Steinhäuser Straße, Karlsruhe · Bachelor application portfolio
A proposal for the redesign of the underpass on Steinhäuser Straße in Karlsruhe — a space that exists between infrastructure and city life, between transit and pause.
The project asks what an underpass can be when it stops merely serving movement and begins to hold it. The intervention works with light, section, and layered programme to transform a residual space into a threshold worth crossing.
Shown here as a physical model and as part of the architecture portfolio.
