South Side Spaces is a property management and development company specializing in the renovation and revitalization of historic buildings in the south city neighborhoods of Gravois Park, Benton Park West, and Marine Villa. The company focuses on transforming long-vacant structures — many sitting empty for five years or more — into vibrant, functional spaces that preserve their original architectural character. Their work includes an eclectic mix of artist studios, retail storefronts, office spaces, and residential apartments and homes.

South Side Spaces prioritizes small, independently-owned businesses as tenants, actively working to foster diverse, economically healthy urban communities. The company deliberately avoids renting to predatory financial businesses and is thoughtful about how commercial storefronts are used to maximize foot traffic and neighborhood vitality. Their preservation and community development work has earned recognition from organizations including the Landmarks Association of St. Louis, Missouri Preservation, and the City of St. Louis. Led by owner Jason Deem, the team handles all aspects of property development and management, from project planning to leasing, maintenance and marketing. South Side Spaces is rooted in the belief that historic buildings provide the ideal foundation for new ideas and a stronger, more connected community.
