Transforming Renowned Exhibits

Among Mueller Associates’ extensive portfolio for the Smithsonian Institution, the firm has completed numerous projects at the National Zoological Park. The zoo’s Bird House, which opened in 1928, is undergoing a major renovation that will rehabilitate the historic exterior, replace the main entry, and transform the interior to accommodate the new “Marvelous Migrations” exhibit. The exhibit will include immersive animal viewing opportunities, interactive displays, and multimedia educational programs. Mueller Associates is providing complete MEP engineering services for the renovation.

Our work at the National Zoo spans more than a decade. We have also completed a variety of engineering projects to improve animal habitat areas, conservation spaces, security systems, and visitor amenities. Recent projects include the Conservation Pavilion and improvements to the Great Ape House, Giant Panda Habitat, American Bison Yard, and Great Cats Exhibit.
