Built in my 55" TV above a corner fireplace....pics!
I had a 35" analog tube TV on a stand in my greatroom. It partially blocked 2 windows and had surround sound wiring going along the baseboards. To get the TV up off the floor and out of my way....so I could open ALL 8 of the windows and get the full solar heating value and see the view with no neighbors that we LOVE....we built the TV into a recessed area above the fireplace. It tilts, pulls out 20" and even can be turned sideways to view when in the adjoining kitchen....take a look. OH....and did I mention it used to be a rustic design, with a heavy wood mantle and is now a sleek modern design with a granite slab mantle. :0)
We did all the work ourselves. Cut off the raised hearth, gaining 20" of floor space, so we can now set the speakers on the new marble hearth. We love it!!!!!!!
The hearth matched the entryway tile. The grout was cracking because of the builders error, not installing hardibacker, insted..... installig ALL tile directly to the plywood base.
