A 15-story, 280-unit tower is under way at 1021 N Hancock Street in Northern Liberties, developed by 1022 Associates LP on a roughly 46,300-square-foot site acquired in 2020. The project cleared its final hurdles in late 2021 and is now rising as one of the taller residential structures in the neighborhood, with ground-floor commercial shell space set aside for future tenant fit-out. The building is being constructed under CMX3 zoning, which allows the height and density by right—no variances, no special pleading, just straightforward mid-rise infill on a parcel that had long sat underused.

Northern Liberties has absorbed nearly 1,000 units within a half-mile of this site in recent years, including the 107-unit project at 1122 Frankford Avenue and a pair of 84-unit buildings at 130 W Girard. The 1021 Hancock tower is larger than any of those, reflecting continued confidence that the neighborhood can digest significant new supply without losing its footing. The developer is banking on proximity to transit, walkable retail along 2nd and 3rd Streets, and the area's reputation as a less-polished alternative to Old City or Fishtown.

What makes this project notable isn't novelty—it's scale and timing. Northern Liberties has been filling in steadily for two decades, but 280 units in a single building is a bet that the fundamentals remain strong even as smaller developers pepper nearby blocks with 10- and 55-unit walk-ups. The presence of shell commercial space on the ground floor suggests the ownership expects street-level activity to follow, though leasing that space in a post-retail landscape remains its own challenge.

For investors and developers eyeing comparable parcels in the neighborhood, 1021 Hancock is a proof point: CMX3 sites with assembly potential can still support high-density projects without rezoning battles. As this tower delivers, watch how quickly similar lots along Girard and Columbia start drawing acquisition interest—Northern Liberties hasn't run out of room, but it's running out of easy parcels.

In the news

What we're hearing about this project

Post Brothers filed revised plans for a six-story, 241-unit building called the Mercato with construction expected to begin in Q4 2026 and completion in 2028.
The Mercato will feature 241 one-bedroom and studio apartments at 1021 N. Hancock St., substantially smaller than earlier 280-unit plans.
The project was scheduled for Philadelphia Civic Design Review on August 4, 2026, with CEO Michael Pestronk calling it one of the final pieces in the Piazza portfolio.
Earlier 2021 permits were issued for a 15-story, 280-unit tower designed by DIGSAU, but the project was later revised and downsized.
