Contemporary urban development seems to, globally and simultaneously, aim for the same results; densification, connections and an active urban life. In Stockholm this is emphasized through the comprehensive plan, The Walkable City. This thesis aims to research the com- plexities of open space, in-between areas and cultural practices on borders of territories. I have visited two neighborhoods, one in Stureby, Stockholm and one in Madison, Wisconsin as part of an art-based research where places for cultural practices have been observed and performed by me as a way to investigate in-between areas and what role they take in everyday lives. I have met with inhabitants for observations and interviews as well as performing an everyday life of my own when staying in Madison for two weeks. I have used a few different pictures of neighborliness to see what exists between the frame of the pictures and the situation, and related this to Miwon Kwon’s notion about places situated next to each other. I have also looked into the concept of territory, the ambiguous space between them and the communication that occurs on interfaces. In Stockholm's comprehensive plan and the research of Alexander Ståhle, I see an aiming for densification through connections, e.g. in walkability. I emphasize on a difference between connections and communication. With this thesis I suggest to change the topic of a planning discussion going on in Stockholm as well as globally, from how to create walkability to how to make use of interfaces of ambiguous open space when densifying cities.
