Description

Once in a lifetime opportunity (or rather, once in several lifetimes), to acquire what is possibly the most grand and architecturally significant Brooklyn residence to be offered to the general public in nearly half a century. This home is the ultimate trophy home in Brooklyn, the pinnacle of distinction and spacious grandeur. The finest example of neo-Classical architecture in the historic district, if not in all of Brooklyn, this monumental 50-foot wide limestone mansion retains many of its original architectural details, including huge public rooms clad in rare woods, sweeping Gone with the Wind staircase, intricate plaster details, 8-foot high Italian marble fireplace, and a grand marble entry hall with bronze doors and vaulted ceiling. It is a symmetrical house with an imposing, curved central bay, and four fluted, modified Corinthian columns at the entrance. The entire home is of exceptionally fine quality, an elegant composition that is as breathtaking as it is dignified. For the discerning buyer looking for the absolute trophy home, this residence can be restored to its former grandeur. Covering three full floors, plus a garden level, the impressive floor plan affords unlimited possibilities to create an extraordinary and unique mansion. The spaciousness of the rooms and height of the ceilings offers an unparalleled opportunity never before seen in Brooklyn. Designed as a private residence for the Tracy family by the legendary architect Frank J. Helmle, the property has had only three owners since it was constructed in 1912. The property has additional undeveloped air rights that would potentially allow expansion and use as a residential development site, an educational facility, medical offices, NGO, cultural center or museum. The possibilities are limitless. All inquiries will be held in strict confidence.
