Gehry wrapped the exterior with what appears to be scraps and rubbish. He used amount of cheap materials, such as plywood, corrugated metal, glass and chain link. As a result, the old house still exists inside the envelope of the new house.
This is a abstract model of the materiality.
I used sketch up to show how Frank Gehry use those cheap materials and change the original house into the amazing work. Make this house so powerful and energetic.
