The Netflix series Sirens won over viewers with its sharp and funny writing, and one of its impressive factors was the cliffside mansion belonging to Julianne Moore's Michaela Kell/Kiki. The limited series on Netflix follows estranged sisters Devon DeWitt (Meghann Fahy) and Simone DeWitt (Milly Alcock) throughout a weekend.
Devon has come to confront her sister Simone for abandoning their father. Simone now works as the PA for billionaire Michaela Kell and is currently at her boss's estate at Port Haven. Consisting of five episodes, Sirens follows Devon's attempts to snap Simone back to reality.
“Devon thinks her sister Simone has a really creepy relationship with her new boss, the enigmatic socialite Michaela Kell. Michaela’s cultish life of luxury is like a drug to Simone, and Devon has decided it’s time for an intervention, but she has no idea what a formidable opponent Michaela will be. Told over the course of one explosive weekend at the Kells’ lavish beach estate, Sirens is an incisive, sexy, and darkly funny exploration of women, power, and class.”
Adding to the vibe of the series is the impressive estate that one may believe to be a set but is very much real.
The exterior of Sirens' Kell Estate was filmed on location:
On May 26, 2025, Town & Country Magazine published a story that revealed the interesting details behind the location of the estate seen in Sirens. The said article included quotes from several crew members of the Netflix show. Production designer John Paino revealed that while the exterior shots of the house were filmed outside in Long Island's Northport, they needed some production techniques,
“We found a house that was on a great location, and literally on a cliff, but it certainly wasn't big enough. So, we built facades, we put pergolas outside, we extended it, and we built the bottom of a lighthouse. We did all these volume extensions on an existing house in a very postmodern way, in a very simplified classical architectural way.”
Paino further spoke about Sirens' production team's efforts to hint at Kell family history through certain props,
“One of the backstories for the Kell family’s wealth is that it comes from whaling days. So, we also built a 40-foot-long anchor that we put on the property. When you walk on a property like this and you see a giant anchor, it could be from a whaling ship or could be so beautifully created that it could be a work of art.”
If Meghann Fahy is to be believed, the size of the estate makes it scary:
Praising the work of the production team, actress Meghann Fahy expressed wonder at the estate featured in the limited series. Fahy's exact words to Town & Country Magazine were,
“In terms of the sheer size of those spaces, there's just so much that you can't see, and in that unknown, anything can happen. That's what sparks fear, when you can’t truly see people or what they’re doing. Your imagination can run to a much scarier place than what reality might be.”
John Paino then recalled showrunner Molly Smith Metzler telling him that the estate belongs to someone hailing from oligarch money from Nantucket Island. But Paino was also influenced by Greek mythology to design the estate and its grounds,
“This is oligarch money on an island like Nantucket,” Paino recalls, “But there also the mythological aspect of sirens, and so we had to call back to Greek mythology and its oracles and temptresses.”
To design the estate, Paino looked at numerous Greek heritage structures, including the Oracle of Delphi, and incorporated their elements into the set,
“it's a show that actually uses the architecture of the sets. It's not just decoration; it has structural means.”
Other than historical Greek structures, the production team also incorporated elements of the Winchester House, which is located in San Jose, California. One of the highlights of this historical mansion is that it consists of several rooms and hallways that go nowhere. Legend has it, this was done to confuse any possible spirit.
Sirens is currently streaming in its entirety on Netflix.
