Stair used for viewing experience Stair used to look for someone Stair use not associated with view SURVEY ANALYSIS DIAGRAM Surveys were completed over a day and analysed the extent to which use of the stair related to view

STAIR USAGE GRAPH Stair usage over a 9 hour period was record and tabulate. The information was then used to generate a graph-like form in grasshopper that showed the most common floor to floor usage of the stair.
