Long Island, Gold Coast, New York
A rare legacy estate on Long Island’s Gold Coast, Swan Manor comes under the hammer this July as one of the main contenders for a trophy title in the auction. Envisioned by famous architect Stanford White and spread across nine secluded acres with all-encompassing views over the Long Island Sound, the property marries heritage with quiet modernity, spanning 22,000 square feet across three separate residences. A feat of architectural design, this 14-bedroom, 14-bathroom family estate is one of a kind, a free-flowing home where every detail is intentional, from the heated floors to the handcrafted stone finishes and indoor resort-style pool pavilion with fully functional spa, sauna and gym.
The grounds outside, softly undulating, are built for privacy and calm, and appear plucked out of a surreal landscape, with botanical gardens, a cascading stone waterfall and a Stately bluestone driveway leading to a professional tennis court. A separate three-bedroom guest house and dedicated staff quarters allow for full-time support during intimate gatherings or ample social events.
Swan Manor is part of Nissequogue village on Long Island's exclusive Gold Coast. The area offers access to yacht clubs, private golf, and sandy beaches, and sits just over an hour from Manhattan and within reach of the Hamptons. For those in search of country living with metropolitan access, Swan Manor carries impressive credentials, substance and a quiet prestige that has attracted families for generations.
Siesta Key, Sarasota, Florida
Siesta Key is designed for coastal living that’s as relaxed as it is functional, balancing ease with precision and resort-style living with effortless sophistication within a gated waterfront enclave of Riegels Landing. Serving 357 feet of deep-water shoreline and direct Intracoastal access, this is a dream-like spot for boaters. Inside, the property flows across 3,616sq ft of engineered hardwood floors, floor-to-ceiling sliders, living areas finished with custom millwork, Wolf, Sub-Zero and Miele appliances, multiple pantries, and smart storage throughout.

Downstairs, a fitness room, wine storage with plumbing, and an oversized garage with built-ins complement the offering.
The layout easily moves to the outdoors, with expansive Shellstone patios that wrap around a saltwater pool and spa with integrated fire and water features, all controlled remotely. There is room to park a 50-foot yacht, a floating kayak launch and lit pilings inviting to head out and enjoy quiet living by the water.
The home is offered fully furnished, as a turn-key and move-in ready option, including Control4 automation that manages lighting, security and AV, and a whole-house generator ready for backup.
Just steps from Siesta Beach and a short drive from Sarasota’s cultural and dining scene, Siesta Key Village beams with open-air restaurants, fresh seafood spots, cafés, and tiki bars where live music plays nightly, all set against the Gulf Coast’s natural beauty.
