A LEED Gold Headquarters for a Commercial Real Estate Leader

Cassidy Turley Headquarters
St. Louis, Missouri, USA

“It looks fabulous. HOK’s design team did a great job and everyone is pleased with the results.”

Gary Helminski
Managing Director, Cassidy Turley

Located in the HOK-designed Centene Plaza, Cassidy Turley’s new headquarters unites business groups and enables the real estate provider to offer truly integrated services.

The design helps Cassidy Turley attract and keep talented people in an office environment that helps them work productively.

Brokerage, property management, corporate services personnel and support staff can work side-by-side in this office. Employees with complementary positions share office space. All shared space is easily converted to extra conference rooms. Personal workspaces accommodate “heads-down” work and promote interaction among co-workers.

The open office space features individually adaptable workstations. To encourage informal meetings, work stations are equipped with either a guest chair or a rolling file cabinet with a cushioned top.

Sustainable features include locally-sourced materials, low- or no-VOC paints and adhesives, and products with high recycled content.
