Property Markets Group and S2 Development broke ground on Muse Residences in Sunny Isles Beach last week.

Muse, at 17141 Collins Avenue, will have 68 units when completed. Floor plans will range from two bedrooms to five, and start at 2,360 square feet. Muse will also include two full-floor penthouses with more than 5,800 square feet. It’s slated for completion in the fall of 2018, according to a press release.

Developers began converting reservations to contracts in July 2014. PMG and S2 closed on a $133.7 million construction loan for the 47-story residential tower in August. ISG World is the project’s exclusive sales and marketing firm.

New York-based PMG is also developing Echo Brickell, Echo Aventura and Sage Beach in Hollywood Beach. S2 is also behind O Residences in Bay Harbor Islands and Uptown Marina Lofts in Aventura.
