This thesis explores the possibilities of in-between spaces bounded by the realms of public and private experience in an urban environment, specifically situated in Downtown Providence, RI. This thesis begins by questioning the meaning of what public space is and how we as humans choose to inhabit space that has been given a particular program or quality. What allows a person to feel that he or she has ownership over a public space? Through the interdisciplinary lens of Landscape Architecture and Interior Architecture, the subsequent phases will analyze how people in Downtown Providence perceive and utilize space within the city and how the city could be reimagined by activating interstitial spaces. What constitutes public space and how ownership can be attributed to a public space is vital to understanding the characteristics and life involved in in-between spaces such as alleyways.
