Sotheby’s Concierge Auctions has revealed that the bidding for a stunning oceanfront estate, situated at the southernmost point of the U.S., has officially begun at $8.5 million. Originally listed at $18.5 million, this historic property in Key West once served as the winter residence of famous American artist John Seward Johnson II. The auction will take place in partnership with Ellen Gvili of Ocean Sotheby’s International Realty. The final live bidding will conclude on March 31 through the company’s online platform, conciergeauctions.com.
Situated at 400 South Street, this 4,008-square-foot concrete home rests on a 17,243-square-foot lot, complemented by nearly an acre of bay bottom and 245 feet of waterfront with breathtaking views of the Atlantic Ocean. The property features expansive balconies, a 50-by-20-foot pool, and ample lounge spaces, all surrounded by lush tropical landscaping. With approval from the U.S. Army Corps of Engineers to rebuild a private dock, this home is an ideal retreat for boating aficionados.
Inside, the formal living room captures the essence of classic Key West style, leading to a sunlit Florida room with floor-to-ceiling sliding glass doors that open directly to the outdoors. The primary suite, along with two guest bedrooms—accessed by an elevator—each open to a generous balcony offering uninterrupted ocean vistas. The home’s design is highlighted by sealed coral stone floors, sophisticated architectural elements, and an open-concept layout that enhances its timeless appeal.
This property also boasts a rich cultural heritage as the former residence of John Seward Johnson II, the grandson of Robert Wood Johnson I, co-founder of Johnson & Johnson, and the founder of New Jersey’s Grounds For Sculpture. Renowned for his life-sized trompe-l’œil bronze sculptures that depict everyday moments, Johnson’s works are displayed in public spaces globally, adding to the legacy of the home.
“This property is one of Key West’s most iconic estates,” said Gvili. “Its elegance is unmatched, from the sophisticated architectural details to the expansive oceanfront views. Situated at the southernmost point of the U.S. and once home to artist John Seward Johnson II, the house seamlessly blends timeless charm with history and luxury. It’s a rare opportunity—whether as a private sanctuary or a development opportunity, the estate offers great potential in one of the most coveted locations in the Keys.”
The estate combines opulent features with the added benefit of a transient license, making it an excellent opportunity for short-term rentals. Additionally, the property offers multifamily zoning, allowing for the development of up to eight residential units, further increasing its investment potential.
Situated in a prime location near the best of Key West, this property is only a short walk from the Southernmost Point buoy and Southernmost Beach, home to a well-known beachside eatery. Key West offers a perfect mix of historic charm and luxurious island living, with its iconic Conch-style homes, grand Victorian mansions, lush tropical gardens, and the lively streets of Old Town, which are lined with galleries, shops, and restaurants.
The area offers a sophisticated yet laid-back lifestyle, with activities like sailing, fishing, snorkeling, and diving just minutes away. Famous landmarks such as the Ernest Hemingway House, Key West Lighthouse, and the bustling Duval Street are nearby.
