The extension was designed to continue the dialog between flat and pitched roofs of the existing kindergarten with a two-story gable-roofed building and a two-story flat-roofed structure. It connects in the north-eastern part of the property which was designed by architect Gutweniger Willy in 1976. The aim of the extension was a holistic ecological construction method from the start, with the annex designed as a glue-free solid wood building with a wooden façade and green roofs. The solid wooden walls create a pleasant indoor climate due to their mass and texture. Another consideration was the spatial integration of the open learning landscape shared by German and Italian-speaking groups. The focus of the extension is on the encounter zones, opening up the possibility of togetherness, not only architecturally but also pedagogically.
