The owner of record is 4620 Umbria 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, 1 other major projects have broken ground since 2022 — roughly 27 units of new supply — including the 27-unit project at 203 Leverington Ave. That kind of concentration is exactly what pulls land values, and buyer attention, toward a block.
