1125 Pequot Avenue in Southport, CT: Where Wealth is Measured in Perfectly Cubed Foliage

Behind a gated entrance in Southport, CT, at the edge of Long Island Sound, lies 1125 Pequot Avenue, better known as The Nest—a waterfront estate that last sold for $16,500,000 in 2020 (with 2024 property taxes of $248,539!).

Designed by architect Mark Finlay, with landscaping by Doyle Herman Design, the home is perfectly positioned to maximize its scenic location (pics). Set on 3.44 acres, the 11,760-square-foot residence offers 7 bedrooms and 11 bathrooms. The meticulously manicured grounds feature expansive lawns that stretch toward the water, an infinity pool, spa, and private sandy beach—all framed by hedges and trees so precisely trimmed into perfect cubes, they could double as a geometry lesson.

Inside, The Nest blends European sophistication with Scandinavian simplicity. The great room boasts 12-foot coffered ceilings and oversized paned windows, while the library offers a moody contrast with its dark lacquered finishes. The chef’s kitchen is a true standout, featuring Absolute Black granite countertops and a matte black La Cornue range. A rooftop observation deck with firepit provides a true bird’s-eye view of the Sound.

Additional amenities include a four-car garage with guest quarters above, a home gym, and a poolside cabana. On an adjoining parcel, the estate also has a tennis court and a spacious guest home.

Just a short walk away, you’ll find Southport Village, the Pequot Yacht Club, and nearby conservation land.
