A mountain-biking vacation is usually a rugged adventure—with similarly rugged sleeping accommodations—but soon you may have the option of leaving the tent at home. That is what Philip Modest Schambelan and Anton Fromm are proposing with their concept hotel, Hiding in Triangles. If realized, the futuristic design would be perched 500 metres over the northern tip of Lake Garda in Italy, a popular mountain-biking area. Entirely bike-in/bike-out, every level and most entrances would be accessible by angled ramps and connected conveniently to the network of biking trails in the area. The hotel would have a panoramic view to die for—those prone to vertigo might want to give this one a miss.
