In the mountain village of Pontresina, near the upscale resort of St Moritz, secondary residences now account for 58% of all housing. Long-time inhabitants are having to leave the valley, as they cannot find affordable housing. “We’ve just been turned down for another flat. It’s so discouraging. We've been looking for a new, affordable place to live for over a year now, but keep on drawing a blank,” says Marcel Schenk, a mountain guide in Pontresina, a village with just over 2,000 inhabitants in the canton of Graubünden, in eastern Switzerland.
