Don't just visit an architectural landmark—live in one. Santiago Calatrava, the man behind the 2004 Olympic Stadium in Athens, has designed residential towers in both Sweden and New York, opening this summer and in spring 2007, respectively. In the coastal town of Malmö, the 54-story Turning Torso, a spiral of concrete and steel modeled after the human form, will house 147 apartments with views of western Sweden and Denmark. Manhattan's 80 South Street, Calatrava's first American residential project, will rise 835 feet and resemble a staggered Jenga-style stack of glass-and-steel cubes. The four-story town houses will have garden terraces and 360-degree views. Both buildings will provide 24-hour concierge services and energy-efficient living. Studios in Malmö start at $1,026 per month (46-40/102-760;, while the New York condos run a cool $29 million (212/709-2633;
