In the designs of the world-renowned architect Rafael Moneo, such as the National Museum of Roman Art, the Stockholm Museum of Modern Art, and America's largest, most religiously diversified Cathedral of Our Lady in Los Angeles, as well as many other public projects, we can see his pursuit of the eternal nature of the buildings. Roca's Vatican bathroom series, designed by him, is a truly masterful work of design: the building block design gives each part an indispensably close link with the overall structure, providing a fluency and tolerance in which the upper and lower parts are cleverly matched.
