4×8 Lean to Shed Plans

by Thomas

If you want to learn more about 4×8 lean to shed plans you have to take a close look over the free plans in the article. If you are a homeowner like me, you probably know how many items you need to clean and maintain the yard. therefore, I have designed this super simple and straight forward shed, so you can create additional storage space for a broom, a shovel, power tools and other items. Remember to read the local codes before starting the project and to comply with the local regulations. The codes differ from one area to another, so it is safer to read them thoroughly.

If you want to get the job done in a professional manner, we recommend you to plan everything with attention, as to prevent costly mistakes and to build a professional garden project. Invest in high quality materials, such as cedar, pine or redwood, as the bench will be exposed to all kinds of weather. Apply a few coats of paint over the components, to enhance their appearance and to protect them from bad weather.

STEP 1: Building the shed floor

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.

Fitting the skids

Fitting the skids

Also, 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.

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.  However, I recommend you to use pressure treated lumber for the floor frame, as the boards will be exposed to moisture.

Fitting the floor sheet

Fitting the floor sheet

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 frames

Side wall frames

The next step of the project is to build the side wall frames. 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.

Front wall frame

Front wall frame

Use 2×4 lumber for the front wall frame. Use 2×6 lumber for the double header. You can adjust the size of the door opening to suit your needs. Notice the double studs placed at both ends of the walls and the jack studs that support the double header.

Building the back wall frame

Building the back wall frame

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

 

STEP 3: Assembling the shed frame

Assembling the shed frame

Assembling the shed frame

Additionally, 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.

Top back wall frame

Top back wall frame

Frame the top back wall using 2×4 lumber. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs.

Remember that the height of this wall frame will directly influence the slope of the shed. Therefore, you need to adjust the height of this wall to suit your needs.

Fitting the top back wall

Fitting the top back wall

Fit the wall frame to the top of the back wall. Align the edges with attention, drill pilot holes through the bottom plate and insert 3 1/2″ screws to lock it into place.

 

STEP 4: Attaching the siding to the garden shed

Fitting the siding panels to the front

Fitting the siding panels to the front

Continue the project by attaching the 5/8″ T1-11 siding sheets to the front of the 4×8 garden 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. Makes sure the edges are flush around the door opening, otherwise you won’t be able to fit the doors into place.

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 5: Building the lean to shed roof

Building the rafters

Building the rafters

Next, you need to build the rafters from 2×4 lumber. Mark the cut lines on the beams and then get the job done with circular saw.

Fitting the rafters

Fitting the rafters

Fit the rafters to the top of the shed and place them every 16″ on center. Secure the rafters to the top plates with ties.

Side siding panels

Moreover, 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″.

Roof sheets

Roof sheets

Furthermore, 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.

 

STEP 6: Fitting the roof trims

Also, 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

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

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 7: Building the shed doors

Fitting the jambs

Fitting the jambs

Also, 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.

Building the doors

Building the 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

In addition, 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.

 

STEP 8: Finishing touches

Last but not least, you need to take care of the finishing touches. Apply a few coats of paint over the exterior of the shed. A little paint will get you far in terms of appearance, and it is a relatively small investment. If you need to store more items and this shed is too small for you, you could take a look over these 10×10 lean to shed plans.

You can add decorative trims to the shed to make it pop. Remember that you need to fit blockings between the rafters to seal the shed. In addition, add a vent to make sure the air circulates properly inside the shed.
