Property Markets Group and S2 Development have pre-sold 60 percent of the Muse Sunny Isles condominium tower and begun demolition in preparation for groundbreaking. The project located at 17141 Collins Avenue will have 68 units ranging from two or three bedrooms to full-floor penthouses. Reservations for the ocean front tower were converted into pre-sale contracts in June 2014 while PMG secured a $126.8 million construction loan through Guggenheim Commercial Real Estate Finance this past December. The developer plans to include robotic parking, face recognition software in the elevators, and biometric safes in every unit.
