The appropriately named Old North St. Louis/Crown Square, a joint venture of Old North St. Louis Restoration Group and Rise (formerly RHCDA), began with the creation of an urban master plan designed by Rosemann. For the commercial district, Rosemann worked closely with the partnership and community members to recapture the area’s once vibrant atmosphere by creating a design that facilitates the return of urban retail, office and residential infrastructure.
With the adaptive reuse of 28 historic buildings the area has been transformed into 80 loft apartments and "live/work" units, as well as 34,000 square feet of commercial space. The former pedestrian mall and adjacent streets have undergone $32 million of construction to reconnect the commercial district with its surrounding neighborhood.
The development also includes the installation of new street and pedestrian lighting, public green spaces and landscaping, and a "transit plaza" that facilitates ease of use and transfer of vehicular, pedestrian, bicycle, and public bus transportation. The development will enhance the "walkability" of the neighborhood and solidify the goal of maintaining economic diversity in the community.
