It’s about to get very busy for a corner in the East New York neighborhood of Brooklyn. In addition to the seven-story building planned at 500 Livonia Avenue, HPD plans another seven-story building spanning 81,435 square feet at 453 Hinsdale Street. The former will have 90 units while the latter will have 62 units, though the Schedule A seems to indicate 59 units. Those apartments will spread across 69,634 square feet. If the number is indeed 62, that means units will average a spacious 1,123 square feet apiece. A 1,094 square-foot community facility and 10,707 square-foot retail space will be on the ground level, plus storage for 31 bicycles. Like 500 Livonia Avenue, Christine Hunter of Manhattan-based Magnusson Architecture and Planning is the applicant or record.
