Build the west back wall (Blueprint B.01A) first using the shed floor as a surface. Cut 2x4x8s to size using a Battery Powered Handheld Circular Saw. Mark the top and bottom 2x4x12 plates using a Carpenter's Pencil and Measuring Tape and nail them together using a Battery Powered Nail Gun. Use a Hammer to finish driving any nails that stick out. Stand up the wall and nail spare 2x4s at about a 45 degree angle on either side to the end of the floor joists while leveling using a 4' Level.
Next stand up the north/south walls (Blueprint B.01B), and finally the other east/west wall (Blueprint B.01C).
Using a Battery-Powered Drill, drill through the bottom plates and into the floor joists using a 1/2" Drill Bit a few inches from the end of each cut and once in the center of the western wall. Insert a 1/2" x 4" Galvanized Hex Lag Screw with a 1/2" Washer into each hole and tighten using a 3/4" Ratchet Bit inserted into a Battery-Powered Impact Driver with a 1/4" Male Hex to 1/4" Square Drive Adapter. This will help keep the framing from pulling off in high-winds.

Walls must be capped with a second top plate, offset at least 24 inches at joints (IRC 602.3.2). Overlap the corners so they overlap the wall joints. Attach them by nailing Face Nail downwards stepping on a 8 ft Step Ladder.

The structure will be flexible when it's just studs. 3/8" Plywood sheathing adds shear strength. Confirm everything's level while installing the sheathing.
Hammer 3.5" nails lightly in between each panel. This will create an 1/8 inch gap between boards to allow for expansion and prevent buckling.
To find where to nail, drop a Plumb Bob Chalk Line from the top, lined up with each stud location, and pop a line.

2x6 Joists should just about line up with the wall studs, 16 inches on center IRC Table 802.4(1). Mark the end plates first, then prop up the joists over the ceiling span. Be careful not to stand in the shed while you do this in case the joists fall. Frame enough to form a box and toe nail the box into place. This should give you enough structure to add in the remaining joists.
IRC Table 602.3(1)No blocking is needed because the distance between the raised top plate and the top of the parallel rafter is 7 & 1/8". (IRC 602.10.6.2). The ends of each joist must touch the top plate for at least 1.5 inches (IRC 802.6). Use Post Frame Hangers to reinforce the opening the the ceiling.

Lay one 5/8" Plywood sheet up first and secure it to the joists enough to be able to get on top of it using a 24' Extension Ladder and finish fastening. Have one person pass sheets up while the other fastens.
For the access hole lay the sheet on before fastening and mark the edges of the hole from the bottom. Flip it over and measure out 3/4" from your line to increase the panel size and cut it out with the Battery Powered Handheld Circular Saw. To make it easier, nail the edges first, then run a Chalk Line across lined up with each Joist.

This is a good time to figure out how to cover the structure with a tarp so you are protected and can work towards prepping the framing for the roof. We tied a tarp down with 6 stakes and some rope.
Finish the 1x6s using the Shou Sugi Ban technique. Install them 3/4" out from the doorway so it will match up with the rain screen later.
Wearing proper attire, using a Propane Torch attached to a Propane Tank until the surface begins to char. Burn on a non-combustable surface such as asphalt or concrete. Have a Handhelp Weed Sprayer filled with water nearby incase anything ignites. Avoid plastic or loose hanging clothing. Once cool, coat the wood with an oil (we used tung oil) using a rag (rip up an old towel) and protective gloves. Let the oil dry before installing. Hang up used rags outside to dry before throwing them away. Don't store inside as rags soaked in tung oil can spontaneously combust.
You can measure and precut the boards before burning & oiling them or you can cut them afterwards and use a Butane Torch loaded using a Butane Canister to touch up the exposed areas.
Cut a roll of Flashing for the top and bottom of the doorway. Notch it so it can fold into place and overlap the edges. Place a board over it and hammer the board to shape the flashing. Install it using Roofing Nails.
Build the doors and insert them into place using Shims to create some spacing to make sure they fit and hold them in place. Insert the Hinges into the gap and mark where they should go on the jam and the door. also mark the hinge for distance it should extend out. Make sure the hinge pin extends past the jam so the doors can open 180 degrees.
This door installation will be temporary to make the shed lockable until you can finish the siding.
The easiest way to install the Deadbolt is to buy a Doorlock installation kit which will clamp to the door and provide the proper size hole saws.
Install 1x2x8s as a door stop trim on the inside of the doors to keep them from swinging through the frame.
Install 6 in Galvanized Barrel Bolts on the large doors. Two at the top center by the opening, and one at the center of the opening to connect the two doors.
Use two 2.5" Screws to install a small 3 inch door stop at the bottom to keep the doors from swinging to far at the bottom.
Install Felt Paper from the bottom up overlap horizontally 4 at least inches and vertically 2 inches. Use a Hammer Tacker loaded with T50 staples to get the paper up and hammer in Metal Cap Nails every 6 feet to keep the paper from blowing off. Install spare Felt Paper on the doors to protect them temporarily until the siding can be installed later.
