* Frame a partition wall with the alcove opening roughed in as a rectangle. Secure the frame so it is plumb and square to the ceiling joists, the adjacent wall studs (if possible),
and to the floor.
* Attach drywall to all surfaces of the framed partition wall except the bottom of the door header. Avoid creating a drywall seam on the king stud.
* Install corner beads and arches so the arch inserts will overlap the bead by 3⁄4". Typically, arches are secured with panel adhesive and screws.
* Tape, fill, and finish all seams, exposed fastener heads, and corners of the partition wall. Trim and finish the arched partition wall to match existing walls.
