As part of its mission to protect and restore our natural resources, the Missouri Department of Natural Resources selected BNIM to design and build an office facility — the Lewis and Clark State Office Building — that showcases affordable and cost-effective 'green' strategies. Utilizing the LEED rating system as an organizing matrix, it provides a template for the State, as well as other Missouri companies, to build in ways that are more respectful of the environment and people. The LEED Platinum building is located on a formerly developed site that sits on a bluff overlooking the Missouri River, where it offers a strong connection to Missouri's resources.

The building has shown a 7.5% reduction in absenteeism and the lowest construction cost per square foot of any other State office building.

The building is organized around a four-story atrium space that opens to a grand view of the Missouri River valley and provides an active central stair to encourage pedestrian circulation. The natural limestone bluffs prevalent along the river influenced the formal qualities of the architecture.

Natural daylighting, as well as sun shading devices, are responsive to the sun patterns throughout the year. The building utilizes the latest advances in daylighting technologies, electrical lighting and control systems, efficient building envelope design and highly integrated and innovative HVAC systems. Wherever possible, systems are expressed to educate the public about how the building works. The consulting group Conservation Design Forum, designed a restorative site plan that minimizes stormwater run-off and emphasizes the native prairie plants and ecosystems.
