August Real Estate Co. now owns the midcentury landmark at 5646 Milton St., promising to preserve its Georgia Pink marble while upgrading a 75-year-old boiler.

The plan replaces a 174-unit SRO with two towers near Madison and Fifth avenues, and would lock in affordable housing rules for the whole block.

The $15 million lands as buildings, not charity checks — and the foundation's CEO gets a downtown board seat to prove it.
