4×12 Shed Plans

This step by step diy project is about 4×12 gable shed plans. This shed is the ideal choice if you need extra storage, but you are fighting with a narrow backyard. This shed would make for an amazing bike shed. Take a look over the rest of my woodworking plans, if you want to get more building inspiration. Remember that you need to select the site for the shed with attention and that you have to comply with a few legal regulations.

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 4×12 shed

Building-the-floor-shed-frame

The first step of the project is to build the floor frame for the shed. Cut the components from 2×6 lumber. Align the edges flush and drill pilot holes through the rim joists. Insert 3 1/2″ screws to lock the joists together tightly, after making sure the corners are square.

Fitting the skids

Fit the 4×4 skids under the frame. Make sure you choose the right location for the shed and even out the surface. Compact a layer of gravel under the skids. Lock the floor frame to the skids using rafter ties.

Floor

Fit the 3/4″ plywood sheets over the floor frame. Align the edges with attention and then drill pilot holes through the sheets and insert 1 5/8″ screws, every 8″ into the floor frame.

Front-wall-frame

Use 2×4 lumber for the wall frames. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Make sure the corners are square and align the edges with attention. Build the double headers from 2×4 lumber and then fit 1/2″ plywood between them. Toenail the double header to the sides and to the top.

Back-wall-frame

Build the back wall from 2×4 lumber, as well. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs, as well. Make sure the corners are square and align the edges flush, for a professional result.

Side-wall-frames—4×12-shed

Build the side walls from 2×4 lumber, as well. 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. Make sure the corners are square and align the edges flush.

Assembling the shed frame

Fit the wall frames to the floor and align the edges flush. Drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor. Moreover, you need to lock the adjacent walls together tightly using 3 1/2″ screws. Use a spirit level to plumb the walls vertically.

Side wall – siding

Fit T1-11 siding sheets to the sides of the shed, as well. Align the edges flush and insert 6-8d nails, every 8″ along the framing. Leave no gaps between the sheets for a professional result.

Front wall – Siding

Fit the siding panel to the front of the shed, making sure you align the edges with attention. Cut out the opening with a saw. Smooth the edges flush for a professional result.

Back wall – Siding

Attach the T1-11 siding sheet to the back of the shed, as well. Use 6-8d nails to lock the sheet into place tightly.

Don’t forget to take a look over PART 2 to learn how to build the roof for the shed, as well as how to frame the front door. This small shed is ideal for narrow backyards. For example, I think this would make for a great bike shed.
