Classic example of a client wanting the tv mounted over the fireplace. Typically, the material above the fireplace is sheetrock with plaster and wooden studs behind it - pretty easy to mount a bracket and run cables behind. Once in awhile the surface is brick, which is much harder to install. This particular installation was stone - nearly impossible to find a flat surface. We didn’t want to start drilling holes in the rock, as it would permanently alter the fireplace, and what if the next owner didn’t want a tv over the fireplace?
The solution was to build a soffit with crown moulding. It gave us a solid mounting surface for a ceiling bracket, space to run wires, and a place for power. We provided the engineering, carpentry and design; the client provided the painter. There are a couple of photos here, highlighting the tv solution and the Bose in-wall speakers for the home theater system speakers. And check out the rear surround speakers - they look just like recessed lights.
