The building is proposed as a “sister” to International House Sydney, also designed by Tzannes, which was completed earlier in 2017.

The proposed building will be located at Hickson Road in front of the Rogers Stirk Harbour and Partners-designed International Towers Sydney.

Tzannes describes the collection of buildings as “three brothers and two sisters.”

The proposed building will be designed in a similar language to that of International House Sydney and will be constructed from cross-laminated timber and glulam.

“The proposal [will] provide a distinctive, yet integrated built form as the front door to the Barangaroo precinct,” said the architects in a design statement.

“The proposal is in two parts: a two storey base that includes the colonnade and responds to the scale of the public environment, and an upper five storey form as a clean simple glazed envelope that allows the interior timber elements to be visible from the outside and celebrated as the hero.”

Lendlease will target a six-star Green Star “design” and “as built” rating for the building.

The proposed building will be the developer’s sixth engineered timber building in Australia, following its Forte apartments, Library at the Dock by Clare Design and Hayball and a 52-metre tall office tower in Brisbane designed by Bates Smart, which, when complete, will be the tallest engineered timber building in Australia.

Rob Deck, managing director of Barangaroo South, said Australia’s first engineered timber office building, International House Sydney which was completed in 2017, “received an extraordinary amount of interest from a broad cross-section of the property industry, business sector and general public”.

Mr Deck said construction of CLT buildings is sustainable, as being timber it did not require drilling or concrete pouring, which made it a quiet building site with minimal wastage.
