Founded in 2000 by Michael and Anne Killeen, Killeen Studio Architects has built a reputation on thoughtful design and enduring craftsmanship. The firm operates from the Killeen Building at 3015 Salena Street, a historic 1886 factory building in the Benton Park neighborhood that the Killeens themselves restored over a decade. The renovation, recognized with the Landmarks Association of St. Louis’ “Most Enhanced” Award, transformed a deteriorating industrial structure into a vibrant creative hub housing architects, photographers, attorneys, web developers, and artists. This project exemplifies the firm’s dedication to revitalizing historic spaces and fostering community through design.

The firm’s headquarters at 3015 Salena Street is located in the heart of Benton Park, a historic neighborhood in St. Louis. The building, originally constructed for stair manufacturing, now stands as a testament to adaptive reuse and architectural renewal.
