Integrated Design Experts

Our approach to providing expert design services is rooted in the belief that architecture, interiors, planning and branding are essential components to overall project success. We believe disciplines should not be treated as phases that happen sequentially, but should be integrated from day one.

Interior Excellence

Ranked as one of the largest interior design firms by the St. Louis Business Journal for 14 consecutive years, Gray’s interior design team is responsible for planning four million square feet of diverse commercial environments annually. From signature two-story office spaces to minor tenant improvements, each project carefully balances functionality, efficiency and aesthetics to create a welcoming atmosphere.

Enhanced Experience

Our interior design approach marries stakeholder priorities, life cycle costs and appropriate finish selections to create thoughtfully planned spaces. Successful interiors enhance the user experience, are easily adaptable and offer flexibility to meet a diverse set of needs. Whether the facility is an early childhood center, high-tech lab or a bustling commercial office, our mission is to design an engaging environment that reflects the client’s mission, vision and brand.

Workplace Strategy

Gray Design Group’s methodology for workplace strategy centers around generating spaces that are innovative, comfortable and inspiring for collaboration and engagement. Our commercial design process prioritizes movement and interaction, helping our valued partners to attract and retain top talent. As part of our proven methodology, we take into account future expansion needs, departmental adjacencies and spacial efficiencies to produce a truly custom design.
