Nelson-Atkins Museum in Kansas City by Steven Holl

The translucency of watercolor usually has little in common with the hard surfaces of modern buildings. Thanks to New York architect Steven Holl, it now shines through in the new extension of the Bloch wing for the Nelson-Atkins Museum in Kansas City, which will open to the public on June 9.
A lot was at stake. This is one of the most important collections in the American Midwest. To avoid disfiguring the original museum building, a temple with a high column order built of limestone on top of a hill in 1933, Holl buried most of the 15,000 m² new extension underground. Of the 250-meter length, only a composition of glass sculptures (skylights) remained on the surface, scattered in the garden behind the main building.
