Pieces of houses and buildings. I can’t bear to throw away cool old doors or windows, doorknobs, etc. It’s the definition of true architectural salvage. My source for these items are A. Contractors and home owners who give me cool old parts instead of throwing them away B. I harvest from my own home projects C. Second hand, i.e. Habitat for Humanity is one of my favorite places. These treasures can be amazing design aspects to put back in a house or re-purposed into furniture and artwork.
