What the numbers suggest

The formal data points released publicly present 1,000+ residential units across a ~1,000,000-square-foot footprint for a 27-story tower with a waterfront park. Combining these figures suggests an average unit size near 1,000 square feet, assuming the stated unit count and total floor area are representative of the residential program. This derived figure, while not explicitly stated in a single source, follows directly from the project’s own figures as described by DeSimone in its project update and Field Operations’ release on the groundbreaking. Original finding: Based on DeSimone’s description of 1,000,000 SF and “over 1,000 residential units,” the implied average residential unit size is approximately 1,000 SF per unit. Method: divide total residential square footage by the number of units; sources: DeSimone update and Field Operations’ groundbreaking release. This estimate helps readers gauge scale relative to typical Brooklyn multifamily product and is intended as a transparent, reproducible metric rather than a marketing claim. (desimone.com)
