Don't worry, it wasn't a meteor shower or a falling tree. It is an intentional hole cut by my handy saw in the master bedroom ceiling. My buddy Matt came over to help on this one, and after we got everything measured out, we cut the hole and the joists in the ceiling. We then began framing in new headers on the joists that were cut. By that time it was getting late so we called it quits for the night.
When this is all said and done, there will be a prefabricated dome that will sit on top of this octagon. There will be lighting all the way around the octagon shining up on the dome. Originally I was going to have a circular opening, but after going to a concert at the Detroit Opera House, I liked the look of using an octagon. Here's a photo of the super elaborate ceiling.
