Singapore-listed property developer and investment firm Tuan Sing Holdings has announced plans to reconstruct its mixed-use properties at 121-131 Collins Street and 23-25 George Parade in Melbourne.

Grand Hotel Group (GHG), a wholly-owned subsidiary of Tuan Sing, has instructed Hong Kong-based urban design firm Urbis Ltd to submit a Town Planning Application to the City of Melbourne for the proposed works.

The properties currently house the 550-room Grand Hyatt Hotel and various retail spaces.

Much of the existing podium structure will be retained in the reconstruction, allowing business operations for tenants and the Grand Hyatt Hotel to continue as usual.

The works will focus on façade modifications, extensive refurbishment, and reconfiguration of spaces in the property’s podium from levels 4 to 9B, according to Tuan Sing's announcement on Nov 14.

Upon completion, and subject to regulatory approvals, the site will encompass about 909,550 sq ft in total gross floor area (GFA) and introduce a new luxury retail and F&B precinct.

“The podium redevelopment at 123 Collins Street will redefine connectedness and activation at one of the most prominent intersections in Melbourne’s storied Paris End,” says William Liem, CEO of Tuan Sing.

He adds, "With the right approach, this transformation can be an architectural statement of our environmental stewardship. By reimagining rather than rebuilding, we’re pursuing an inherently sustainable vision that supports a thriving, connected, and culturally vibrant Melbourne for generations to come.”
