The Kunsthaus Zürich is a place for inspiring encounters with art. A $230 million extension by London-based David Chipperfield was opened in 2020. Half of the extension's budget came from the city and canton of Zurich, with the other half provided by private donors. Chipperfield's design is a massive rectangular sandstone-covered building. The extension will add 5,040 sq ft (468 m2) of galleries, increasing display space by 78%. The Kunsthaus is now the largest Swiss art museum
