Description
645 Carlton Avenue is a charming and quaint, pet friendly, 4-unit Co-op nestled at the end of the row on one of Prospect Heights' most beautiful townhouse blocks. The triple exposure (South/East/West), West-facing bay windows, and rare 24' width are just some of what make this Flats Building so attractive and unique.
The Apartment: Upon entering "Apartment 3" - the full-floor unit on the 3rd floor - you are immediate struck by the many impeccably maintained, original late 19th century details, including the ornate wooden portals, high 10-foot ceilings, original coved crown and baseboard moldings, picture rails and gorgeous hardwood floors with decorative mahogany trim and herringbone patterns.
Living Room - The West-facing over-sized bay windows, wood-burning fireplace, high ceilings, coved crown molding, and ornate portals draw your attention as you enter the 14' x 21'4" large living room. However, equally impressive is the wide and detailed woven diamond-shaped hardwood trim framing the room, the hearth, and the herringbone pattern on the rest of the living room floor.
Study - This 13'6 x 6'5" bonus room is a beautiful space for an open study or an enclosed third room. The afternoon light streams through the oversized, arched window, the hardwood trim is a beautiful deep mahogany and the room is finished with a beautiful built-in, floor-to-ceiling built in cabinet.
Dining Room - The 10'4" x 10'5"windowed, formal Dining Room is situated adjacent to the living room and separated by a wide portal allowing for the option of a 31-foot open expanse or the privacy of a separation with the bi-fold glass-paned doors.
Kitchen - The East-facing, windowed kitchen gives this classic townhouse apartment a modern touch, and features stylish blonde speckled granite countertops, a Bosch gas range and Bosch dishwasher, Frigidaire Professional series side-by-side refrigerator, deep chef's sink and beautiful floor-to-ceiling cabinetry and storage throughout.
Bedrooms - The large, Main Bedroom (15'7" x 12'8") faces East and with two over-sized windows welcoming the morning sunshine. The coved crown molding, 5" baseboard molding, herringbone floors and woven mahogany trim frame the king-sized space and leave additional room for a seating area, work station, or vanity. The 11'9" x 10'5" second bedroom features double exposure (South and West) and a deep closet.
Bathroom(s)/Laundry - The three-piece, windowed bathroom is spacious and features stylish subway tile with black trim with matching floor tile, pedestal sink, deep Jacuzzi soaking tub and additional space for storage, and the adjacent, separate, windowed Laundry room features a vented stackable LG washer and dryer and a storage closet. NOTE: there is a separate plumbing line in the laundry room, so this space CAN be converted to a half bath/laundry (see alternate floorplan and note that all alterations require submission to the board with proper permitting and architectural renderings)
Additional Storage / Bike Storage - Apartment 3 comes with additional, dedicated shelf storage in the basement and all shareholders are encouraged to park their bicycles in the basement as well.
