Commercial real estate titan Bob Knakal is listing his Upper East Side home for $13.45 million.

The swanky digs are on the 11th floor of 737 Park Ave., which developer Harry Macklowe converted to condos from rentals after buying the building in 2011.

Knakal purchased the five-bedroom, 7½-bathroom unit in 2015 for around $12.92 million. At 4,719 square feet, the posh pad comes with a private elevator landing that opens to a central foyer leading to an 850-square-foot living and dining room area.

There’s also a windowed chef’s kitchen with a pantry, a separate laundry room and a staff room with its own entrance.

The unit boasts high ceilings, triple exposures and custom upgrades. The main bedroom suite is 1,000 square feet and features three walk-in closets, a windowed dressing room and two windowed marble baths.

Another bedroom has been converted to a library with cherry wood paneling on the walls, the ceiling and the cherry pocket doors, along with a custom wet bar and marble floors. Design details throughout the smart-wired home include oak floors, custom casement windows, lighting and surround sound. 

The 21-story red brick and limestone building, which dates to 1940, features a skylit gym, a children’s playroom, a garden room with a catering kitchen — and bike and stroller storage.

The listing brokers are Douglas Elliman’s Lisa Simonsen and Charles McDonald.
