Camping trailers continue to be popular, and not just in Europe. However, they do provide very little living space. Jakub Novák has proposed an innovative solution, allowing you to expand your trailer after parking it, and to use it for a larger number of people. The designer achieved this through a special sliding mechanism, which he managed to introduce without affecting the attractive external shape of the trailer. This work was presented at the 22nd International Design Biennial in Ljubljana.
