This project marks the first private residence in Australia to be developed in collaboration with the global design house Armani/Casa. The sub-penthouse project presents a single-floor residence that occupies level 53 of the development and represents a significant milestone for the country's luxury real estate market. The property's interior palette is drawn from the signature 'greige' tonal register coined by [Giorgio Armani](https://www.trendhunter.com/trends/Admiral-Yacht). This luxury-forward sensibility is layered with materials including sand, off-white, Canaletto Walnut, and Satin Light Brass. Every finish and fixture is handmade in Italy by artisans using traditional techniques, including exclusive hand-applied treatments such as Brass Carved Liquid Metal and White Gold Drafted Stucco. At its core, the Cove offers an unprecedented opportunity to inhabit a space that is not merely a residence but a complete immersion in the Armani/Casa philosophy.
