The best pieces of architecture are the ones that surprise us. Playing with perspective and color, the Lucky Knot bridge stands over Changsha’s Meixi Lake district. Designed by Beijing and Amsterdam studio NEXT Architects, the bridge is weird and unexpected, not necessarily beautiful, but playful and light-hearted. We imagine this is the sort of place where you’d meet a long lost lover, one of those odd situations where you mail someone you used to know a postcard telling them to meet you at the most obscure location in the world. Can’t you just see it now?
