Stair in Erimtan Museum

One other part of the first assignment was studying one of the stairs in Erimtan Museum, focusing on the details and taking the exact measurements. The stair in the library was our model. This stair is a very unique one and it is not a stair we usually claim. Imagine two same stairs with very high steps. One of the stair is shifted average of half a step up and then intersected one within the other. Intersecting one within the other helps humans to move more comfortably and ensures safetiness  by producing variations of different heights. If that intersecting process wasn’t done, claiming all the way up, or exact opposite claiming all the way down, would be very hard and given more effort and energy would be a necessity. Therefore, this feature of the stair is very special.


Layering method was used for abstracting the stairs. By this approach, the middle part was emphasized more strongly and we especially did it this way, because as I mentioned before, the middle section was used more often and, the movement and the speed was restricted at the sides and not dense enough when compared with the middle.

So, let’s talk more about the stair and the surrounding area. That space which is left for the employees of the museum, is very small. Even it was very narrow, the stair didn’t loss its function; because it was designed very good. I want to point to the angle of the stair: The reason behind using angular vertical surface is to fit as much steps between that two-floor  with out interrupting human movement.


This is Nilay. She was exploring the stairs. As we all, she also had difficulties while claiming the stairs.

Because we had a very short time to explore the library and especially the stair, we talked with the employees. They also told us that, at the beginning it was very hard for them to get used to it, but after a while they started claiming the stairs without watching their each step. We also did try claiming the stairs. I think, in such a design like this one, the middle part, where the two stairs intersect, is a great idea for preserving human foot scale and facilitating human movement without inhibiting the design.

Also, after the discussion in class, I did some sketches related to the movement of humans.


Sitting on the steps was one of  the action which can be achieved on the sides of these stairs because of the major height difference.  The function of the middle part ease the human movement: claiming. The location of the stairs helped to view the library and observe one floor below.  These all were achieved because of the dimensions of the stair.
