Exploring nature and landscapes is a strong tourism trend, as well as spending the nights in unusual places. The off-grid Cabiner hiking cabins offer an inspiring new approach towards overnight stays. Following the idea of a fully self-sustained circular design, the cabins use cardboard as their main building material. They are based on a groundbreaking construction technique that involves an innovative rotating mould tool to generate the house-shaped structure. The structure consists of a total of 24 layers that are bonded together using environmentally friendly glue. The result is a robust sandwich structure with optimal insulation properties. Moreover, the processed cardboard also has a delightful aesthetic appeal and possesses exceptional constructive strength. The cabins are placed in Dutch national parks and are only accessible by foot for nature lovers who want to enjoy a night in the wilderness. The interiors are designed to offer visitors a comfortable stay with access to clean drinking water, a hot shower and a non-odorous flushing toilet. With the aim of ensuring efficient energy consumption, the system runs on a photovoltaic cell and a manually operated water pump. Thus, the ground water is filtered and pressurised. Heating is achieved with a wood-fired stove, while an innovative exchanger serves to heat the water and ensures that there is no temperature overflow and no legionella risk.
