Situated on land once owned by Miami Beach pioneer John Collins, 3900 Alton is located in an area with a rich and vibrant history. From its origins as a winter playground in the 1920s to its prominent location during the area’s boom years, the evolution of the site mirrors the growth and development of Miami Beach. Once dotted with luxury homes, the site of 3900 Alton sits directly south of legendary developer Carl Fisher’s grand Nautilus Hotel, which is now home to Mt. Sinai Medical Center. In the years following World War II, as the area’s population expanded, renowned architects like Morris Lapidus descended on Miami Beach, designing a collection of world-class resorts, including the Modernist Saxony, Eden Roc and Shore Club. A new timeless vision by master architect Ricardo Bofill will transform 3900 Alton into an exclusive residential destination while playing tribute to the area’s luxurious past.

Rising gracefully amid the turquoise waters of Biscayne Bay, 3900 Alton brings internationally-acclaimed master architect Ricardo Bofill’s U.S. condominium debut to the historic heart of Miami Beach, offering an enclave of luxury, convenience and sophisticated leisure for its 78 elegantly-appointed residences . Every detail and architectural component will complement the surrounding environment with spaces bathed in natural light, while Bofill’s transparent glass architecture will highlight Biscayne Bay’s transcendent views from dawn to dusk. Developer Mast Capital has assembled a visionary team of designers, artists and craftsmen to create the 8-story property, featuring art collections and integrations curated by ICart, as well as the work of notable artists Fernando Mastrangelo and Loris Cecchini throughout the property.
