The extension of the Winterthur Museum of Art, built as a low-cost construction, creates additional space for the next decades. The extension also had to include a car park. The new building simply consists of a parallelepiped attached to the rear of the city art gallery. A covered passageway connects the new extension to the neoclassical main building designed by Rittmeyer & Furrer in 1915. The exhibition rooms are rectangular spaces with a sawtooth oriented to the north. An objective of the design was to create exhibition spaces which shouldn't compete with the works of art. A simple grid is used to divide 1000 m² of space into different rooms of varying sizes and proportions. Walking from room to room, the visitor enters them from different angles and experiences their dimensions in different ways. Three large windows allow visitors to look out and give sense of direction. The building is built as a galvanized perforated box; the façades are covered by u-glass, placed vertically.
