Vito Errico, who co-founded the high-end gym brand Equinox with his siblings in 1991, hasn’t lost his flair for the fancy.

Now, a custom-built contemporary stone home in Armonk, NY, that he co-designed is on the market for $8.88 million.

The 11,423-square-foot “hotel at home” at 21 Sterling Road South is an assemblage of smaller buildings connected architecturally, notes broker Lesli Hammerschmidt, of Houlihan Lawrence, notes.

“It wasn’t about building a grand, in-your-face mansion, but a home where my family and friends can enjoy their surroundings and one another,” Errico tells Gimme Shelter.

The six-bedroom property, which dates back to 2006, was designed in collaboration with Carol Kurth Architects and Five Star House, the team that also originated Equinox’s designs.

Highlights include an indoor pool and a spa area that is covered by a retractable glass A-frame roof.

There’s also a billiards room, a home theater, a wine room and a recreation room including a “commercial-grade” gym with an indoor sports court.

Outside, there’s a stone terrace with an outdoor barbecue and a fire pit.
