Property owner Gjek Popaj has filed applications for two four-story, nine-unit residential buildings at 1643-1645 Popham Avenue, in Morris Heights, located a number of blocks away from the neighborhood’s Metro-North Railroad station. Each building would measure 5,944 square feet in total, which means the units will likely be rentals, averaging just 660 square feet apiece. Pelham, N.Y.-based Fred Geremia Architects & Planners is the applicant of record. Demolition commenced earlier this week on the existing two-story, two-unit brick building.
