Summary: Rich people spend $50,000 to deconstruct. Not so rich pay $10,000 to demolish.
Thanks, EPU. Now I get the gist of it.
You know, when I was in my early years in the trades, I worked for a contractor who did a lot of work restoring and customizing old homes in the Hollywood hills. In order to properly restore some of them, we had to track down original building materials that matched the old stuff.
Even then, there were outfits that specialized in stocking old original components from demolished houses. Most of that stuff cost an arm and a leg compared to their modern equivalents.
