Found this project on Salt & Water featuring a floating Hotel. The project is developed with the aim to promote tourism on inland waters that offer wonderful examples of untouched nature.
Maybe you can move the whole Hotel onto a different location like every year? Every apartment is a Catamaran on its own with a salon, gallery, bathroom, hall and sleeping area to accommodate 2-4 persons. I like this design a lot. I’m only very curious what a Catamaran apartment like this will cost?
