Our History


Sub 4 Development Company was started in 2015 as the real estate development branch of Green St Realty, with the goal of building high quality student housing, multi-family housing and retail projects. Since its inception, we have been one of the most active builders in the Champaign-Urbana market, building over $100 million dollars of groundup, new construction projects. As we continue to grow, so does our footprint, with plans on starting multiple out of market property development projects in areas such as Madison, WI, Colorado Springs, CO, Phoenix, AZ, Ann Arbor, MI and Lafayette, IN.
