Frank Lloyd Wright's Falling Water built entirely from LEGO Bricks. The toys have been around since the 40s so it's seemed inevitable that someone would eventually create a life size version of the building blocks. Those years of building as a kid can now be put to good use as that time has finally come.
Ecomat recently released their industrial sized building blocks which are made from 100% recycled materials. These blocks are lightweight, earthquake resistant and can be used to build both permanent and temporary structures. And since the construction requires no mortar, the building time is much quicker compared to traditional methods. They also provide good thermal and acoustic insulation. While we can't imagine building our own house out of these bricks, they could have endless applications in developing worlds and emergency housing situations. Since they are so lightweight, their shipping footprint is significantly less. To learn more about Ecomat's building bricks, visit Inhabitat or you can visit Ecomat's site (if you can read Italian).
