A custom three-story home built on the top of a chic Upper East Side building has sold for $21 million in a speedy all-cash deal.

The buyer, we hear, is a local hedge funder with three kids who attend school in the neighborhood.

The seller is real estate mogul Rodney Propp, who paid $20.37 million for the home in 2018.

The seven-bedroom triplex penthouse, at 360 E. 89th St., hit the market for $22.5 million in late April and took just three weeks to find a buyer. The deal closed on July 11, sources say.

The Yorkville triplex was designed by AD100 firm SheltonMindel, and it made the pages of a shelter mag, which called it a “fairy tale.”

The home comes with a chef’s kitchen, a formal dining room, a media room, two home offices and a 2,529-square-foot wrap terrace. Design details include white oak plank floors — and a double-height, 22-foot-high living room with glass walls, and a concrete and blackened-steel fireplace with a concealed media screen.

A top-floor bedroom suite features a spa-like bath and a yoga room. The building, known as Citizen360, comes with a gym, a lounge, a spa, an art studio and a music room — all in a 34-story, 82-unit building that was completed in 2017.
