With the project theme "LOST PLACES" in Urban Space, these areas were analyzed and documented in the context of the HTS according to their possible potentials beyond the prevailing value economy. The occupation with "the blind spot" within the urban building landscape should lead to a site-specific and interdisciplinary performance of light and sound.In their first approaches to the site, the students have been accompanied by a wide variety of moods and impressions. The spatial acoustic and visual reception differentiates the contextual experiences, which is important for the artistic, architectural work. The extremely different uses below and above the elevated road were also addressed - speed and standstill.
