We love a good bottle of wine after a long day - especially one with a rich eco-historical pedigree like the vintages stored at the green-roofed Chateau Barde-Haut. Located in Saint-Emilion, which was designated a UNESCO World Heritage Site in 1999, and designed by Nadau Lavergne, the two minimalist Corten steel buildings have the same weathered look as the winery's existing stone buildings, but nothing of the wasteful energy consumption that un-insulated buildings of old often have. A green roof over the workshop provides insulation and filters rainwater runoff, and a small wind turbine provides outdoor lighting, rounding off the breezy, rustic ambience we expect from the south of France!
