28-unit residential new construction, zoned CMX3.

A 28-unit residential building is set to rise at 1021 N 3rd St in Northern Liberties, the kind of by-right infill quietly reshaping the block. It was cleared to build in Dec 28, 2021.

The owner of record is L W Partners III LLC. The project's plan drawings are on file — worth a look for anyone underwriting the surrounding block.

It isn't rising in isolation. Within a half-mile, 8 other major projects have broken ground since 2022 — roughly 610 units of new supply — including the 10-unit project at 1139-41 N 3rd St, the 166-unit project at 310 W Girard Ave, the 55-unit project at 828-40 N 2nd St. That kind of concentration is exactly what pulls land values, and buyer attention, toward a block.

We'll update this page as the project progresses — leasing, retail tenants, renderings, and construction milestones as they surface. The relevant question for investors and agents: what are the surrounding parcels worth to a builder now that this is coming?
