This pavilion was erected to house the works of sculptor Knut Steen, in the grounds of the Midtåsen estate from 1933. The estate includes a terraced park with sculptures, old oak trees, pines and planting. The project includes new pathways, service roads and toilet facilities.
The pavilion is not climatized. The wedge-shaped plan opens towards the view and gives the art a neutral background. The materials are light concrete and glass, and the detailing demonstrates the freedom of an unheated structure.
