Our History


Sub 4 Development Company was started in 2015 as the real estate development branch of Green Street Realty.  The goal was to build high quality student housing, multi-family housing and retail projects in house and not rely on an outside contractor to build our developments. Since its inception, we have been one of the most active builders in the Champaign-Urbana. Illinois market, building  numerous new construction projects. As we continue to grow, so does our footprint, we have started developing  projects in areas such as  Colorado Springs, CO, Phoenix, AZ, Ann Arbor, MI and Lafayette, IN. In addition to our office in Champaign, Illinois, we have offices in Scottsdale, Arizona and Denver, Colorado. We currently have a pipeline of $1,200,000,000 of ground up multifamily projects.
