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.

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.
