The Captain Cartwright House

43 Howard Street, Sag Harbor, NY 11963


The meticulously renovated Captain David Cartwright House embodies Sag Harbor Village’s rich whaling history while embracing every modern convenience and luxury, located on one of the most coveted and quiet village lanes.
Built circa 1835, the exquisite example of Federal/Greek Revival architecture has been masterfully re-constructed with period details and historic materials, designed with a thoughtful open flow through expansive sun-lit rooms with state-of-the-art systems and technologies. The 5,000 square foot home on .2 acres with three levels features four bedrooms and four ½ baths with high ceilings, antique crown molding, wainscoting and trim and bleached, white-washed, wide-plank antique pine floors throughout. The beautifully landscaped, expansive back yard includes a heated gunite salt-water pool with a hand-crafted stone pagoda which houses an outdoor kitchen, bar and lounge area.
The front portico is one of the most regal in all of Sag Harbor, a carefully restored Greek Revival entry with fluted wooden columns and pediment, original 8-panelled front door, and Federal style transom. The elegant entrance hall includes a gracious, expanded mahogany staircase with direct enfilade views from the front door through to the outdoor deck, rear garden and pool. Two original double parlors divided by antique mahogany pocket doors have restored 6-over-6 stash windows with original wavy glass and wood-burning fireplaces with period mantlepieces. These lead into a formal dining room with its own fireplace and beamed, coffered ceilings with direct access to the kitchen as well as a working butler’s pantry. A sun-drenched family room with authentic 19th century pine cabinets and fireplace flows from the kitchen to the dining room, opening through French doors onto the back porch. The expansive chef’s kitchen features a top of the line Wolf stove, Sub-Zero refrigerator, and Bosche dishwasher with a custom soapstone sink and countertops with marble and tile accents. It leads onto a back stairway and a mudroom with its own separate entrance.
The second floor has two charming, ensuite light-filled bedrooms with built-in custom shelving and closets and marble and tile filled bathrooms with nickel-plated fixtures. A third bedroom/office showcases vintage nautical maps on the walls and an authentic built-in officer’s bunk from a World War II ship, with built-in book cases and desk. The large master suite opens through antique French doors into a vestibule with a fabulous custom cedar closet from a 1920’s Boston mansion dressing room. The custom-wood-paneled master bedroom with high gabled ceilings features its own gas fireplace and garden views. The master bath is an ode to chic London hotels with floor-to-ceiling marble, deep soaking tub, modern steam shower and double vanity sinks with marble countertops. The suite also includes a large dressing room with custom closets, sliding shelves and storage units with a lounging window seat and access to the back staircase.
The finished lower level has an open great room with sun streaming through windows as well as double French doors leading to the back patio and summer kitchen and includes a fireplace, bathroom with shower, wine cellar, large laundry room, state-of-the-art systems room and storage.
The vibrant village of Sag Harbor is just a stroll away with fine restaurants, boutiques, theaters, museums and a picturesque harbor with magnificent sail and motor yachts. The perfect location to honor past, present, and future.
