"Existence in a one-room apartment is nothing other than the being-in-the-world of one single case"
This term can be defined as space driven by the individualistic ego within the coisolated environment. Peter Sloterdijk sites the private apartment as an "atomic or elementary egospheric form - as a cellular world bubble." Our apartments or houses allow us to control every aspect of that space, making these spaces a direct representation of us. In the urban environment the egoshpere is housed under organically emerging structures, which causes the coisolated environment Sloterdijk refers to in his readings to exist and flourish.
