Designed by Finnish architect Pekka Vapaavuori, the building contains a collection of art from the 18th century through to 1945 on its first three floors, a collection of art from 1945 to 1991 on the fourth floor, and contemporary art exhibitions on the fifth floor.
Like many contemporary museums, KUMU (KunstiMUuseum) is designed to be multifunctional. It has a 246 seat auditorium, lecture and meeting rooms, spaces for concerts, events, conferences and performances.
The museum also contains a teaching centre with study rooms and all the facilities required to educate young people about contemporary art. The first floor also has a dining area with a bar, coffee shop, restaurants, and patios with views over Kadriorg Park.
The museum complex fits into its setting with its curvaceous, almost circular shape which makes way for itself in the greenery and the city with clear but discrete lines. At night the museum is present in the form of a series of slits or blades of light cutting through the main volume of the building.
