The scale is an important issue for architects, for understanding scale issue we worked on a unit ‘BED’ with two operations multiplicity and resize we worked on the bed issue. Firstly, I focus on bed and its definition, a private horizontal simple surface can be a bed like a yoga mat. I multiplied bed juxtaposed and with borders. Then I placed beds in urban contexts, with multiplicity its privacy changed also in an urban context is it a still bed? Now it is a just horizontal surface for any aim. Then I scaled beds, especially I preferred a bed that has storage so when the bed was scaled storage as well. Then I analyzed in a different manner, the bed is a horizontal surface but when we extrude this surface there were also four vertical different surfaces. These surfaces also can be used.
