Pubdolls has created some great designs using legos. The modular shelving system is made of Lego window frames. Genius!
Mini Modern had suggested taking windows and doors from several Beach House by LEGO kits to build something in 1:12. The LEGO Architecture series might have some cool pieces to add to build a truly unique modern dollhouse. I'm adding this to my to do list, right after assembling the roof on my current house and building a few kits in storage.
I'm interested to see what else LEGO comes up with in their Architecture line. Right now they are focused on a new line of distinctive landmark building sets; John Hancock, Empire State Building, Seattle Space Needle. The plan is to "offer other famous landmarks throughout the world celebrating influential architects and movements that have shaped the environment around us." If this picture is an indicator of more modern design to come... yay!
