Proposed Gold Coast Residential High-Rise features 1:13 Slenderness Ratio

Gold Coast, Australia – 16 March 2017

Golden Gate Property has unveiled the architectural design for a AUD$200 million (USD$154 million), cutting edge residential tower on a prime beachfront site in Surfers Paradise. A development application for the tower was lodged with City of Gold Coast.

The 2-4 Wharf Road project elevates prestige apartment living, offering 35 one-per-floor luxury sky residences, a two-story sub-penthouse, three-story penthouse, 450-square-meter stand-alone beach house, and a residents-only wellness facility and spa.

Using the latest advances in parametric design tools, wind engineering, and modeling technology, the project is designed to rise 44 stories, 154 meters high by 12 meters wide, giving the project a tight slenderness ratio. At 1:13 it is on par with Phoenix in Melbourne; however, its slenderness pales in comparison to the likes of 111 West 57th in New York, which boasts a 1:23 ratio.

Design architect Rothe Lowman said they worked to revolutionize their architectural approach to designing the high-rise residential tower to balance the beauty of an absolute beachfront location with unique site proportions and prevailing winds.

The architectural design of the tower is an adapted diagrid exoskeleton, able to deal with the dynamic wind and structure loads while being suited to complex formal outcomes.

The structural elements of the architectural design respond to the exposed beachfront conditions of the site, which experiences low-turbulence wind flow off the ocean. The exoskeleton increases tower width by two meters and adds torsional stiffness while maintaining expansive ocean views. The tapered base reduces the building’s bulk and scale while also improving views for neighboring sites.

“Tethered to the earth and resisting forces, this is one of the few residential towers that derive its aesthetic from its structural expression,” Rothe Lowman Associate Principal Jonothan Cowle said. “This slender residential tower is a wonderful example of collaborative and creative innovation, the fusion of architecture and wind engineering to create a design that is uniquely crafted to its context.
