PEOPLE ARE THE REASON FOR WORKPLACE. THE REASON TO COME TOGETHER.
A Shift in Focus: The Future of Work Metrics
The way we measure the workplace has fundamentally changed — it’s no longer about seats or square footage. ANCHORED IN WELLNESS • Equitable spaces that support all people and work styles • Amenity-rich environments that enhance life beyond the workday • Healthy options for eating, drinking, exercise, and mindset • A reason to show up — a workplace that genuinely works for you • Sustainable by design INTEGRATED TECHNOLOGY » Hybrid work is here to stay » Home environments have become a true extension of the workplace, and the connection between the two must be effortless ADAPTABLE » Kit-of-parts approach allows for reconfiguration over time » Modular format supports evolving needs
A DESTINATION » Attracts and retains top talent » Social hubs that build relationships and trust » Tools that support learning, productivity, and growth » Embedded technology that enables seamless experiences DIVERSE ENVIRONMENTS » Choice-based environments for every work mode » Spaces for outward collaboration and focused individual work » Unique settings with diverse tools and postures that spark creativity » Activity-based design that matches space to task

ADAPTIVE REUSE CASE STUDY
Clayco’s New St. Louis Office
PLANNING FOR HEALTH & WELLNESS We used biophilic design—daylight, vegetation, and natural materials—to reduce stress by up to 30%. The smooth indoor-to-outdoor gym transition and integrated art gallery promote a healthy work-life balance for employees.
SITE IMPROVEMENT
We increased green space by 115%, reaching 162,000 sq ft for groundwater recharge, air quality, and communal areas. Landscaping uses 100% native vegetation for biodiversity and low maintenance. Carbon sequestration will reach 525 tons over 50 years, equivalent to removing 114 cars’ CO2 emissions annually.
The existing building at 8640 Evans Avenue was developed, designed, and built by Clayco in 2012 and was occupied by Express Scripts until 2022. Our team chose adaptive reuse over new construction, significantly reducing our ecological footprint.
