100 Mount Street was designed by Skidmore, Owings & Merrill with Architectus as architect of record, developed by Dexus with Laing O'Rourke as builder, and reached practical completion in May 2019. At 35 levels it is the tallest commercial tower in North Sydney.
It carries about 42,000 square metres over those 35 levels, with floorplates up to 1,300 square metres, and was designed to target a 5 star NABERS Energy rating and 5 Star Green Star Design & As Built. Dexus signed 12 new customers during construction, among them NBN Co, and the tower was 96 per cent leased at practical completion.
The address sits a short walk from both North Sydney Station and the Victoria Cross Metro entrance on Miller Street, which is what a North Sydney tenant is actually buying: this is a market that arrives by train, and parking is scarce enough that walking minutes matter more than car spaces.
