10×10 Lean to Shed Plans – DIY Slanted Shed

If you want to learn more about 10×10 lean to shed plans you have to take a close look over the free plans in the article. This garden shed has a square base and a roof with a 3 1/2:12 pitch. The storage shed features a door to the side with a generous window and double doors to the front, for an easy access inside. 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.

Made from this plan

STEP 1: Building the shed floor

floor-frame-for-10×10-shed

The first step of the project is to build the floor frame for the 10×10 garden 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. Place the joists every 16″ on center.

Fitting-the-skids

Select the location for large storage 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 and 1 1/2″ structural screws.

The skids will lift the floor frame from the ground to protect the components from moisture. 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 and you will thank me in 10 years.

STEP 2: Building the shed frame

side-wall-frame—plain-wall

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. Place the studs every 16″ on center. Notice the double studs placed at both ends of the wall frame.

Header

Side-wall-with-door-frame

Add a window opening and a door opening to the opposite side wall frame. As you can see in the diagram, you need to use double 2×4 headers and jack studs. Adjust the size of the opening to suit your needs.

To assemble the double header, join together two pieces of 2×4 lumber and a piece of 1/2″ plywood in the middle. Add glue to the joints and insert 2 1/2″ screws from both sides. The door opening is 36″x80″ so you can also install a prehung door,if you want.

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.

Back-wall-frame

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

Fitting-the-side-wall-frames

Assembling-the-shed-frame

Fit the wall frames to the floor of the 10×10 storage shed and plumb them with a spirit level. Align the bottom plates flush to the exterior edges of the shed floor. 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-wall-frame

Build the top back wall frame, using 2×4 lumber. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 16″ on center, as shown in the diagram. Make sure the corners are square and align the edges flush.

Fitting-the-top-wall-frame

The next step of the project is to attach the frame to the top of the back wall. Remember that you can easily add the frame to the front of the shed as well. It all depends on the direction of the lean to you want for your shed.

Align the edges flush, drill pilot holes through the bottom plate and insert 3 1/2″ screws to secure it to the wall frame.

STEP 3: Building the lean to shed roof

Rafters

Next, you need to build the rafters from 2×6 lumber. Mark the cut lines on the beams and then get the job done with circular saw.

Fitting-the-rafters-to-the-lean-to-shed

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 and 1 1/2″ structural screws.

front-wall-panels

Fit the 5/8″ T1-11 siding sheets to thefront of the shed. Align the edges with attention and insert 6d nails to lock them to the framing, every 8″.

Tall-side-wall-panels

Attach the siding sheets to the back wall of the shed.

side-wall-panels

Attach the siding sheets to the other side wall of the shed. Make cuts around the double door opening. Align the edges flush and insert 6″ nails to lock the panels into place tightly.

Fitting-he-purlins

Fit the 1×4 purlins to the top of the lean to shed. Place the purlins every 16″ on center, making sure you get 11 1/4″ overhangs on both sides. Drill pilot holes and insert 1 5/8″ screws to lock the purlins to the rafters tightly.

Front-wall-roof-trims

Fit the 1×8 trims to the sides of the roof. Align the edges flush and insert 2″ nails to lock them to the purlins.

Roof trims

Fit the 1×8 trims to the sides of the lean to roof. Align the edges and insert 2″ nails to secure them into place tightly.

fitting-the-metal-sheet-roofing

Install the metal roofing sheets to the top of the shed. Install 3/4″ roofing screws to secure the sheets to the purlins. Install drip edges, as well.

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

STEP 3: Building the shed doors

Side-door-jambs

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

Door-frame

Assembling-the-shed-doors

Next, you need to build the door for the lean to storage shed. Use 2×4 lumber for the frame and T1-11 siding sheets for the panels (the piece that you cut out when attaching the front wall panels). Cut the components for the door frame and drill pocket holes, as shown in the diagram. Align the edges flush and check if the corners are square. Insert 2 1/2″ screws to assemble the frame.

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-side-door

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

Fitting-the-window

Last but not least, you need to install the 32″x36″ window to the side wall. Next, attach the 1×4 trims around the window to enhance the look of the shed. Insert 2″ nails to secure the trims to the wall of the shed.

Double-door-jambs

Fit the 2×4 door jambs around the front double door opening.

Fitting-the-double-doors

Fit the doors to the front of the shed and lock them to the jambs with hinges. Install a latch to lock the doors closed.

This 10×10 lean to shed is easy to build and it will help you add valuable storage space to your property. This shed features a 3 1.2:12 pitch, but you can also make adjustments to suit your needs. This storage shed features a total height of 12 ft and a 10 ft x 10 ft base.

How-to-build-a-10×10-lean-to-shed

You can add decorative trims to the shed to make it pop. In addition, a few coats of paint over the exterior of the shed will get you far in terms of looks. 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.
