There is some debate as to what constitutes a loft in Boston. High ceilings? Open floorplan? Island in the kitchen? Some combination of all three and more? Whatever the definition, undoubtedly, though, buyers want them. So here comes this unabashedly lofty 3-BR, 2-BA in the Laconia at 1200 Washington Street in the South End. Its ceilings are high; its 2,116-square-foot floorplan is open for the most part; and, most convincingly, its kitchen island is 15 feet long. There's all the other whizzbangery that you'd expect in a luxe building—new appliances in the chef's kitchen; bathrooms with 11 shower heads; maple floors—as well as a garaged parking space for $60K more. For everything else, it's $1,174,000.
