The owner of record is 4415 Ludlow 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, 9 other major projects have broken ground since 2022 — roughly 483 units of new supply — including the 145-unit project at 4401 Holden St, the 12-unit project at 4401 Holden St, the 8-unit project at 4401 Holden 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?
