Upon review of Missouri Housing Development Commission (MHDC) documents, it appears that the vacant corner building at Grand and Gravois (3552 Gravois) may be rehabbed into affordable apartments. The project is (tentatively?) known as Southside Station. The Lawrence Group is shown to be the contractor. The project is shown here in the application phase. It has since advanced to the “conditional commitment” phase.
Below is a Google Streetview shot of the building.
