I'm looking to build a wall to wall closet in an existing drywalled space. The length of the wall is 82" and I am planning on adding a double door with 28" doors.
1. Ceiling joists run parallel to the wall and the wall will have to be between two existing joists. No choice on placement here.
2. Ceiling is not flat. On the left side the height is a normal 8ft ceiling. On the right side, (against an exterior wall) the height is 84". From the right side the ceiling slopes upward for 4.5 feet until it is 8ft high and then curves and runs flat and level to the left (interior) wall.
3. No attic access to ceiling. (Above existing drywall is vapour barrier and insulation)
My proposed solution:
Since there is no ceiling joist, but I have a solid wall on either side
to fasten studs to - I planned to forego the usual "king stud" door framing and have the door header run the entire length of the wall and frame the door opening and rest of the wall below it.
I would then install this portion of the wall first. Then built up the portions above the door header after installation. I would fasten the top plate to the ceiling with construction adhesive and drywall toggles. The cripples will then be cut to length on an angle for each location.
Problem with this approach:
The sloped ceiling and wall height on the exterior (right) side will not allow for a substantial header to run the entire width. With only 84" height available at the right wall, I only have a couple of inches above the space required for the frame.
Will a single 2x4 be sufficient to serve as a door header for this (approx 60" opening) closet door?
Is there a better approach?
