There’s a physicality about Herbst baches. The buildings require their inhabitants to get up and do things – move shutters, open and close windows, take an outdoor shower, lug the food to an outside cooking area. And why not? For most of the year, most of us are estranged from physical activity. Machines do the moving for us. Bach life, as interpreted by the Herbsts, is an exercise in self-sufficiency, and an antidote to excess. If only we could pursue the sustainability of the summer encampment all year round.
