The two newest additions to the LEGO Architecture line are now available from LEGO Shop@Home: 21010 Robie House weighs in at a whopping 2,276 pieces and will set you back $199.99; 21011 Brandenburg Gate is a paltry 363 pieces and cost you $34.99.
That Robie House will be the first Architecture set I buy. I hope they make more sets of this size and scope.
