FROM RELATIONLESSNESS TO RELATEDNESS: ALIENATION AND THE IN-BETWEEN REALM REVISITED
Özer, Tuğba; Alanyalı Aral, Ela; Department of Architecture (2022-9-16)
The transformation in the production processes and consequently in the urban form itself with the First Industrial Revolution has brought various forms of relationlessness, which have since been discussed as “alienation.” Alienation has manifested in the workplace, has permeated everyday life, has become concrete in the built environment, and has spread through screens; as a result, it has taken many forms through the ages. Even though these conditions that lead to alienation are still valid in the 21st cen...
