A 152-unit residential building is set to rise at 815 Poplar St in Northern Liberties, one of the larger new-construction projects underway in Philadelphia this cycle. It was cleared to build in May 27, 2021.

The owner of record is Poplar Development Property Owner 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, 2 other major projects have broken ground since 2022 — roughly 236 units of new supply — including the 70-unit project at 915-23 N Broad St, the 166-unit project at 310 W Girard Ave. 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?
