Description

Available for the first time in 60 years, this historic 20-foot-wide brownstone beautifully connects contemporary Park Slope living to Brooklyn's glorious past, just one block from Prospect Park. Occupied by only three families since its construction, this lovingly maintained residence is the perfect move-in ready home or a flexible backdrop for your personal touches. Talk about Historic Brooklyn. A traditional vestibule entry invites you inside to discover stunning hardwood floors, intact millwork and abundant natural light throughout the elegant parlor level. Grand double doors reveal the inviting front parlor topped by soaring 11-foot ceilings. A stately fireplace anchors the space, and extra-tall windows feature ornately carved enframements and the original shutters that can be found on all street-facing exposures. A shouldered archway adds grandeur while concealed pocket doors reveal a dramatic library surrounded by built-in cabinetry, a fireplace, an authentic pier mirror and lush backyard views. An adjacent study is the perfect spacious and bright home office. On the garden level, the formal dining room welcomes gracious gatherings with its generous footprint, gorgeous wainscoting, built-in buffet and fireplace. The adjacent butler's pantry aids in effortless entertaining, and the sprawling eat-in kitchen is filled with extraordinary southern sunlight. Painted tin ceilings, exposed brick and the original wood-burning stove nod to the home's historic origins while the large pantry adds convenience for busy modern households. Outside, the delightful garden creates a tranquil urban oasis for al fresco dining and lounging under the canopy of a giant maple tree. Inside, a powder room, closets and laundry complete the lower level. Head to the home's skylit top floor to discover serene private quarters. A front-facing owner's suite includes an enviable walk-in closet and a traditional dressing area with a built-in basin that connects to a second large bedroom. The third bedroom overlooks the garden, and a lovely stained glass skylight illuminates the full bathroom. This home's expansive layout could easily accommodate the addition of extra beds, baths or even a family room. Built in 1887, 434 8th Avenue is a Neo-Grec brownstone with handsome Renaissance Revival facade details, including carved panels and bold brackets contrasted by rusticated stone. A traditional high stoop entry and forecourt garden add magnetic curb appeal. Situated on a quintessential tree-lined street between 7th and 8th avenues named one of the greenest blocks in Brooklyn by the Botanic Garden this home offers a front-row ticket to Park Slope's best shopping, dining and (in the post-COVID future) nightlife. Just minutes away, Prospect Park delivers 586 acres of verdant outdoor space and recreation, including the bandshell, music island, the Picnic House, dog park and two year-round greenmarkets. Transportation from this world-famous enclave is effortless with F and G trains right outside your door, 2/3 and R trains within easy reach, plus excellent bus service and CitiBike stations. Listing agent is a trustee of the trust that owns the house.
