New York, New York
One of the oldest institutions of its kind in America, Columbia Grammar and Preparatory School (pre-kindergarten through grade 12) has been committed to expanding its facilities for more than two decades. In response, IBI Group added an additional classroom floor to the top of three of the brownstones, and a new 2,000 square foot gymnasium with a rooftop play area in the common rear yard. As part of the building consolidation, IBI Group replaced the existing fire escapes at the rear of the brownstones with new open corridors and fire stairs, thereby unifying the seven brownstones into one school, accessible at all levels. An elevator was also added to provide accessibility at all floors. The design is an innovative contribution to the school’s ongoing effort to provide state-of-the-art facilities in the Upper West Side Historic District. This project was approved by the NYC Landmarks Preservation Committee with a Certification of Appropriateness because it is located in the Westside Historic District.
