Spotted another tree placed on top of this steel frame building under construction on I-10 West.
The tree, usually a small pine, is of Greek origin. Mythology, To appease the forest gods that the wood used has not been killed (destroyed) that is if a tree god were to fly over the location he/she, it would see the “tree top” still alive. And the tree isn’t placed on the house after construction; it’s placed on the roof after the roof is papered,(weather tight) and removed after the home is CO’ed (recieved its’ Certificate of Occupancy)
