The owner of record is Gy Poplar C Development L P. 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, 10 other major projects have broken ground since 2022 — roughly 785 units of new supply — including the 78-unit project at 1000-10 N Delaware Ave, the 55-unit project at 828-40 N 2nd St, the 97-unit project at 500 N Christopher Columbus Blvd. 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?
