STEP 1: Building the 10×12 shed floor

Building-the-floor-frame—10×12-shed

First step of the outdoor project is to build the floor frame for the garden shed. Cut the components at the right dimensions from 2×6 lumber. Lay the joists on a level surface. Drill pilot holes through the long joists and insert 3 1/2″ screws into the regular joists. Place the joists every 16″ on center. Measure the diagonals and check if the corners are square.

Fitting-the-skids—10×12-outdoor-shed

Fit the 4×4 skids under the floor frame, so you can lift it from the ground and protect the components from the moisture. Use rafter ties and 1 1/2″ structural screws to secure the skids to the floor frame. Invest in pressure treated lumber for the skids.

Select the location for the shed and remove the vegetation layer. Level the surface thoroughly and them compact a 4″ layer of gravel. This will help you by keeping the moisture away from the floor frame.

Floor-sheets—small-backyard-shed

Use 3/4″ pressure treated plywood for the floor of the shed. Cut the sheets at the right dimensions and lay them to the frame. Align the edges, leave no gaps between the sheets and insert 1 5/8″ screws to lock them into place. Insert the screws every 8″ along the framing joists.

STEP 2: Building the 10×12 shed frame

Side-shed-wall-plans

Next, we need to assemble the plain side wall frame. Cut all the components from 2×4 lumber. Lay the components on the shed floor and attach the studs to the plates, every 16″ on center. Use 3 1/2″ nails or screws, through the plates into the studs. If you use screws, drill pilot holes. Notice the double studs placed at both ends, with 1/2″ plywood blockers between them. Double check if the diagonals of the frame are equal before laying it to the shed floor.

Side-wall-with-window-and-door-frame

Next, assemble the other side wall for the shed. Use the same techniques described above. Notice the window and the door openings, with the double studs and the double 2×6 headers. Use 2x4s for the window headers. You can adjust the location and the size of the openings to suit your needs.

Header

To assemble the double header, join together two pieces of 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.

Front-wall-frame

Next, build the front wall for the garden shed. As you can see in the diagram, I have designed it with a 6 ft opening, so you can install double doors and have easy access inside the shed with larger objects. Notice the 2×6 double header. Measure the diagonals of the wall frame and make sure they are equal. In addition, check if the corners are square when installing the studs. If you need more space for the opening, you can go as large as 8 ft, with very little modifications.

Back-wall-frame—garden-shed

Next, build the back wall frame for the shed. Cut the components at the right dimensions and lay them on the floor of the shed. Use 3 1/2″ nails / screws to secure the studs to the plates. Notice the double top plates.

Assembling-the-frame-of-the-garden-shed

Lay the side walls to the floor of the shed. Align the edges flush and use a spirit level to plumb the side walls. Use temporarily braces to secure the side walls into place. Use 3 1/2″ nails or screws to secure the walls frames to the floor. Insert the nails / screws through the bottom plates.

Next, attach the front and back wall frames to the floor of the shed. Make sure the edges are flush and then insert the 3 1/2″ screws through the plates into the shed floor. Lock the adjacent wall frames together with 3 1/2″ screws. Insert 3 1/2″ screws through the top plates.

STEP 3: Building the gable shed roof

Rafters-for-10×12-shed

Next, build rafters for the shed, using 2×4 lumber. Use a miter saw to make the angle cuts, that is the quickest and most accurate method to speed up the process.  The 26.5 degree roof slope is equivalent to a 6:12 pitch.

Middle-truss-support

Lay the components on a level surface and align the edges flush. Cut and fit the middle support to the trusses.

Gussets

Use 1/2″ plywood for the gussets. Mark the cut lines on the plywood and get the job done with a circular saw. Lay the gussets over the joints, as shown in the diagram. Use 1 5/8″ screws to secure the gussets into place. The gussets will reinforce the trusses, but remember to attach them to both sides of the trusses, except for the front and back end trusses (only on one side).

Fitting-the-trusses—storage-shed

Attach the trusses to the top of the shed frame. Plumb the trusses with a spirit level and lock them to the top plates of the side walls with rafter ties and 1 1/2″ structural screws. Place the trusses every 16″ on center.

Front-wall-siding-panels

Use 5/8″ T1-11 siding sheets for the exterior of the shed. Align the edges flush to the side walls of the shed, then insert 6d nails, every 8″ along the framing. Use a saw to make the cut outs for the double door opening.

Gable-end-panels

Cut and attach the siding panels for the gable ends. Use 6d nails to secure the panels into place, every 8″ along the framing.

Side-wall-with-door-panels

Fit the T1-11 siding sheets to the side of the shed. Notice the cut outs around the door and the window. You can perform the cuts with a circular saw.

Back-wall-siding-sheets

Fit the T1-11 siding sheets to the other side of the shed.

Assembling-the-overhangs

Build the overhangs for the front and back of the shed from 2×4 rafters and 2×4 blockings. You can adjust the size of the overhangs to suit your needs. Drill pilot holes through the rafters and insert 3 1/2″ screws into the blockings. In this case, the blockings are 8 1/2″ long, so we get 10″ wide overhangs.

Fitting-the-overhangs—10×12-gable-shed

Fit the overhangs to the front and back of the shed, as shown in the diagram. Align the edges flush, drill pilot holes and insert 3 1/2″ screws to lock them into place.

Fitting-the-roof-sheets—-backyard-shed

Use 1/2″ plywood sheets for the roof of the shed. Cut the sheets as shown in the diagram and then lay them to the roof structure. Leave no gaps between the sheets, drill pilot holes and insert 1 5/8″ screws, every 8″ along the trusses.

Fitting-the-side-roof-trims

Front-and-back-roof-trims

Use 1×6 lumber for the front , back and side roof trims. Fit the trims to the sides of the shed and lock them into place with 2″ nails. Use a miter saw to make the angle cuts at both ends of the trims and then secure them into place with 2″ finish nails.

Fitting-the-roofing—10×12-garden-shed

Cover the roof of the shed with roofing felt, making sure the strips overlap at least 2″. Secure the tar paper to the plywood sheets with roofing staples. In addition, cut a large piece for the ridges. Install the asphalt shingles starting with bottom left toward the top of the shed. Read the manufacturer’s instructions.

STEP 4: Building the 10×12 gable shed doors

Fitting-the-double-door-jambs

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

Assembling-the-double-door-frame

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.

Assembling-the-shed-doors

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-shed-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.

Side-shed-door-frame

Fit the door jambs around the side door opening. Align the edges flush, drill pilot holes and insert 3 1/2″ screws to lock the jambs into place tightly.

Side-door-assembly

Assemble the side door using the same techniques described above. Build the 2×4 frame with 2 1/2″ pocket screws and then attach the panel with glue and 2″ nails.

Fitting-the-side-shed-door

Fit the door to the opening, align the edges and lock it to the jambs with hinges. Install a latch so you can lock the door. Alternatively, you can install a pre-hung door.

Fitting-the-window-trims

Install the 24″x32″ window to the side of the garden shed. Next, attach the 1×4 trims around the window. That will enhance the look of the shed.

10×12-gable-shed-plans

You can add decorative trims to the shed to make it pop. In addition, add a vent to make sure the air circulates properly inside the shed.

How-to-build-a-gable-shed-10×12

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.
