8×8 Barn Shed – Free DIY Plans

by Thomas

If you want to learn more about 8×8 barn shed plans you have to take a close look over the free plans in the article. I really wanted to add a new shed design for a structure with  gambrel roof to my blog, so you can have extra-store in your backyard. This is a basic small shed that is budget friendly, but also gives you a boost of style to your property. 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.

These DIY plans cover everything you need to know, starting with instructions, step by step diagrams, cut list, shopping list and a time estimate. If you like the barn roof design, this small storage shed will help you shelter tons of tools and garden equipment.

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---8x8-shed

Floor-frame—8×8-shed

The first step of the project is to build the floor frame for the 8×8 barn shed. Use 2×6 lumber for the joists. Cut the components at the dimensions shown in the diagram.

Also, lay everything on a level surface and align the edges flush. Drill pilot holes through the side joists and insert 3 1/2″ screws into the perpendicular components. Place the joists every 16″ on center and make sure the corners are square.

Fitting-the-skids---8x8-shed

Fitting-the-skids—8×8-shed

Select the location for large storage shed and remove the vegetation layer. However, spread a 2-3″ layer of gravel under the shed floor, so you can protect the floor from moisture.

Next, lay 4×4 skids under the shed floor frame, because you need something to lift the shed from the ground, and thus protect it from excessive moisture. Use 2 rafter ties and 1 1/2″ structural screws / nails to secure each skid to the floor frame.

Fitting-the-floor-sheets---barn-shed

Fitting-the-floor-sheets—barn-shed

In addition, 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. Consider buying Pressure Treated lumber for the skids, at least, if not for the floor frame, as well.

 

STEP 2: Building the shed frame

Side-wall-frames---8x8-garden-shed

Side-wall-frames—8×8-garden-shed

The next step of the project is to build the side wall frames, using 2x4s. 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.

I suggest you make sure the corners are square. Place the studs every 16″ on center. Notice the double to plate, that will add a lot of strength to the wall frame.

Front-wall-frame---8x8-shed

Front-wall-frame—8×8-shed

Furthermore, build the front wall from 2x4s. Notice the double header above the door opening. We need the double header to reinforce the wall frame. Therefore, glue two pieces of 75″ long 2×6 lumber to a 1/2″ plywood pieces at the middle.

Similarly, align the edges flush and add glue to the joints. Insert 2 1/2″ screws from both sides. You can adjust the size of the front opening, from 6 ft to something smaller.

Back-wall-frame---small-shed

Back-wall-frame—small-shed

Last but not least, you need to build the back wall frame. Notice that the frame is built from 2x4s, as the other frames. Cut everything at the right dimensions, as shown in the diagram. Also, measure the diagonals to make sure they are equal. If they are not equal, then your corners are not square.

 

STEP 3: Assembling the shed frame

Fitting-the-side-walls

Fitting-the-side-walls

Continue the project by lifting the side wall frames and lay them to the floor frame. Align the edges flush and plumb them  with a spirit level. Use temporarily braces to lock the walls into place, as shown in the 3D diagram. Drill pilot holes through the frames and insert 3 1/2″ screws to lock them into place tightly.

Next, fit the wall frames to the floor of the 8×8 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.

 

STEP 4: Building the gambrel shed roof

Building-the-trusses-for-the-barn-shed

Building-the-trusses-for-the-barn-shed

Next, we have to build the trusses for the barn shed. As you can see in the free shed plans, you need to make 22.5 degree cuts to both ends of the 2×4 rafters. Use a miter saw to make accurate and repetitive cuts.

Fitting-the-gussets

Fitting-the-gussets

Also, use 1/2″ plywood for the gussets. Follow the pattern in the image to build the gussets. Lay the rafters on a level surface and then attach the 1/2″ gussets over the joints. Drill pilot holes and insert 1 5/8″ screws to secure the gussets into place tightly. Remember to secure the gussets on both sides of the trusses, except for the trusses that go to the front and back of the roof (gussets on one side only, for these end trusses).

 

STEP 5: Fitting the trusses

Fitting-the-trusses-to-the-8x8-shed

Fitting-the-trusses-to-the-8×8-shed

Fit the trusses to the top of the 8×8 garden shed and plumb them with a spirit level. Use rafter ties and 1 1/2″ structural screws to lock the trusses to the wall frames. Place the trusses every 16″ on center.

Front-and-back-siding-sheets

Front-and-back-siding-sheets

Use T1-11 siding sheets for the front and back walls of the shed. Make cuts with a circular saw, so you can attach the panels into place. Leave no gaps between the sheets and insert 6d nails to lock them along the frame of the shed.

Fitting-the-side-siding-panels

Fitting-the-side-siding-panels

Attach the siding panels to the sides of the shed, as well. Use the same techniques described above to lock the siding panels into place .

Assembling-the-overhangs-for-the-barn

Assembling-the-overhangs-for-the-barn

Now, we have to assemble the overhangs for the shed, so we protect the front and back walls from the elements and so we can add more prestige to the construction project.

Use regular rafters and 2×4 blockings. Drill pilot holes through the rafters and insert 3 1/2″ screws into the blockings, as shown in the diagram.

Attaching-the-overhangs-to-the-barn-shed

Attaching-the-overhangs-to-the-barn-shed

Attach the overhangs to both ends of the barn shed. Align the edges flush, drill pilot holes through the overhangs and insert 3 1/2″ to lock them into place tightly.

Fitting-the-roof-panels---small-barn-shed

Fitting-the-roof-panels—small-barn-shed

Next, fit the 1/2″ plywood sheets to the top of the shed roof. Align the edges flush and insert 1 5/8″ screws along the rafters, to lock them into place tightly.

Gambrel-end-roof-trims

Gambrel-end-roof-trims

Use 1×6 lumber for the gambrel end trims.  Moreover, use a miter saw to make the 22.5 degree cuts to both ends of the trims and then lock them into place with 6d nails.

 

STEP 6: Building the shed doors

Door-frame-for-shed

Door-frame-for-shed

You need to use 2×4 lumber for the door frame. Cut everything at the right dimensions shown in the diagram. Drill pocket holes at both ends of the vertical and middle components.

Next, lay the components on a level surface and leave no gaps between them. Align the edges flush and make sure the corners are square. Insert 2 1/2″ screws to lock the frame together tightly.

Assembling-the-shed-double-doors

Assembling-the-shed-double-doors

Also, attach the T1-11 siding panels that you cut out in the previous steps to the back of the door frame. I recommend you to add glue to the joints and make sure the edges are flush. In addition, insert 2″ nails to lock the panel into place tightly.

Fitting-the-door-jambs---8x8-shed

Fitting-the-door-jambs—8×8-shed

Fit the 2×4 jambs around the door opening. Align the edges flush, drill pilot holes and insert 3 1/2″ screws to lock them to the shed.

Fitting-the-double-doors

Fitting-the-double-doors

I recommend you to fit the double doors to the front opening and then lock them to the jambs with hinges. Install a latch, so you can lock the doors into place tightly.

 

STEP 7: Finishing touches

You can add 1×4 decorative trims to the shed to make it pop.

8x8-barn-shed-plans

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.
