Description

Make your Park Slope brownstone dreams come true! Location, Location, Location! Situated just three short blocks from Prospect Park, a few blocks from the F/G/R trains, and in between the bustling shops of 5th & 7th Avenue, 421 6th Street is the stuff brownstone dreams are made of. This turn of the century quintessential Brooklyn brownstone is dripping in original details. The home's graceful arc entryway is an exceptional way to enter your new home. Once in the foyer, you'll appreciate the craftsmanship of the original hand-carved wood pier mirror and staircase. The parlor doors invite you to proceed to the sun-drenched front room equipped with one of five original marble fireplaces mantles, 12ft high ceilings, decorated with plaster details like ceiling medallions and crown molding, oversized windows with original wood shutters. The front and back parlors provide two distinct conversation/seating area configurations. This is an extraordinary space to entertain as the parlor flows conveniently into the formal dining room through two arched sliding doors. In the dining room, the parlor floor's second fireplace balances the stunning ornamental wall cutout, ideal for a credenza or impressive home bar. The kitchen is just beyond the dining room, in the extension - providing a wonderful opportunity to renovate and redesign your very own chef's kitchen. Enjoy nights out on the back deck after dinner or head down to the lower landscaped garden to enjoy a nightcap. This home was built for hosting! The second floor is home to the opulent south-facing primary bedroom. Arc detail plasterwork provides the most decadent alcove for a king-sized bed. Relax and curl up with a book in front of your very own bedroom fireplace - ideal for a cozy seating area to unwind. Proceed down the hall to a second bedroom with gorgeous inlay parquet flooring and another marble fireplace. There is a spacious full bathroom on this floor as well. The third floor is home to the third, fourth, and fifth bedrooms, walk-in closet space, and another full bathroom. All this and a high-income garden rental apartment with a full cellar as well! Will be delivered vacant.
