  4. Pack the openings with compacted gravel and then arrange the blocks at their proper position.
  5. Ensure that each block is level.
  6. Build the floor using pressure-treated timber. Trim the inner 2?6 headers by about 3 inches as compared to the outer headers.
  7. Secure the 2x6s such that there is a 1.5-inch notch at both ends of each header joist.
  8. Trace out the joist hangers’ locations such they have 16 inches on center spacing and then fasten the hangers.
  9. Layout the floor frame over the concrete foundation blocks and verify that the frame is correctly square and completely level.
  10. Craft the 2?6 joists and secure them with the joist hangers using galvanized nails.
  11. Secure the 0.75-inch thick pressure-treated floor made of plywood to the floor frame with 2-inch wood screws.

Wall Frame

  1. The walls of the shed can be built on the shed floor before hoisting them into position.
  2. Frame the front wall using 2?4 studs spaced at 16 inches on center.
  3. The window header is made using a double layer of 2x6s, and the door header using 2x8s.
  4. Use 0.5-inch plywood spaces for creating the headers.
  5. Craft the studs, top plates, window studs, and blocking.
  6. For building the front wall, secure the corner trimmers with the corner studs using nails.
  7. Trace out the positions for the studs over the first top plate and the soleplate.

  13. Next, secure the blocking for the upper window in place using nails.
  14. Secure a long brace to the surface of the front wall diagonally so that the wall remains square.
  15. Fasten two 2?4 blocks to the front of the floor to bracing the front wall in position and prevent it from slipping as you hoist it.

  20. Like the front and back walls, craft the sidewalls on the shed floor and hoist them into place.
  21. Place a 2?4 at the rear wall location and then construct the side walls inside the space between the rear 2?4 and front wall.
  22. Using a friend’s help, hoist the sidewalls into place and fasten them to the front wall.

  3. Use your first rafter as a template for crafting the remaining rafters so that all of them will have similar cuts.
  4. Trace and cut one rafter using a 2?6 piece of lumber as shown in the diagram and verify that it fits correctly.
  5. Create and toenail the other rafters into place using galvanized nails.
  6. Build and secure the 2?4 blocking at the back and front.
  7. Secure metal anchors to the walls and rafters.
  8. Attach the leftover siding to the remaining sections of the shed.
  9. The sides will need 2 complete sheets with their upper boundaries centered over the 2?4 nailer.
  10. Now fasten Z flashing over these sheets using nails and then cut out the angular upper side sections to fit.
  11. Note to cut and extract the sole plate at the opening for the door.
  12. Carve the siding to fit among the windows and then secure the Z flashing over them. Then attach siding on the header above the windows.
  13. Cut out the door opening and retain the siding pieces for crafting the door later.

Fascia, Vents, and Roofing
