12×24 Shed Plans

This step by step diy project is about 12×24 shed plans. I have designed this large storage shed with a gable roof, so you can organize your tools or to use it even as a workshop. This shed features double front doors, a side door and windows. Before starting the project, make sure you check out the local building codes, so you can comply with the legal requirements. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.

When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day. See all my Premium Plans HERE.

How to build a 12×24 shed

Building the floor frame

The first step of the project is to build the frame of the floor. Cut the components from 2×8 lumber and lay them on a level surface. Drill pilot holes and insert 2 1/2″ screws to lock them together tightly. Make sure the corners are square and measure the diagonals until they are perfectly equal.

Fitting-the-joists

Cut the rest of the intermediary joists at the right dimensions and then fit them to the floor frame. Place the joists every 24″ on center and make sure the corners are square. Use joist hangers to secure the beams to the frame of the floor.

Fitting the skids

Select the location for the shed to suit your needs and making sure it complies with the local building codes. Level the surface with attention and then compact a thick layer of gravel. Fit the 4×4 skids and then attach the floor frame. Align the edges flush and use rafter ties to lock them together tightly.

Fitting the floor sheets

Fit the 3/4″ plywood sheets to the floor frame. Align the edges flush and leave no gaps between them. Insert 1 5/8″ screws every 8″ along the joists, so you can lock them into place tightly.

Section-with-window

Next, you need to build the side walls for the 12×24 shed. Considering the size of the side walls, it would be a lot more manageable to make two sections and then joint them together to the floor of the shed.

Use 2×6 lumber for the double headers. Sandwich a piece of 1/2″ plywood between the two beams and use 2 1/2″ screws to lock them together tightly. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 24″ on center, as shown in the diagram. You can adjust the size of the window opening to suit your needs.

section-with-door

Build the other section of the side wall from 2×4 lumber. As you can easily notice in the plans, you need to adjust the size of the door opening to suit your needs. Fit the double header into place.

You should adjust the size of the opening according to the door you are going to install.

Side wall with window – Frame

Lift the wall frames and set them to the floor frame. Align the edges flush and plumb them with a spirit level. Drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor. Join the two sections together with 2 1/2″ screws and then fit the top plate.

Side-wall-partition

Build the two sections for the other side wall of the shed. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Align the edges flush and make sure the corners are square.

Assembling the side wall

Fit the two sections on the floor of the shed. Align the edges flush 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 tightly with screws. Center the top plate into place and then lock it into place with 2 1/2″ screws.

Back-wall-frame

Build the back wall for the 12×24 gable shed from 2×4 lumber. Cut the studs and the plates at the right dimensions. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 24″ on center and make sure the corners are square.

Front-wall-frame

Framing the front wall is a straight forward job. Therefore, you need to leave enough space for the door opening. You can adjust the size of the opening to suit your needs. Use 2×6 lumber for the double header. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 24″ on center for a professional result.

Assembling the shed frame

Fit the wall frames to the floor of the shed. Align the edges flush and drill pilot holes through the bottom plates. Insert 3 1/2″ screws to secure the frames into place tightly. Moreover, you need to lock the adjacent walls together tightly, by drilling pilot holes and insert 3 1/2″ screws.

Side wall – Siding

Fit the T1-11 siding sheets to the side of the wall. Align the edges flush and leave no gaps between them. Use 6-8d nails to secure the sheets into place tightly.

Side wall with window – Siding

Fit the sheets to the opposite side of the shed. Make the cuts around the window and door openings, so you can fit the T1-11 siding sheets into place. Align the edges flush and insert 6-8d nails, every 8″ along the framing.

Back wall – Siding

Fit the sheets to the back of the shed, as well. Align the edges flush and insert 6-8d nails to lock them into place tightly.

Front wall – Siding

Fit the sheets to the front of the shed, as well. Make the cuts so you can fit the sheets around the opening. Align the edges flush and insert 6-8d nails, every 8″ along the framing.
