470 9th Street
About This Property
This historic home is one of Park Slope's earliest and most beautiful Queen Anne townhouses and displays all the hallmarks of the style: the Romanesque arches, the massing of shapes and forms, as well as the use of different sized windows, loggias, ornamental cast iron and pressed metal, and terra-cotta and stained glass. The varying rooflines, dormers, oriels and hooded window frames are delightful.
Unlike many Park Slope brownstones, 470 9th Street was never carved up into multiple dwelling units, so original details abound, including six fireplace mantles, exquisite woodwork, stunning stained glass windows, crown moldings, parquet floors, a gorgeous staircase, and much more. The current owners went to great lengths to preserve these historic details while completing a seamless renovation.
Coming home to 470 9th Street you'll ascend a tall stoop, pass through a wood paneled foyer and arrive at the parlor floor, where the ceilings soar over 10-feet high. An elegant procession of spaces leads to a fully equipped chef's kitchen skillfully melded with the room's original historic details. The dining area steps out to a sun-drenched south-facing deck perched high over the backyard. Steps lead down to this tranquil and verdant refuge from the bustle of Brooklyn, which is a perfect place to relax, entertain, and enjoy everyday life. Upstairs you'll find four large sunny bedrooms, two spacious windowed bathrooms, and an array of original details. The third floor front bedroom features a story-book view through a wide-arched loggia, complete with all its original ironwork and tiles.
Downstairs the garden apartment features its own access from the front garden and from the main stair, and is turn-key as a high-income rental, guest suite, home office, or as a seamless extension of the house. The cellar is equipped with updated mechanicals and lots of storage space.
470 9th Street sits in the heart of Park Slope, and is close to the restaurants, boutiques, and amenities that have made this great neighborhood famous. Prospect Park is practically at your doorstep, and the F & G trains are less than half a block away for a short commute to Manhattan and the rest of the city. Come see this historic gem and make it the backdrop for your next chapter in Brooklyn.
