Opportunities like this rarely come to market. Expect to be enamored as you step into this Gold Coast duplex penthouse topping a historic Astor Street art deco building. A collaboration between designer Michael Smith and architect Marvin Herman, the duo thoughtfully reworked the entire apartment creating harmonious spaces, rooms drenched in natural light, stunning finishes, a mindful floor plan and the finest of details throughout. Stepping off of the elevator, directly into the home, expect to be welcomed by a Venetian-plaster entrance hall with specially designed staircase and openings leading into three well placed living spaces; the main living, dining and family rooms.
