This study is focused on three major museum projects completed during 1990's by Richard Meier who is known as the romantic modernist as well as one of the architects who continue their devotion on completing the fourth dimensional spatial concept through the practice. Main focus of the study will be analyzing the space and design elements shown in the Museum of Contemporary Art (Barcelona, Spain, 1986-95), Museum of Television & Radio (Beverly Hills, CA., 1994-96) and the Getty Center(Los Angeles, CA., 1984-97), and find out the new meaning of museum design suggested by the architect. The analyzation was done based on the actual sight visits and through the acquired references. The museum designs done by Richard Meier show consistency between visual language, use of 'light, space and form' as the design elements to connect interior and exterior to create openness and harmony with surrounding condition. Additionally, greatness of the architectural elevation, efficient use of interconnecting space, adoption of natural light, affective use of the space, careful consideration to the exhibiting items, spread of information centers, balance between large and small exhibition spaces, and his concept on providing choices to the viewer within the museum are the main issues in designing the museum in order to give various spatial experience to the visitors.
