With a lot of fireplaces, they need to create an escape for the heat to vent out. To do this they leave a gap at the top of the fireplace wall to create a crown to hide the opening. A gap is not necessary.

Your wall will not have any intake or exhaust louvres to break up the look.

There are no vents required behind the wall of the fireplace to dump the built-up heat.

Everything is contained within the firebox. Able to finish with combustibles around the fireplace. No special concrete board or metal studs
