STEP 1: Building the shed floor

Building the floor frame

The first step of the project is to build the floor frame for the lean to shed. As you can see in the diagram, you need to cut the joists from 2×6 lumber. Lay the components on a level surface and align the edges flush. Drill pilot holes and insert 3 1/2″ screws to assemble the frame. Make sure the corners are square. Select the location for the lean to shed and remove the vegetation layer. Spread a 2-3″ layer of gravel under the shed floor, so you can protect the floor from moisture.

Fitting the skids

Next, lay the 4×4 skids under the floor frame and lock them together with rafter ties. The skids will lift the floor frame from the ground to protect the components from moisture. You can use 6×6 skids if you want to lift the floor frame more inches. Use pressure treated lumber for the floor frame, as the boards will be exposed to moisture.

Fitting the floor sheets

Fit the 3/4″ tongue and groove plywood sheets to the floor frame and align the edges flush. Leave no gaps between the sheets and secure them into place, every 8″ along the joists, using 1 5/8 screws. Invest in pressure treated plywood.

STEP 2: Building the shed frame

Side wall frame

The next step of the project is to build the plain side wall frame. Cut the components at the right dimensions and drill pilot holes through the plates. Insert 3 1/2″ screws to lock the plates to the studs. Make sure the corners are square.

Side wall with window frame

Use 2×4 lumber for the other side wall. Frame a 3’x3′ window so you can have enough light inside the shed. If you want just storage space, you can skip this step and build this wall identical with the opposite one. Notice the double 2×6 header and the jack studs.

Front wall frame

Frame the front wall for the 10×12 shed using 2x4s. Place the studs every 24″ on center and frame a 6′ opening for double doors. Use 2×6 lumber for the double header. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs.

Back wall frame

Build the back wall for the lean to shed, using the same techniques described above.

Assembling the frame of the shed

Fit the wall frames to the floor and plumb them with a spirit level. Drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor. Lock the adjacent walls together with 3 1/2″ screws. Make sure the corners are square.

STEP 3: Attaching the shed s >

Front wall siding sheets

Attach the 5/8″ T1-11 siding sheets to the front of the storage shed. Cut the sheets as shown in the plans and then secure them to the frame with 6d nails, every 8″ along the framing. Leave no gaps between the sheets and align them flush with the framing.

Back wall siding sheets

Attach the T1-11 siding sheets to the back of the shed frame. Align the edges flush and insert 6d nails to secure the sheets, every 8″ along the framing. Leave no gaps between the sheets for a professional result.

STEP 4: Building the lean to shed roof

Building the rafters

Next, you need to build the rafters from 2×4 lumber. You can use 2×6 beams if you live in an area with heavy precipitations. Mark the cut lines on the beams and then get the job done with circular saw.

Fitting the rafters

Fit the rafters to the top of the shed and place them every 24″ on center. Place the rafters every 16″ on center if you live in an area with heavy precipitations. Secure the rafters to the top plates with ties.

Side roof supports

Use 2×4 lumber for the side roof supports. Make the angle cuts to the top of the supports with a miter saw. Fit the supports to the shed and drill pocket holes at both ends. Insert 2 1/2″ screws to secure them into place tightly.

Side siding sheets

Fit the T1-11 siding sheets to the sides of the shed. Align the edges with attention and insert 6d nails to lock them to the framing, every 8″.

Fitting the roof sheets

Attach the 3/4″ plywood sheets to the roof of the shed. Start laying the sheets from the bottom up. Leave no gaps between the sheets and insert 1 5/8″ screws, every 8″ along the rafters.

Side roof trims

Fit the 2×6 trims to the sides of the shed. Align the edges with attention and insert 3 1/2″ screws to lock them into place tightly.

Front and back roof trims

Fit the 1×6 trims to the front and back roof of the shed. Use 3 1/2″ screws to secure the trims into place.

Fitting the roofing

In order to waterproof the shed, you have to cover the roofing sheets with felt. Make sure the strips of roofing felt overlap at least 2-3″ and staple them to the plywood sheets every 8″. Continue the project by installing the asphalt shingles. Place the starting course at the bottom of the roof, before fitting the rest of the shingles.

PRO TIP: Always read the manufacturer’s instructions, before installing the shingles. They provide essential information about the installation of the shingles.

STEP 5: Building the shed doors

Fitting the jambs

Fit the 2×4 jambs around the front opening. Align the edges with attention and insert 3 1/2″ screws to secure them into place tightly.

Double front doors

Next, you need to build the double doors for the lean to storage shed. Use 2×4 lumber for the frame and T1-11 siding sheets for the panels. After you cut the panels you need to lay them on a level surface. Lay the trims over the panels and then insert a few 1 5/8″ screws to lock them into place. Turn the door upside down and insert more 1 5/8″ screws through the panels into the trims.

Fitting the double doors

Fit the doors to the opening and then lock them to the jambs with hinges. Install a latch to keep the door closed and your possessions safe.

Fit the 36″x36″ window to the side wall opening and secure it into place properly. Afterwards, attach the 1×4 trims around the window to enhance the look of the shed.
