100 Mount Street delivers a new landmark building for North Sydney

Dexus has achieved significant leasing at 100 Mount Street (100 Mount) which has resulted in near full occupancy, marking the delivery and completion of the premium tower to the North Sydney office market.

A total of 12 new customers have been secured across 40,110 square metres at 100 Mount. This takes leased space to 95%1 as the building reached practical completion, with the last vacant floor under negotiation.

Signed agreements have been reached with NBN Co, Laing O’Rourke, Victory Offices, First Data Resources, Chanel, NextGen.Net and Glorietta Restaurant and Café.

Dexus Head of Office Leasing, Chris Hynes said: “After years of limited supply, 100 Mount kicks off the next wave of quality office accommodation coming online in North Sydney that is appealing to a more diverse range of tenants who see North Sydney as a viable alternative to the Sydney CBD.”

100 Mount is a new 35-level premium office tower spanning approximately 41,500 square metres. The building occupies one of the best locations in North Sydney on the corner of Mount and Walker Streets, with a third street frontage to Spring Street. The site has prime retail exposure, excellent natural light, harbour views across to the Sydney CBD and is set to benefit from its proximity to the new North Sydney Metro Station currently under construction.

The development is targeting a 5 star Green Star and 5 star NABERS Energy rating, as well as a Shell & Core WELL Gold rating.

100 Mount is owned by Dexus and Dexus Wholesale Property Fund. The building was developed by Dexus in collaboration with builder, Laing O’Rourke.
