This part is completely optional and mainly just for making the front of the construction looking nice. I think its worth the effort, as it adds a nice entrance to the storage spare under the oven for wood.
I made a template our of wood to support the brick arch while it is constructed and dries.
Arch in place supported on loose bricks, ready to start.
Lay bricks following the curve of the template you made.
All bricks laid for arch.
Wooden template removed, you can see I have started to fill the front with cut bricks to make the wall. I cut bricks with angle grinder and stone cutting wheel.
Almost bricked up
Bricks layed and cleaned up, I also cut a small bit of brick to make the middle a bit more attractive where bricks did not line up. You may of course be more acurate then me!
