Picture the scene. Among sand dunes, gnarled shrubs and prickly palm trees, a city rises from Arizona's Sonoran Desert - no, we're not describing the set of Dune. The brainchild of the late Italian architect Paolo Soleri, the concept, dreamed up in the 1970s, was simple: to build a city that comprises both environmental and design-driven factors, while offering an efficient and go-slow lifestyle for inhabitants. Ribbed and rounded, sweeping and smooth, each of its otherworldly structures are angled toward the south in order to maximise light and heat. With no roads and a population that hovers around 100 people, this unique and beguiling complex makes for a proper off-grid escape - and some incredible photo opportunities.
Why it should be on your radar: An experimental town built in the middle of the Arizona desert? Reason enough for us.
