ArWeDe KLG is an architectural office based in Laufenburg (Switzerland). For professional reasons, we have been dealing with the topic of shelters and their special challenges for many years, as this topic is still of great importance in Switzerland.
In 2022, together with the Estonian company Revonia, we developed a unique shelter concept based on modular precast concrete elements that can be used to create shelters of practically any size and shape. All the parts for the systems come from the world’s leading manufacturers in Estonia, Finland and Switzerland. The concept and design are protected by EU law with European Union Intellectual Property Office certificate of registration nr: 015011978-0001
