This paper presents a study on work‐unit types of advanced schools in Sweden. The results of this study are as follows. (1) A work‐unit is composed of 11 kinds of rooms and 2 kinds of partitions, clearly separated from the whole of a school building by partitions such as doors. As there are not many furniture in common spaces, a work‐unit can be located as the most important space for learning. (2) Several cases have “architectural outside spaces” related to units and entrances; this refers to a new external space on the site, filled with natural environment. In the other words, a school building is located as an element that invents an external space with the feature. (3) “Architectural outside spaces” are planned with many “attractors,” for example, benches, equipments, and play ground. (4) Common spaces are more important for higher grade students than lower grade students. However, outside environment is useful and important for lower grade students.
