Nikolas Kichler studied architecture, and is fascinated by open design tools and urban issues. Together with his team he created the vivihouse, which got them nominated for the INDEX Award. Rapid urbanisation has led to environmental risks and limited citizen participation. With vivihouse, they make it possible for everyone to contribute to the creation of ecological and appealing urban living spaces. It is a modular building system designed for inclusion: It is DIY-friendly for makers and open source for designers. Residents will enjoy healthy and energy-efficient spaces while future generations can keep the resources in circular ecosystems. In 2018, they started with a single-story prototype. In October 2019, a three-story building will be presented to a larger urban population. With vivihouse they enable everyone to create healthy and vibrant urban settlements for themselves and all of us.
