To begin, we figured out how much space we wanted between the windows and the new fireplace. In our case, we wanted our fireplace to be 74″ wide (this will vary depending on your space and insert). We subtracted seven inches for the sides to be build out of 2x4s as well as 2 inches for the substrate and tile.
First, we cut two 2x4s down to 64″ long. Then we attached one board horizontally to the wall studs making sure it was level and was at the height that we wanted the mantel to sit on. Next, we attached the second board to the base of the wall making sure it was in line with the first board.

We had mounted our first 2x4s to the wall
Then, we used 2x4s to create two identical rectangles for the sides. We made sure that they were exactly the height of our mounted board. Also, we made sure that the fireplace insert had enough clearance per the instructions. Then, the rectangle boxes were attached to wall and the existing boards to create the sides.
The sides are just rectangles made out of 2x4s
We then built another square out of 2x4s to fit inbetween the sides as a front. Make sure it is square before attaching it.
You should have 3 boxes attached together to form the base frame.
Building the Upper Frame:
The homeowners wanted their fireplace to go all the way to the ceiling. So, we created another box using 2x4s making sure it was securely attached in the ceiling and to the wall studs.

Next, we added some extra supports to make hanging the television easy and solid.

Framing the Insert:
Finally, it was time to frame in the fireplace insert. Be sure to follow your instructions for your fireplace. We simply attached some 2x4s to create the width we needed. Next, we added cross pieces for the insert to sit on top of.
We added 2x4s to support the fireplace insert on all sides.
Building the Hearth:
We were able to use just one 2×12 to create the hearth. One piece was attached on each end and then the front piece was attached.
The hearth was constructed out of a 2×12
Once the framing was done, it was finally starting to look like a fireplace.

Finishing:
Now, the next steps really depend on what you want your finished fireplace to look like. At this point you could add shiplap, paneling, etc.
We had to add a backer board since we were using tile. Our particular tile allowed plywood as a substrate. Make sure to follow the recommendations for whichever product you use.
Plywood Wrapped Fireplace
Note: We did not wrap the hearth with plywood since the stone could adhere directly to the 2×12 frame.
We used a tile saw to cut the tile to the lengths we needed and used the caulk gun to apply the liquid mortar to the backs of the tile. This process was faster, cleaner and easier than having to use traditional mortar.
The stone tile going up
We sat an old barn beam on the base frame to create a mantle and the hearth top was some reclaimed barnwood that we sanded and stained. They were attached with glue and screws.

I love the transformation!!! I hope this gives you the confidence to try it too!
