8×12 Cheap Shed Plans

by Ovidiu


This step by step diy project is about 8×12 cheap shed plans. This compact shed is a relatively roomy storage shed and it is optimized for you to build it fast and on a budget. This shed is not conventionally handsome, but it is sturdy and most importantly cheap to make. Read the local building codes so you make sure my shed complies with your specific 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 8×12 cheap shed



The first step of the project is to build the floor frame for the 8×12 utility shed. Considering this is The Cheap Shed Project, I will be using 2x6s for the joists. Align the edges with attention, drill pilot holes and insert 3 1/2″ screws. Make sure the corners are square and place the joists every 16″ on center.

Fitting the skids

Fitting the skids

Select the location for the shed, so it suit your needs and complies with the local building codes. Lay the 4×4 beams on the surface and then secure the frame to the skids with 3 1/2″ screws or using rafter ties. You could also use cider blocks to lift the floor frame from the ground and protect it from moisture.

Fitting the floor sheets - 8x12 shed

Fitting the floor sheets – 8×12 shed

Fit 3/4″ plywood sheets to the floor frame and align the edges flush. Leave no gaps between the plywood sheets and insert 1 5/8″ screws, every 8″ along the joists. Invest in pressure treated plywood, as it is more durable. However, if you are on a tight budget, you could go for OSB sheeting.



Build the side walls from 2×4 lumber, using the info from my plans. Place everything on the floor of the shed and use 3 1/2″ screws or 16d nails through the plates into the studs. Place the studs every 16″ on center and make sure the corners are square. If you want to save a few bucks, you could go with the studs every 24″ on center, but I show you how I would frame it for myself.



Build the back wall from 2×4 lumber. Drill pilot holes through the plates and insert 3 1/2″ screws or 16d nails into the studs. Place the studs every 16″ on center.



Framing the front wall is a little bit more complex, as you will need to leave a door opening. You can adjust the size of the opening, but I am conservative and I go for a 4′ wide double doors. Notice the 2×4 double header (with 1/2″ plywood in between) and the cripple studs.

Lift the wall frames and then attach them to the floor of the utility shed. 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, by drilling pilot holes and insert 3 1/2″ screws to lock them together tightly.

Rafter - 8x10 Shed Plans

Continue the 8×12 utility shed project by starting to build the roof. Use 2x4s for the rafters and make angle cuts at both ends, as shown in my free plans.

Truss gusset - 8x10 Shed

Truss gusset – 8×12 Shed

Lay the rafters on the floor of the shed, against a straight edges. Use 1/2″ plywood for the gussets or you could simply buy metal plates. Leave no gaps between the rafters and align the edges with attention. Attach the gussets and secure them into place with 1 5/8″ screws.



Fit the trusses to the top of the shed and place them every 16″ on center. Plumb the trusses with a spirit level and lock them to the shed frame with ties. Place the trusses every 16″ on center.

Gable end supports

Use 2×4 lumber for the gable end supports. Toenail the supports to the frame of the 8×10 shed. This back support will make fitting the siding sheets a lot easier.
