A Modern Gem in Historic Miami Beach

Located in the historic heart of Miami Beach, 3900 Alton is unrivaled in location as it is minutes away from Miami’s Design District, Faena District, and Sunset Harbor, not to mention some of the most exclusive restaurants in Miami. Mid-Beach is home to recent arrivals by the likes of Faena House, The Miami Edition, and The Ritz Carlton, among other swanky hotels and residences, making the area Miami Beach’s most desirable location while preserving the distinctive feel of a private oasis.

Internationally-hailed architect Ricardo Bofill is behind the brilliant construction that is 3900 Alton. A team of designers and artists assembled by Mast Capital envisioned a lifestyle of understated elegance and stunning beauty, and they executed to absolute perfection. Modern design and timeless elegance meets state-of-the-art technology with residential features like floor-to-ceiling energy-efficient windows for unbeatable views of beautiful Biscayne Bay, and a Savant automation system which is accessible directly from a smartphone. Additional smart features include TESLA house car and TESLA charging station. Outdoors a lush garden surrounds an expansive pool and spa complete with cabanas and lounging daybeds for ultimate relaxation.

3900 Alton’s Enviable Location

All of South Florida is at your fingertips. You’re just steps from casual eateries like Bagel Time Cafe, Beyond by Shemtov’s, and Montefiore Cafe & Restaurant, yet you’re also mere minutes from upscale dining experiences like Katsuya, Sardinia, and Yardbird Southern Table & Bar (which happens to be just steps from the famous Lincoln Road).

Take your pick from the endless nightlife options nearby. The Forge features a vast and nationally acclaimed wine cellar in what was once a blacksmith’s forge, Nikki Beach is a Miami Beach hotspot on the soft sandy shores, and Rec Room revives nostalgia for decades past with its ‘70s decor and intimate setting.

Living in 3900 Alton means you’re just steps from the prestigious Miami Beach Golf Club, Lincoln Road Mall, world-famous Ocean Drive, and the heart of Miami itself. In just 10 minutes, you can be lounging on the pearly white sands of South Beach, exploring the unique shops and restaurants sprinkled throughout Brickell, and marveling at artists’ masterpieces in Wynwood. And with 195 just a stone’s throw from this Miami Beach building, you’re never far from your favorite South Florida destinations.
