I would like to construct an arched entry into my dining area. Currently, there is a 70” wide x 4.5” deep x 8’ high opening between two walls; ceiling is 8’ high. I think it needs a 1’ head wall at the top of the arch. Any suggestions on how to construct a frame, arch, and cover it with drywall and mud?

If you go to page 3 of this interior home impr. Section, 6th post down, it is explained how to build an arched opening. Post back if you have further questions about building the arches.

Would like to build an arch between kitchen and family room. How do I shape the construction material to fit?
