Description

WELCOME HOME TO THE SAINT JOHN'S CONDOMINIUM: a true loft in Greenwood Heights Brooklyn, thoughtfully converted from an architecturally notable schoolhouse built in 1905 of Harvard brick and terracotta. The expansive space features a welcoming entry hall that leads to a tremendous great room, highlighted by a bank of original oversized arched windows overlooking a beautiful tree-lined street. The entire living/dining space and open kitchen are bathed in natural light and enhanced by 12.5' tall beamed ceilings. The 1020 sq. ft. loft has been outfitted with custom designed sleeping areas that provide ample space, light, and comfort. They are framed by majestic built-in bookcases and gorgeous solid wood and glass-paned doors. Plenty of room to live, work, and play! Other features include hardwood flooring throughout, a lovely tiled bathroom and in-unit washer/dryer. A sought-after pre-war condo loft conversion, The St. John's Condominium is an elevator building with a tremendous shared roof deck offering spectacular city, river and Statue of Liberty views. More outdoor space than you could ever need! The condominium has a live-in super, is pet friendly, allows subletting, and offers low monthly costs which include heat and hot water. Nearby you'll find loads of cafes and restaurants: Lot 2, Greenwood Park, Quarter Bar, and Southside Coffee to name a few. There's a wonderful playground on 19th & 6th, plus Brooklyn's famous green spaces Prospect Park and Greenwood Cemetery.
