Rare industrial flex opportunity in the heart of Kirkwood, MO. The property at 807 S Fillmore Ave offers a unique combination of private office space and covered outdoor storage in a highly functional layout suited for contractors, distributors, fleet operators, or equipment-based businesses. The site includes approximately 600 square feet of finished office space providing a comfortable owner/operator base of operations, along with a 31' × 63' (1,953 SF) covered outdoor storage pavilion with an impressive 15-foot clear height — ideal for oversized equipment, vehicles, building materials, or inventory requiring weather protection. In addition to the pavilion, the property features a dedicated open-air yard area for vehicle and equipment storage, making this one of the few Kirkwood properties offering this level of outdoor utility. Located on S Fillmore Ave in Kirkwood’s established industrial corridor, the site offers convenient access to I-44, Kirkwood Road, and the Kirkwood Amtrak station. The property is offered on a Full Service Gross (FSG) lease basis at $3,500/month, simplifying occupancy costs for the tenant. A 3+ year initial term is required, with the agreement continuing on a month-to-month basis at term’s end. This is an excellent opportunity for a business seeking a secured, functional, and well-located base of operations in Kirkwood’s industrial submarket.
