The building will serve as the operations office for the Lake Mead National Recreation Area's Cottonwood Cove Resort and Marina, and is expected to take certification at the Gold level.
A ceremony celebrating its LEED registration status will be held on Monday, June 6th, and is open to the public.
The floating eco-friendly structure features sustainable modular construction, energy-efficient and environmentally responsible materials and fixtures.
Its decking is constructed of a composite of rice hulls and recycled plastic; its exterior stucco is made of recycled tires. Low or no volatile organic compound finishes, paints and adhesives will help to ensure indoor air quality for staff members and visitors alike.
Carlson Studio Architecture of Sarasota, Florida, designed the unique floating structure.
"Every building type has the potential to perform at a higher level with integrated environmental considerations," said Project Architect Michael R. Carlson, in a statement.
"We jumped at the chance to work with this team to design a first-of-its-kind, first-class marine facility."
