Inside ‘Sirens’: How Julianne Moore’s Drama Nabbed Its Outrageous Long Island Mansion

Oh great, another sprawling estate—because nothing says “mystery drama” like a 20-room behemoth dripping in gold accents. That’s exactly the vibe production designer Alex Ruiz chased down for Sirens, Julianne Moore’s upcoming drama series. According to an exclusive with the New York Post, Ruiz scouted no fewer than a dozen properties across Long Island before planting the show’s flag on a 1920s Georgian mansion in Sands Point. And yes, it’s as ridiculous as it sounds.
Ruiz told Post reporters on July 12 that he needed a location “bold enough to match Tim O’Brien’s gothic-tinged script,” which called for secret tunnels, grand foyers, and a ballroom that could host an impromptu séance. Variety corroborated that the chosen estate checks every “box-office-gasp” moment: hidden panels behind library shelves, a mirrored ballroom imported from Paris, and a rooftop terrace with ocean views that cost more in property taxes than some indie productions spend on VFX.
Reports in Architectural Digest add that the owner—a softly spoken hedge fund manager—had to be convinced over multiple Zoom calls that “Hollywood red tape” wouldn’t scar his prized Tiffany windows. Location manager Sara Patel spilled the tea to AD on July 15, admitting they even had to patch up original parquet floors with custom resin to keep the look period-perfect. Meanwhile, the local permit office in Nassau County had to fast-track shoot approvals, a rarity that left officials “just rolling their eyes,” per an insider in the Long Island Press.
Budget? Let’s just say the team’s day rate eclipsed most mattress commercials. Ruiz cheekily told the Post they “capitulated on the budget only after realizing no other house could deliver the same “jaw-dropping backstory” the script demands. Even the catering trailers got the deluxe treatment—French patisserie bites, 24-hour espresso bars, and towels monogrammed with the show’s serpent logo. Because, why not?
So the final product will feature Moore prowling opulent hallways, dodging shadows cast by crystal chandeliers, all while looking every bit the enigmatic heroine we’ve come to expect. And sure, some might call it overkill. But in Hollywood, excess is the new essential.
And there you have it—a mansion that’s more star than the star. You’re welcome.
