Gary C. Werths Building at Siteman Cancer Center

Washington University School of Medicine / Barnes-Jewish Hospital’s Siteman Cancer Center is a landmark home for unparalleled patient service, multi-specialty cancer care, and thriving research.

The 657,000-square-foot ambulatory care center for Siteman Cancer Center at Barnes-Jewish Hospital and Washington University School of Medicine is located at the corner of Forest Park and Taylor Avenues. The nine-story building features 238,560 square feet of occupied medical space and a 243,250-square-foot parking garage.

Connected to the Washington University Medical Campus by a pedestrian link, the ambulatory cancer center features 96 exam rooms; 88 infusion bays; radiology, breast imaging, and chemistry laboratory departments; 430 parking spaces above the main lobby on floors two through four; and a three-bay loading dock in the lower level. This project is the latest addition to the medical campus that continues to expand east into St. Louis’s Central West End.

The lower level accommodates back-of-house operations such as mechanical and electrical rooms and a loading dock. The first floor includes the main lobby, a multispecialty clinic, retail pharmacy, boutique, and conferencing space. Floors two, three, and four comprise the parking structure. Floor four offers an enclosed walkway to the rest of the Washington University Medical Campus. Floors five and six house 88 all-private infusion bays, 44 on each floor, as well as multidisciplinary exam rooms, an infusion pharmacy, hematology and chemistry labs, phlebotomy suites and staff support spaces. Floor five occupants are able to see two roof gardens to the north and south. Floor eight is another clinical space where most of the imaging – MRIs, CTs, PET CTs and more – will be performed along with additional exam rooms. Floors seven and nine are shell floors for future use. The penthouse stores large mechanical equipment and elevator machinery. Patient drop-off areas were constructed at street level and each of the three parking levels.  

The design and construction of the exterior curtain wall is unique to the building’s purpose and helps disguise the three floors of parking. The design focus is DNA strands (constructed from vertical metal fins) which are depicted in Siteman’s signature blue. Depending upon how the sunlight hits the strands, they’ll be dynamic.
