"The principle of waste architecture is designing and sketching with the materials and objects that are available," writes designer Boris Duijneveld, the founder of Netherlands-based MUD (Mobile Urban Design) Projects. "Playing with form, material and color leads to new insights and forms that cannot be imagined on a white sheet of paper."

That's an apt description of Culture Campsite, a campground located in a parking lot outside of Rotterdam, for which MUD was one of several firms hired to design some of the "tents." Instead of actual tents, however, Culture Campsite consists of nearly a dozen two-person sleeping structures made from repurposed materials and objects: Feed siloes, two calf shelters turned on their sides and connected at the bottom, a delivery van, a dumpster, and other ad hoc shelters.

Meals are served communally (and socially-distanced) inside a geodesic dome on the site, and the bathrooms are communal.

Though closed for the season, Culture Campsite is scheduled to re-open in May of 2021. Prices are €65-€75 (USD $76-$88) per night.
