Musician Michael Feinstein has a $17.9 million brownstone duo.

Feinstein bought the townhome on the left for $3 million in 2004, according to The New York Times. A year later, the one next door went up for sale for $3.825 million, and Feinstein purchased, gutted, and renovated it to connect the two.

The finished product features 18 rooms, twin staircases, seven bathrooms, two powder rooms, eight fireplaces, a 25-foot-wide backyard, and two pagodas, which serve as outdoor living and dining areas. He put the mansion on the market for $17.9 million in 2013, but later decided to keep it.
