And that’s only one of the many possibilities for this unusual Brooklyn property. On a quaint and classic Brooklyn block in Boerum Hill, this three-family row house at 104 Butler Street is currently being used as a source of income from three separate apartments. Through the picturesque garden at the back, a three-story, four-bedroom carriage house is occupied by the home’s current owners. A new owner could leave the setup as-is, use both of these 19th-century houses as a multi-generational home for family, or create condos in the front, with many more options imaginable. The ask is $3.45 million.
