The building is located on the southern square of Stora Saluhallen. Considering that Swedish people like to be outside in the sun between March and September, one concept of the design is to create a collective Sunlight roof. If you only consider the orientation, the sloped roof of the collective should face the south, but this will shade the north square. So I made a compromise here to orient the roof to the north. And the roof representing individual can be more freely facing north or south.
For indoor lighting, the collective space can open windows freely from the wall, while the individual space can open windows on the indoor wall in addition to the side high windows to obtain indirect lighting. This is the second compromise, through the collective and induvidual system The windows are overlapped to meet the needs of both.
