One Sydney Harbour

Designed by renowned architect Renzo Piano, One Sydney Harbour is a landmark residential development located in Barangaroo, Sydney.

Commencing construction in 2019, when the three tower project was completed in December 2024, it brought a prestigious project to the Bangaroo locality, offering a total of 808 luxury apartments across three towers with heights of 247 metres (72 levels), 230m (68 levels), and 104m (29 levels). 

As part of the larger urban renewal precinct of Barangaroo, One Sydney Harbour is positioned as “a testament to modern architectural excellence and urban revitalisation,” a Horiso spokesperson says. “From its inception, the development aimed to set new standards in residential living, incorporating cutting-edge design and sustainable building practices.” 

One of the project’s most notable features is its open cavity façade, the first of its kind in Australia. This is where most of the specialised custom made window shading solution needed to be fitted. Prototyping of the blind system and fabrics started in 2018 and the product was subjected to quality testing including hot box testing, which consisted of operating the system in extremely high temperatures. 

A wind tunnel test was specifically designed for the project to ensure the tensioned blind systems would be able to operate under the high wind loads they would experience in an open cavity façade. The test included putting the blinds under high winds from a wide range of angles to ensure they performed ideally within the requirements of the building.

The blind installations commenced towards the end of 2020 and were finished for all three towers in December 2024.

“The custom developed metallised performance fabric CR88, from the Climate Ready Fabrics range, is a sustainable material specifically designed for tensioned shading systems. This fabric was chosen due to its high reflectivity, performance, high tensile strength and its excellent view through properties, which make it suitable for external applications. It not only provides effective solar control but also aligns with the project’s sustainability goals.

“The bespoke tensioned shading system, which was developed in conjunction with our partners in Guthrie Douglas, needed to be engineered to fit seamlessly into the tight façade spaces. The system designed was based on the design of the TESS 600 systems, which Horiso currently manufactures and exclusively distributes within Australia.”

Contracted to develop & deliver this complex shading solution in conjunction with Guthrie Douglas, our UK partners, and Climate Ready Engineering, Horiso manufactured over 7,500 bespoke tensioned shading systems for the project. 

“The project was successfully completed, with all three towers equipped with the advanced shading systems, which met the highest standards of functionality, durability, and aesthetic integration required for such a prestigious development.”

The One Sydney Harbour project exemplifies the successful integration of innovative design, sustainable materials, and advanced engineering solutions for window furnishing products, the spokesperson says. 

“The bespoke shading systems provided by Horiso played a crucial role in achieving the project’s vision of luxury living combined with environmentally sustainable responsibility.”

Horiso is an Australian manufacturer and supplier of custom solar control shading systems, including specialty external and internal venetian blinds, Sunshield rack arm louvre systems, Guthrie Douglas tensioned shading systems, and Forest Drapery tracking systems, all available with manual, motorised, and home automated control solutions.
