He goes on to talk about proxemics, the interrelation of observations and theories of the use of a space. There are three different levels of this, dealing with the past, present, and future to say the least. With this in mind, it should be understood that the boundaries of a territory remain constant, as do the locations within the territory. These territories are marked by visual, vocal, and olfactory signs.
One of two points Hall hits includes a FIXED-FEATURE SPACE. This simply means activities are organized around individuals and groups. A funny fact that's mentioned to go along with this is that "messy" or unorganized people don't typically classify a specific room for a certain activity. Moods will also change as the set up does. These changing architectural aspects allow a person to be who they truly are because they no longer have to hide.
The last point Hall touches on is that of sociofugal (parting people) versus sociopetal (bring people together). In many commercial buildings' waiting rooms, chairs are set up in such a way that doesn't allow optimal conversation. Osmond figures out that this is because of the layout (most are set up "military style"). According to Osmond, corner conversations are ranked number one, followed by face to face conversations and side by side conversations.
Ultimately, all a space really needs to have is flexibility and congruence between design and function to offer a variety of spaces.
