Demolition of the Servco building, located in downtown St. Louis MO. provided a large supply of reclaimed burnt wood. Located at 709 S. 1st Street, the fire at the warehouse was in December 2013. As you can see in the video, once the burnt edge is removed, the golden glow of the yellow pine is still there. These are approximately 200 years old, and a large quantity of boards and posts are available. Everything is de-nailed and milled to your preference.
