Best from last week, just in case you missed it. Alberto Kalach’s Atalaya House located in California, a house conceived as a series of terraces stepping down, is discovered step by step, revealing different atmospheres and different views into the distance, or to intimate gardens and patios. Don’t miss the amazing E+ Green Home by Unsangdong Architects or Ceip Martinet, a school in Barcelona designed by Mestura Arquitectes. Check out O-14, a 22-story tall commercial tower in Dubai by Reiser + Umemoto. Finally, watch the interesting AD interview with Renzo Piano (Part I-Part II-Part III).
