The same people who converted 397 First Street in Park Slope into a condo—now sold out—have sent along a peek at their next project, another townhouse-to-condo transformation. That’s the exterior, above. This building has fewer offerings than its predecessor, with just four full-floor units, all two-bedrooms, two with outdoor space. (Too bad for the residents of the second and third floors.) Prices will range from $1.05 million to $1.8 million. Seems not too bad, though it’s hard to tell without floorplans.
