Brandenburg’s Alhambra

Brainstorming and planning workshop

The objective of the planning workshop is a loam building that protects people, landscape and nature and combines innovative and economical process technology with contemporary design language. With a planned length of about 4.2 km, the largest contemporary earthen building ensemble in Europe would be created. This would have the potential to help loam as a building material of the future achieve an economically relevant breakthrough.
In a cooperative planning workshop, the layout of the freeway service area planned near Nebelin will be investigated and designed with surrounding earthen noise barriers and landscapes. This structural fabric is to become a pioneer for a coexistence of new technology and sustainable planning and building.
The concern of the workshop is to design the guiding structures of the facility for people and protected species in such a way that a coexistence of innovation in construction, noise protection, nature protection and nature experience succeeds.

The ends of the clay noise barrier with zigzag termination. This fulfills several functions at once: static – increasing stability against wind pressure; ecological – more diverse habitat due to the formation of niches and sunlight at different angles; aesthetic – breaking up the monotony and interesting shape.
