It isn't rising in isolation. Within a half-mile, 12 other major projects have broken ground since 2022 — roughly 582 units of new supply — including the 9-unit project at 1700 Frankford Ave, the 40-unit project at 1716 Frankford Ave, the 55-unit project at 1713 N Front 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?
