I went to see about 6 solar homes at the competition on Friday, when the weather was really really nice. The use of reclaimed something like reclaimed wood, barn, benches - anything that you can think of the second life of a material - is big. We come to an era where you'd see more and more the re-use of material for home constructions. Smart, sustainable kitchen countertops can be made of reuse, recycle materials like concrete, glass, newspaper, etc.
Here are some pictures from the competition.
