It isn't rising in isolation. Within a half-mile, 7 other major projects have broken ground since 2022 — roughly 411 units of new supply — including the 35-unit project at 208-12 Vine St, the 85-unit project at 230-36 Vine St, the 11-unit project at 225 Quarry 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?
