We sometimes see a floor plan that makes this much sense, but not often. This window-wrapped Bay Ridge apartment at 6665 Colonial Road currently has one bedroom, but the potential for another–or even two more–is immediately evident. The flow of space through the home makes important spaces like the kitchen and bath easy to get to from everywhere, while keeping private space private. The home’s interiors are sunny and cozy without being cramped. And $399,000 isn’t a number you see too often in New York City, even in well-kept secret Bay Ridge.
