Plastic waste in the seas and rivers is a worldwide phenomenon. An accompanying workshop and exhibition addresses the topic of "pollution of the seas through plastic" and experiments with the use of the wastewater as construction material for innovative low-cost buildings.

The sustainable use of resources, the reduction and reuse has become one of the most important topics worldwide. With this project - a cooperation between Bavaria and Western Cape - innovative possibilities will be presented at one of the global hotspots.

At the same time the installation takes on the topics of low-cost, urbanization and environment. As an eye-catcher it also illustrates new building techniques for low-cost construction by the way recycling material is used. The building wants to be a symbol of how our resources are being used. On the one hand it provides opportunity to experiment with architecture, low-cost material and plants. On the other hand its purpose is to promote ecological awareness. The house is a design object and wants to include technical innovations and architectural features.

Worldwide there are more than 100 million people homeless and more than a billion live in bad accommodations. At least 600 million people live in accommodations which are perilous or harmful to health. These numbers are bound to elevate because of climate change, environmental disasters and trouble spots in general. Therefore the idea is to use cheap or cost-free waste like recycling material for innovative, attractive and eco-friendly low-cost accommodations / buildings. Instead of burying or burning the materials after floods, earthquakes or storms, a cycle with reusable raw material is started.
