The rise of the Instagram-idealised #vanlife movement has been good news for Airstream. As more millennials opt out of urban office-dom for life on the road, sales of the 90-year-old, bullet-shaped trailers have soared 218 per cent in five years. More compact, tech-enhanced new models have helped. But so has the rise of work-anywhere digital nomadry: as San Francisco-based architect’s Edmond + Lee has shown with its retrofitted 1960s Airstream Bambi II (pictured), they make great on-the-go offices. The trend has also infiltrated travel: Airbnb reports that Airstreams are some of its most sought-after bookings while Autocamp has just opened its third (and largest) Californian Airstream “campsite” to date, at Yosemite National Park.
