One of the many lessons of custom home building. If you don’t like the way an installation is progressing, act decisively as early as you can and change it. This is particularly true when translating drawings into a three dimensional structure from a computer screen.  It is always easier to step in and change something sooner than leaving it and having to tear something out and cause other collatoral damage with a late stage correction.  

Earlier fireplace framing wasn’t to our liking. Version 2 is better.
