A freestanding luxury villa in Tegernsee, Germany, designed by renowned Italian architect Matteo Thun. As the last rays of sunlight fell on the new low-rise buildings on the west side of Tegernsee, there was a whiff of sulfur in the air, and the surrounding metal bars glowed at the building's upper and lower edges. Just a few hundred metres from the lakeside, on the flat shore, overlooking the metre-high reeds on the opposite side of the so-called Gold Coast, which has longer hours of sun at night.
