A duplex at the uber-luxe co-op at 740 Park Avenue said to belong to conservative billionaire David Koch — the unit description matches previous reports describing his apartment at the Upper East Side building — has hit the market for $29.5 million.
The five-bedroom, five-and-a-half-bathroom unit on the fourth and fifth floors features matching upholstery on its walls and sofas. It also has a curved staircase, wood-burning fireplace and three staff rooms.
It was last on the market in 2008, when the asking price was $29.5 million. Kyle Blackmon of Brown Harris Stevens has the listing.
