David Pulley of ONE Sotheby's International Realty and Mick Duchon of The Corcoran Group have closed the sale of Beach House 200 at 321 Ocean Drive in Miami Beach for $9,900,000. The residence closed in September 2026.

Set directly on the sand in South of Fifth, Miami Beach's most coveted neighborhood, Beach House 200 is one of the signature residences of 321 Ocean, an intimate boutique building completed in 2015. The home offers direct ocean views and easy access to the shoreline just beyond the door, with the restaurants and calm of the southern tip of the island close by.

The residence is a duplex of about 3,745 square feet, and it was fully renovated with a clean, modern aesthetic. Expansive glass walls pour natural light across the interiors and frame the Atlantic, the palms and the dunes from the main living spaces. A marble-clad kitchen opens to a long dining area, and the living room and a separate family room both look out to the water. The two-level layout delivers the scale and privacy of a single-family home, with four bedrooms and four and a half baths, including a primary suite with ocean-facing glass and a marble bath.

It is the kind of residence that rarely comes to market in South of Fifth: a true beach house with the services and security of a boutique oceanfront building, set up equally well for entertaining and for slow, sun-filled days by the sea.

For Pulley and Duchon, it is a standout oceanfront close, a turnkey South of Fifth duplex where privacy, light and the rhythm of the ocean set the tone every day.
