3900 Alton Residences Miami Beach



Rising gracefully amid the turquoise waters of Biscayne Bay, 3900 Alton brings the modern design of internationally acclaimed master architect Ricardo Bofill to the historic heart of Miami Beach, offering a residential enclave of luxury, convenience, and breathtaking views. Developer Mast Capital has assembled a visionary team of designers, artists, and craftsmen to create a lifestyle of quiet elegance and stunning beauty in an unrivaled location.
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.

3900 Alton joins a number of new luxury developments elevating the historic heart of Mid-Beach, which is recognized for its quiet elegance, natural beauty and relaxed ambiance. A luxurious oasis that affords residents and visitors access to golfing, yachting and a variety of water sports, all just
steps from the ocean, Mid-Beach also offers proximity to Miami’s finest shopping and cultural institutions.

From high-end retail to art galleries and worldrenowned dining hotspots, amid some of the finest architecture in Miami, the area attracts audiences from every corner of the world. This cosmopolitan convergence is the foundation of the neighborhood’s cultural scene that is distinguished within Miami.


A lifestyle of true sophistication is born through the vision of master architect Ricardo Bofill, founder of Ricardo Bofill Taller de Arquitectura, a Barcelona-based architecture firm. Setting new standards in simplicity, functionality and luxury, his designs have left a regal footprint around the world.
Noted for his signature design philosophy that embraces the “genius loci,” or the “spirit of the place”, Bofill produces a modern botanical refuge of 78 private residences at 3900 Alton, encompassed by a stunning glass façade, reflecting Mid-Beach’s distinct feel and its proximity to the ocean and Biscayne Bay.
