Gateway Locale

OneFourFive enjoys a rare city-edge position, close enough to the heart of the action but in a cosier neighbourhood without the imposing skyscrapers. Its enviable location also places OneFourFive between South Melbourne, Southbank, Port Melbourne and the Royal Botanic Gardens, so employees can spend time away from the office shopping, dining or relaxing outdoors.
