One of the largest adaptive reuse projects in St. Louis, City Foundry transforms a historic industrial complex into a mixed-use destination spread across roughly 310,000 SF. The two-level main foundry building holds 200,000 SF on the ground floor, anchored by a 30,000 SF food hall with 20 vendor stalls and ringed by office suites with separate entrances, retail, and restaurants. A second level adds 50,000 SF of office and restaurant program, with mezzanine offices wrapping a central restaurant and patio and the original foundry pits adapted as flexible tenant space. An adjacent 60,000 SF historic building completes the complex, with lower-level office and restaurant and a ground-floor grocery

MEPFP Engineering ran across both historic buildings and the two additions. Routing modern systems through structures never designed for any of these uses meant sequencing infrastructure around historic fabric in close coordination with the architect through every phase, while keeping tenant fit-out flexibility open for the building’s eventual occupants.
