E-Z Frame Yard Barn - 12'
Guide for construction of 12x12, 12x16, and 12x20 Yard Barn.
  1. General
    Prior to beginning construction, the area selected for the shed location must be leveled and cleared of obstructions.
  2. Inventory
    Separate all lumber, hardware, etc. into individual stacks of like items.
  3. Frame Preparation
    Figure 1 Unfold each frame, setting aside two frames to be used as end walls. From 1"x4" Pine boards, cut Gusset plates 6" long
    • 24 pieces for a 12' building
    • 32 pieces for a 16' building
    • 40 pieces for a 20' building
    Apply gusset plates on each side of the top and bottom fold locations. Frames to be used as end walls require only one gusset plate top and bottom on the side opposite of the metal plate, and to the inside of the building. Use four 8d nails on each plate. See Figure 1.
  4. Back Wall Framing
    Figure 2 Using one frame selected as an endwall, measure and mark stud locations according to dimensions shown in Figure 2. Place the proper length 2x4 studs at those locations. Mark required length and angles and cut to fit. Toe nail studs into place using (2) 8d nails top and bottom. See Figure 2. Cut 2x4 nailers and install at dimensions shown in Figure 2.
  5. Front Wall Framing
    Figure 3 Using the remaining endwall frame, repeat Step 4, using Figure 3 as a guide.
    NOTE: When using a roll-up door, the door opening must be framed to the exact size of the door. Example: 8x7 Roll-up door will have a finished opening of 96"x 84".
  6. Siding Back Wall
    Figure 4 Cut (2) 4'x8' sheets of siding into (4) 48"x48" pieces. Use 3 full 4'x8' sheets and 3 of the 48"x 48" pieces. Cut each piece as required. Nail siding pieces onto back wall frame with 8d nails every 8" on center. See Figure 4.
  7. Siding Front Wall
    Figure 5 Cut a 4'x8' sheet of siding into 2 pieces 48"x48". Cut another 4'x8' sheet into 2 pieces 24"x96". Cut each piece as required. Nail siding pieces onto front wall frame with 8d nails every 8" on center. See Figure 5.
    NOTE: (for steps 6 & 7) In order to keep moisture from wicking into the siding, keep the bottom of the siding 1" above the bottom of the treated bottom frame member.
  8. Framing
    Figure 6 From treated 2x4's, cut two rim joists:
    • 143" for a 12' building
    • 191" for a 16' building
    • 239" for a 20' building
    Place the cut rim joists 12' apart in the area selected for the barn location. Stand the front and back walls up at the proper ends of the rim joists. Nail rim joists to the end wall frames using 10d nails. Temporarily brace each end. Stand the remaining frames up:
    • 7 for a 12' building
    • 9 for a 16' building
    • 11 for a 20' building
    Nail to rim joists as shown in Figure 6. Install a temporary brace across low roof member. See Figure 6.
  9. Square the Building
    Figure 7 At base of building, measure across diagonally. Adjust the building until AC=BD. The building is then square.
  10. Floor Supports
    Figure 8 From treated 2x4's, cut (4) 21-1/4" floor supports and the required amount of 22- 1/2" floor supports
    • 8 for a 12' building
    • 12 for a 16' building
    • 16 for a 20' building
    Install using 10d nails, at dimensions shown in Figure 8.
  11. Floor Sheathing
    Figure 9
    • 12' Building: From two 4'x8' sheets of floor sheathing, cut 3 pieces 48"x47-1/2". Cut (3) 4'x8' sheets to 95-1/2" long.
    • 16' Building: Cut (6) 4'x8' sheets of floor sheathing to 95-1/2" long.
    • 20' Building: From (2) 4'x8' sheets of floor sheathing, cut 3 pieces 48"x47-1/2". Cut (3) 4'x8' sheets to 95-1/2" long. In addition to the cut pieces mentioned above, you will need 3 full uncut 4'x8' sheets.
    NOTE: Each piece must be notched on sides to fit around wall frame members as required. Stagger end joints front to back. Nail in place with 8d nails every 8" on center.
  12. Siding Side Wall
    • 12' Building: Cut (6) 4'x8' sheets of siding to 71" long.
    • 16' Building: Cut (8) 4'x8' sheets of siding to 71" long.
    • 20' Building: Cut (10) 4'x8' sheets of siding to 71" long.
    Make certain endwalls and frames are plumb (vertically level.) Then apply siding using 6d nails.
  13. Fascia Trim
    Nail 1"x6" to exposed ends of roof overhang using 8d nails. Top edge of fascia board should be 1/2" above the top of the roof frame member. This will cover the exposed edge of the roof sheathing.
