The developers behind a plan to build a large mixed-use student housing complex on Knox Road in College Park have filed detailed site plans for approval by County officials. The filing provides many new details about the project, including the first renderings we’ve seen of the proposed building, and a host of information about building layout and design. The project comes from McClean, Virginia-based developers Greystar Real Estate Partners, which also manages apartment buildings under subsidiary Greystar Property Management Services. The project will have 14,800 square feet of retail commercial space, 334 student housing units, and 251 parking spaces, most of which are located in an underground garage. To make way for the project, developers plan to raze the existing one-story retail strip that already exists on the block.
