Description

This timeless Park Slope beauty is ready for its new owner to enjoy all of its glorious period details and modern upgrades. Configured as a spacious 5 bedroom triplex over a large 1 bedroom garden unit, this 2 family home can be used as an income producing property or a gracious single family home. The parlor floor boasts 14’ ceilings and a stunning original carved marble mantle. At the rear of the parlor, with views of the lush garden is a pristinely appointed kitchen. Renovated in 2022, the kitchen was designed with an eye for entertaining with an oversized island with casual seating and abundant storage, a large pantry, stylish cabinetry and a deep porcelain farmhouse sink. Leading directly from the kitchen is a deck with stairs to the beautiful backyard. Enjoy the blossoming cherry tree and dine on the deck or hide away in your secret garden below. The third and fourth levels of this home feature 4 large bedrooms and a room that is currently utilized as a home office. Original details abound including gorgeous mantels, shaving sinks and built-ins. Spectacular views of downtown Brooklyn and Manhattan can be seen from the top floor rear bedroom. The extra large primary bedroom showcases the original arched plaster detailing. Two beautifully renovated bathrooms with radient heated floors serve the bedrooms. The 3rd floor bathroom has a stylish large, windowed shower with rainfall shower head and double sink, while the 4th floor bathroom features a charming clawfoot tub and eye catching ceramic flooring. Laundry on the top floor makes for easy living. At the garden level is a beautifully appointed 1 bedroom apartment with 9’ ceilings. The kitchen and bathroom have both been recently renovated and are equipped to either be a guest suite or rental unit. This unit has access to a private section of the backyard, ideally set up to preserve privacy for both a tenant and the owners. An unfinished cellar has untapped potential. Boasting ceiling height of 8’ and a brand new steel center beam, this space could be a future gym, screening room or recreation room. With new windows throughout, new heating system, new roof, and new copper water main, the less glamorous infrastructure projects have been done for you. Just bring your bags and move in. 417 6th Street is ideally situated in the heart of Park Slope. Located on a beautiful tree lined street just 3 blocks from the F/G trains, the YMCA, the Brooklyn Public Library, and a plethora of fantastic restaurants and shops.
