Private equity honcho Mark Zittman and his wife Noelle have dropped the price of their mansion at 2 North Moore St. in Tribeca to $34.5 million.

It was originally asking as much as $48 million in 2014 — double the $24 million they paid for the 11,300-square-foot home when The Post outed the Zittmans as the buyers in 2010.

The spread currently has a tenant: a single finance guy paying $95,000 monthly to live in the giant space.

The six-story address — which the couple bought from developer Steven Schnall, whose wife nicknamed the sprawling house “our suburb” — is a whopping 65 feet wide, with 1,500 square feet of private outdoor space.

It features six bedrooms, seven full bathrooms and four powder rooms, along with three fireplaces, a staff apartment with a separate entrance, an art studio, a screening/billiards room and an outdoor dining room.

There’s also a top-level gym with a 50-foot indoor heated lap pool and a high-speed elevator.

The listing broker is Adam Modlin, of The Modlin Group, along with brothers Tal and Oren Alexander of Douglas Elliman.
