Interior Space and Exhibition Design FLOW LINE Office Building by Kris Lin The space on site is irregular and curve due to exterior wall of the building. Hence the designer applies the concept of flow lines in this case with the hope to create a sense of flow and finally converted into flowing lines. First, we demolished the exterior wall adjacent to the public corridor and apply three function areas, We used a flow line to circulate the three areas and the flow line is also the entrance to the outside. The company is divided into five departments, and we use five lines to represent them.
