Here's how its looked for the last couple weeks. All the metal framing is in place as well as the ductwork.
Here's the start of the raised hearth. Those are 2x6's, so when the hearth is complete and tiled, it will be about 7-1/2" tall.
The dogs quickly found their new favorite spot, nice and warm...
Cutting the 1/2" thick, fireproof cement board with a diamond blade. This will line the walls and the hearth. Yes, if you look closely its snowing outside. Where's our nice spring weather?
Here is the hearth with 2 layers of Durock to offer extra protection from the heat. Also the first sections going up on the walls. The next pieces I will need to cut to follow the curves of the top of the fireplace.
