This project is to expose students to ways of perceiving and recording the built environment through observation and investigation to enhance their design knowledge. We were asked to find a staircase and do all the measurement and figure out the details of the staircase we chose. The staircase that i have chosen is double L-shape staircase which the staircase in my hostel located at no.71 ss15/4a subang jaya. The reason that i chose this staircase is because i found that the design of this staircase is quite interesting, before doing this assignment, i didnt take much notice of this staircase but after doing this i realized that although the design looks simple but complicated after observed deeply.
