8×12 Lean To DIY Garden Shed Creation Plans With Floor & Wall Frame Blueprints
Clear any leaves or rocks from the area where you will be building the shed and drive 2×4 stakes into the ground at the four foundation corners.
Verify that the diagonal lengths are equal so that the floor is perfectly square.
Dig 6 inch deep ditches into the ground and fill it with gravel for holding the foundation blocks.
Compact the gravel and place 8×12 concrete footing blocks into the ditches.
Using a spirit level to check that each block is correctly level.
Use 2×6 pressure treated timber to craft the header joists.
Inner joists will be 3 inch shorter than outer ones.
Make a 1.5 inch notch on each header joist at both ends.
Assemble the floor joists with a separation of 16 inches between each other and then secure them with hangers.
Place the floor frame over the foundation blocks and check they are level and square.
Use galvanized nails to fasten the joist hangers.
Nail 3/4 inch thick plywood siding to the floor frame to finish building the shed floor.
Wall Framing
Craft the front walls of the shed by assembling 2×4 studs at a distance of 16 inches from each other.
Use two layers of 2×6 boards for crafting window header and 2×8 boards to craft the door header.

Nail the corner trimmers with corner studs for crafting the front wall.
Mark the location for attaching studs on the sole plate and first top plate.
Nail the next top plate over the first and secure the window cripple studs.
Fasten the top block with the short blocks.

Craft rear wall as shown in the layout diagram section of the shed building plans.
We will create a triple 2×4 end stud with small blocks.
Nail studs into the sole plate after marking their position and lastly fasten the upper plates.
Assemble side walls similarly, raise them into position and nail them to the front wall.
Lastly raise the back wall and nail it to side walls.
Constructing Roof Frame With Rafters
Install siding over wall frames before crafting roof frame because rafters will overhang the siding over the back wall.
Fasten three 4×8 siding sheets at top end of wall frame using 8d galvanized nails and keep an overhang of 3.5 inches.
Create one template rafter and use it as reference for crafting other rafters so that all cuts will be of equal depth.
Rafters are constructed from 2×6 timber as shown in the rafter template diagram part of the blueprints.
Assemble the rafters together using nails.
Craft and fasten the 2×4 blocking and then nail metal anchors to the rafters for attaching them to walls.
Two more sheets of siding will be needed to completely cover the shed.
Upper siding edge will remain centered on the 2×4 nailer.
Nail Z flashing onto the siding sheets and remove excess wood from the top edges for fitting it correctly.
Sole plate must be cut and removed for crafting the door opening.
Make cuts in siding and make it fit between the windows and after that nail Z flashing over them.

Now lay out asphalt singles over the roof starting at lower edge.
Install metal flashing to seal top of the roof and fold it over fascia.
Lastly attach a drip cap over the roof.
Assembling Doors & Windows
Craft the frames for windows 1/4 inch smaller that wall openings.
Carve out jambs and construct sill of required length.
Create a 15 degree bevel into the upper sill edge at 2.75 inches.
For side jambs you should mark the outline for carving rabbets on the sills and create 3/4 inch deep grooves.
Now make 3/8 inch deep grooves for rabbets on ends of head jamb.
Nail jambs with frame and then install window stops.
Secure mounting flanges and install window glazing.
Smoothen inner edges of windows so the can slide easily into the frame.
Seal the siding faces with water-proof sealant and fasten the window to frame using hinges.
Craft door jambs using 1×6 lumber.
Create rabbet grooves at a depth of 3/4 inch on the side jamb for connecting with top jamb.
Nail top jamb with side jamb and install stops near upper edge of jambs.
Fasten hinges over side jambs using screws.
Secure door frame to studs by installing shims and nailing through the shims.
Check that jambs are plumb and level with edge of siding.

Secure 1×4 door trim and then suspend the door on hinges.
Install door stops and attach barrel bolt for the door.
