In high school, one odd job I had was helping a family friend with his home construction. He had some unique ideas for his home, for sure. Very unconventional building techniques.
One day, we took a flatbed truck out to the local airpark. Evidently they had demolished a hangar recently. It dated back to the 1930's.
This friend took a massive attic support beam from the demolished hangar back to his house site and cut it to length to serve as the spine of his sub-floor. The support beam was a series of true-dimension 2x12 boards that had been laminated one upon the other with glue and nails to a final dimension of 14x12, IIRC. He cut out the very little bit of dryrot in the beam, patched it with an epoxy resin, then rigged a rather nifty floor leveling system to support this thing that allowed him to adjust the floor for level as the house or concrete foundation sagged over time.
The beam survived 60-odd years of eastern Washington weather, and then building demolition, to be reused as the spine of a new home that will stand for probably another 75-100 years. It's a beautiful home today, just across the street from my old High School, a creek running through the property, he's got a waterwheel that generates power off the creek. I know it's not quite laminate like being discussed here, but old wood getting reused has a sentimentality to it, and new laminate timber beams will end up being used 100 years from now by someone much like we reused that hangar rafter beam.
