Can you put an archway in a load-bearing wall?
Creating archways or openings in bearing walls can almost always be accomplished. ... If you decide to create a large opening in the wall, then the loads above the opening must be shifted to the sides of the opening using a properly sized beam.
How can you tell if a wall is load-bearing or non load-bearing?
To determine if a wall is a load-bearing one, Tom suggests going down to the basement or attic to see which way the joists run. If the wall is parallel to the joists, it's probably not load-bearing. If the wall is perpendicular, it's most likely load-bearing.
