Inside Netflix’s ‘Sirens’: where Julianne Moore and Kevin Bacon’s luxe mansion is actually located

Julianne Moore’s character might be keeping secrets in Netflix’s Sirens, but the show’s true scene-stealer is no mystery to sharp-eyed architecture fans. The moody thriller, which debuted May 22, has already garnered praise for its A-list cast, elegant styling, and a haunting setting that feels as luxurious as it is elusive.

Set in a fictional waterfront enclave of extreme wealth, the series uses real-life Lloyd Harbor, New York, as its backdrop. The exclusive hamlet is known for housing celebrities and titans of industry, and Sirens taps into that aura of old money and hidden sins with delicious precision.

A country club disguised as a mansion

The jaw-dropping mansion belonging to Moore and Kevin Bacon’s characters, Michaela and Peter Kell, is not a mansion at all. In reality, the imposing property shown throughout the Netflix series is the Caumsett State Historic Park Preserve. Built in 1921, this historic estate originally served as a country club and hunting preserve before becoming a New York State park headquarters.

Through meticulous use of CGI, producers morphed the property’s stately brick and stone into a modern Cape Cod-style estate complete with sleek architecture, a glossy black facade, and an elegant pool, none of which exist in real life.

The home features prominently in Sirens, where it functions as a social hub for the show’s elite characters. In real life, the estate remains a serene filming location and preserved piece of Long Island history, surrounded by lush forest and stunning coastal views.

Lloyd Harbor: The real-life luxury behind the fiction

With a population of just 4,000, Lloyd Harbor is a tiny town with an outsize reputation. The area was once home to Billy Joel, Angelina Jolie, and Jerry Seinfeld. Real estate listings from Realtor.com® show that homes here range from $675,000 to nearly $20 million.

Known for its pastel-colored facades and lavish amenities like pools, tennis courts, and sprawling lawns, Lloyd Harbor offers the perfect canvas for Sirens’ world of secrecy, seduction, and social climbing. The show has sparked a fresh wave of interest in the area, drawing attention to its cinematic potential and celebrity-friendly seclusion.

Inside the filming magic of Netflix’s Sirens

While the estate’s exterior was shot in Lloyd Harbor, the series’ chic interiors were built from scratch at Steiner Studios in Brooklyn. There, production designers constructed spaces worthy of the show’s powerful cast. Priceless paintings, sleek sculpture work, and shadowy lighting all add to Sirens’ immersive and stylish atmosphere.

Early reviews for Sirens have been largely positive, with critics praising its “fine performances” and “complicated depiction of bickering and bruising sisters.” Rotten Tomatoes has already clocked the show at 78 per cent, and buzz continues to build around the layered performances of Meghann Fahy and Milly Alcock.
