A Legacy of Distinction

Nestled on land once owned by Miami Beach pioneer John Collins, 3900 Alton stands at the crossroads of history and modernity. The site’s storied past traces back to the 1920s, when it flourished as a glamorous winter retreat before evolving alongside Miami Beach’s golden era. Once graced by lavish estates, the property lies just south of Carl Fisher’s iconic Nautilus Hotel—now home to Mt. Sinai Medical Center.

In the post-war boom, legendary architects like Morris Lapidus reshaped the landscape with modernist masterpieces such as the Saxony, Eden Roc, and Shore Club. Today, Ricardo Bofill reimagines this legacy with a bold yet timeless vision, transforming 3900 Alton into a residential landmark that honors the area’s illustrious heritage while setting a new standard for luxury living.
