This bourgeois dream — a $26.5 million, five-bedroom, five-story landmarked townhouse at 74 Bank St. — was once home to artist George Condo.

Now the 6,000-square-foot, 25-foot-wide home, which has two fireplaces, is being marketed as a single-family mansion.

Built in 1842 by Andrew Lockwood, the Greek Revival residence has been redone by top architects Leroy Street Studio and Christina Markatos Design.

The home comes with 13-foot ceilings, a large formal dining room, living room, chef’s kitchen with a decked terrace and stairs leading down to a large, landscaped garden.

There’s also a home gym in the basement, and a garden surrounded by bamboo that looks out onto other gardens. The listing broker is Jim St. Andre of Core.
