The architect’s main tool of representation, parallel projection drawing, can be described as the architect's way of "tracing the shadow of an imagined future". This shadow however, is bigger than the lines we put on paper. If we turn around and face the “behind” of the built, we find ourselves in front of a group of construction workers. “Parallel” and “shadow” are here no longer terms of architectural representation, but rather describes a shadow society existing in parallel to Swedish welfare. With the barracks conceived as infrastructure rather than homes, their inhabitants are being made invisible. Under the pretext "temporary", a lower standard of living is here excused. But workers tend to move from one temporary solution to the other, with the barrack and its shortcomings as a permanent backdrop to their lives.   This book is an effort to begin tracing the shadow of the architect's work, highlight the architecture indirectly produced, and begin a discussion on how to improve construction workers' living situation from an architectural  perspective.
