Soffit - Vaulted ceiling
Just moved into a house with a nice base for a home theater, but am thinking of building a soffit to house cables, recessed lighting, blacklight for star ceiling, etc. Building a soffit looks straight forward enough, but I can't find very much info on how it is connected when the ceiling is pitched.
Is there a way to do it without having a vertical attachment going into the ceiling structure? I am assuming if I don't go up into the ceiling, I will have to support it with either columns going to the floor or some kind of angled bracing going down the wall?
Thanks for any input. If this gets to be overly complicated I may scrap the soffit and stick with a more basic room.
