With the help of the catalog we produced, we specified the physical architectural elements (doors, windows, stairs, hallways, walls, floors, ceilings, ramps etc.) and settings which create some specific space experiences and/or relations such as enclosure, partition, access, orientation, transparency, light. Later, we produced a model which experiment the ish condition of such architectural elements. We used the the ish term to express the multipurpose of elements. In order to get used to the idea, you can analyze my studies below.
Sorry for the dirtiness, it was a working model.
