An extraordinary $8 million investment is set to transform 300 S. Jefferson, elevating an already iconic first class office building into what will be one of the most distinctive and impressive office environments in downtown Springfield. Beginning in early 2027, the property will be reimagined with a fully renovated first floor, new event center, private courtyard, catering kitchen, collaboration and meeting spaces, conference facilities, upgraded lighting, security, windows, and other significant architectural enhancements. Combined with its landmark design, attached parking, flexible office configurations, and premier downtown location, this investment will set 300 S. Jefferson apart from every other office offering in the market. The result will be a polished and thoughtfully designed, welcoming and memorable environment for tenants and guests, and a clear long-term commitment to quality that further establishes 300 S. Jefferson as the premier business address in downtown Springfield. Available suites range from approximately 329 SF to 11,337 SF, with larger full-floor and multi-floor opportunities up to approximately 34,929 SF.
