Description
This one bedroom loft space at 423 Atlantic Avenue has Southern Exposure sunlight that makes the Avenue shine. Double-paned, oversized windows bring in the light and leave the noise outside. Hardwood parquet floors, and soaring ceilings make the space inviting and hospitable. As you enter the apartment there is a huge walk-in closet on your left and a large eat-in kitchen on the right. At over 900 square feet, this 'pre-war' loft can easily be converted into a two bedroom dwelling. The kitchen is a canvass for you and your architect/designer/contractor to complete.
Dwell in the realm of possibilities. It is rare these days to find a diamond in the rough in Boerum Hill. Especially in an iconic loft coop such as the Ex-lax building. This elevator building is pet friendly, has a meticulously maintained common roof deck with breath-taking 360 degree views; and with 60 residential units, the coop boasts of a much beloved full time live-in super. There is a laundry room on the ground floor, and the elevator has recently been extended to the basement-which is also a blank canvas for the coop to develop. If you are looking create own space without performing a total "gut-job", look no further. Living in Boerum Hill, you are surrounded with some of the best cultural and culinary spaces that New York has to offer. And the public transportation options can't be beat.
