Defenestrate

You create a window in a wall up to 45 feet away. The wall must be no thicker than 1 foot. Each creature of medium size or smaller in between you and the window must succeed on a dexterity saving throw or be thrown backwards by an invisible force through the window, in addition to suffering 1d6 Force damage. If a creature succeeds on a dexterity saving throw they take half damage and are not knocked backwards.

For every spell slot above 3rd level you cast Defenestrate at, increase the force damage by 1d6. If cast at 6th level or higher, the window will be big enough for a large creature to pass through. After one hour the window will disappear and the wall will return to normal.
