The Penthouse/93 Kavanagh Street

Four Penthouse Residences. One Crown Above Melbourne. For over twelve months, OSK Property has worked in close collaboration with COX Architecture to design four singular residences at the pinnacle of Melbourne Square. Every line has been drawn with purpose. Every material, sourced from the world's finest selections. The result: The Penthouse Collection four one-of-a-kind residences that define a new chapter in Melbourne's skyline. Each residence spans two levels, defined by grand 6-metre volumes in the main living spaces and refined 3-metre ceiling heights across the more private quarters. Designed as four-bedroom, four-bathroom homes with study and two secure parking spaces, every penthouse features a sculptural fireplace and a private upper suite with panoramic views. Each residence bears a name drawn from the world's most enduring symbols of rarity The Amethyst, The Emerald, The Sapphire, and The Ruby. Like gemstones, each captures a unique orientation of light: a singular perspective, cut and composed for brilliance from every angle. The Amethyst297m²$7,728,000 Facing the city. Defined by symmetry and skyline. A residence of vertical clarity and calm. The Emerald316m²$8,538,000 Overlooking the Royal Botanic Gardens.
