It isn't rising in isolation. Within a half-mile, 7 other major projects have broken ground since 2022 — roughly 349 units of new supply — including the 31-unit project at 326 N 12th St, the 81-unit project at 225 N 13th St, the 23-unit project at 1314-32 Spring Garden 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?
