The general function of a stair is about helping people move down and up. Because of its inevitable functional need, we design stairs in a technical aspect mostly rather than designing stair by means of aesthetic form, speaking of which it hasn’t been further developed deeply integrated into architectural elements. Thus, in many cases our dedicated work toward stair is limited into counting numbers of steps and riser heights. Beside the fact mentioned above, it is quite lucky to have a chance for us to develop a stair in a residential environment. Now we deeply start to design the sitar with the idea from the form rather than function.
A Book is combined papers by its form. Each layer is fixed into one side and the other side is open end. When the book is bent 90 degree, it creates natural steps at open end, as if it would be possible to be designed into stair steps. By this initial ideas, we have developed the form of the stair that we call ‘Reel Stair”.
It is divided into two parts. One is fixed to the ceiling structure. The other to the floor slab. By its bent form, we have come up with wooden panel as an exterior material to be attached well to the structure frame. Mainly, we consider the three vertical metal plate cut to follow the steps. Those plates can be stabilized by metal frames connected each other. Finally each frame will support the form. Hence, we believe the form of stair is now created as to meet the functional need.
