Measure and Mark Perimeter
Use a tape measure to measure, mark and level the whole perimeter of the soffit.
Step 2

Measure 2x4s
Measure the first pieces of 2x4s to cut for the bottom ledger.
Step 3

Cut 2x4s
Transfer measurements to the 2x4s and make the appropriate cuts using a chop saw or circular saw.
Step 4

Install 2x4s
Install the 2x4s to the existing studs under the drywall using 2-1/2" wood screws and a screw gun. Attach them completely around the perimeter.
Step 5

Attach Parallel Supports
Measure, cut and attach the parallel supports to the walls by toe nailing them into the existing studs.
Step 6

Attach Cross Bracing
Measure, cut and attach the cross bracing to keep the frame firmly attached.
Step 7
Attach Top Plate
Measure and mark the top plate area. Lay the level perpendicular to the existing frame to determine where to attach the top plate.
Step 8

Cut Pieces for Uprights
Measure and cut the pieces for the uprights, which will keep the whole frame together.
Step 9

Attach Drywall Pieces
Once the whole frame is finished, measure and cut the drywall pieces and attach them with 2" drywall screws.
Step 10

Install Corner Bead
