Kjellgren Kaminsky Architecture’s extension to Kollastaden School, situated in the Centre of Kungsbacka, is one of the largest Passive House buildings in Sweden. The building is strategically placed to envelope a communal schoolyard between the new and the old, providing a playful, inspiring and sustainable school environment centered around the students. There is parking for both cars and bicycles and zones for the school taxi and the schoolyard is used for activities that support learning. The building has a compact shape to make it more energy efficient, and the school interior combines open spaces with a calm atmosphere.
On the north side of the school a communal schoolyard connects the new and the old buildings. It was designed to be actively used by students participating in activities that support learning.
The street facades made of pale brick are kept relatively restrained and establish a close dialogue with the surrounding areas, while the facades facing the schoolyard are clad with fiber cement boards that create a more colorful and playful expression both in design and in volume.
