Rare opportunity to own a stylish, elegant top-floor condo with ownership of a spacious, light-filled detached 600 square feet artists' studio/home office structure, in one of Somerville's hottest locations. The penthouse is flooded with natural light from multiple custom windows and skylights, including (9 foot) sliding glass doors that open to a stunning, private tree-top deck overlooking a shared back garden and the bike path. The living space features 11-foot ceilings throughout, wide southern pine floors, an open floor plan, and a tastefully designed kitchen. The custom bath includes an over-sized teal-tiled double shower with a built-in bench, a double sink vanity, and two 4x4 foot skylights. The open concept artist/office studio on the ground level is filled with natural light from windows on three sides, including a series of french doors, which look out on, and open to, the shared back garden. The property is about a half-mile to porter/Davis Square and has direct access to the bike path.
