Piedmont Park Square is a new eight-unit luxury condo complex at 21 Piedmont Street in tiny Bay Village. It's a mutt of a building, with a mix of rowhouse-style condos and single-level ones. The first rowhouse-style number just dropped through Gibson Sotheby's. By the look of the renderings, it's an airy affair with an open floorplan and plenty of natural light. The 3-BR, 3.5-BA also comes with a 600-square-foot private deck if you want to get really airy.
