use space in Melbourne’s premier business hub.

高度为253米的丽奥图大厦于1986年营业，是当时南半球最高的办公大楼，最初为丽奥图公司、Grollo Group和St Martins Properties共同拥有，自1981年起，丽奥图公司成为唯一的所有者。Woods Bagot的首席建筑师Peter Miglis表示，尽管人们一直能够从远处眺望到丽奥图大厦的身姿，但其在街道层的样貌仍旧需要被重新定义，以建立更稳固的城市地位。
▼标志性的丽奥图大厦，the iconic Rialto Tower
Rialto opened in 1986 and when launched was the tallest office building in the Southern Hemisphere, standing at 253 meters. Owned by Rialto Joint Venture, Grollo Group and St Martins Properties, RJV has been the sole owners of the precinct since 1981. Woods Bagot Principal Peter Miglis said that while Rialto always had an identity at a distance, its presence on the ground needed redefining to confirm Rialto as a Melbourne city precinct.

“Previously the entrance of Rialto was set way back from Collins Street. Although Rialto is a commercial building, the ground space is civic and our idea was to create a public interface by extending the workplace for Rialto’s commercial tenants into a social networking precinct in the forecourt, and inviting visitors to enter and experience the space” says Miglis.
▼新的带顶路径连接街道与新建的广场空间，a new access for the public to move easily from Collins Street into a new plaza space
Woods Bagot’s design approach was two-fold: to create a visually coherent and active urban frontage to Collins and Kings Streets, while providing access for the public to move easily from Collins Street into a new plaza space. Rialto’s original large podium, while symbolic of 1980s architectural norms, was a dominating structure that offered no invitation to pedestrians to enter and engage with the building. Removing the podium allowed the formal architectural regeneration strategy to be implemented in three components: new commercial lobbies; a public plaza forecourt; and low-scale podium buildings to Collins and King Streets.

The sheltered landscape plaza between the lobby and new podium buildings provides flexible public space, activated by retail tenancies and serving as the forecourt entry to the lobby towers. Covered with a sculptural, self-supporting grid-shell structure, its triangular tessellated geometry mediates between the rotated axis of the towers and the podium buildings that conform to the city grid. The granite used in the lobby was hand cut in Canberra, reflecting the architects’ dedication to using local products throughout.

Two new, low-scale podium buildings now define the streetscape to Collins and King Street, complementing the size and form of the adjacent heritage buildings. They provide an additional 6,000 sqm of flexible workspace to the existing 84,000 sqm of office space and strengthen connectivity with linkages back to the existing tower. The architectural expression of the podium unites and takes cues from the existing blue glass towers and the adjacent grain of heritage buildings. The blue in the new podium is achieved through a stainless steel coloured mesh interlay that is embedded in the glazing unit.

In building on the retail culture west of the city’s central business district, the public interface that integrates Rialto’s corporate tenants and consumers cements Rialto as a destination and transforms Melbourne’s mid-town.
