Don’t believe us yet? Here’s a sample 8×20 Gable Shed plan that you can follow and see the magic happen yourself!
Step # 1: Check the Rules Where You Live
Rules for sheds vary by town. Check your local permit office before you build.
Step # 2: What Type & Size of Shed Should You Have?
Know the type and size of your shed before you head on to the market to get your supplies. Depending on the type of roof, sheds come in 3 types.
-
Lean to Shed: A lean-to shed is built against a wall and has a roof sliding downwards from the hind wall to the front. This is usually smaller in size and best for storage purpose.
-
Gable Shed: Gable shed is the most commonly used shed around the world. It is easy to construct and can be used for multiple purposes.
-
Hip Roof Shed: A hip roof shed is exquisitely designed and adds a lot of value to the property. It is suited for larger sizes and is a little complicated to construct.
An 8×20 Gable shed serves both as a great storage spot and provides enough space to carry out your activities.
Step # 3: What will be the Height, Width and Other Dimensions?
An 8×20 shed is quite spacious. It has a maximum roof height of 12 feet and 4 ¾ inches and a roof spanning at the width of 21 feet. The front wall has a width of 8 feet and 1 inch. The width of the side walls varies to accommodate the roof slope. All walls have a height of 7 feet and 8 inches. The side wall also accommodates a big garage door and a 3×3 window is adjusted on the front wall.
Step # 4: What Materials and Tools are Needed?
The right materials and tools are necessary to build a sturdy structure. A typical gable shed is built using pressure treated timber, timber for rafters, joists, studs and gussets etc, shingles, fascia boards, soffits, T1-11 siding panels, tongue and groove plywood etc. the necessary tools include hammer, saw, wrench, galvanized nails etc. You will have to buy the door and window for the shed separately which are not included in this plan.
Step # 5: How to Make the Foundation and Floor?
The first step of construction is making the foundation. Lay the skid foundation using pressure treated timber. Hammer the joists and bands on the skid foundation to make the framework along an 8×20 dimension. Once the foundation is fixed, cover it with tongue and groove plywood to make the floor. Make sure you use galvanized nails to fix the foundation and make the flooring.
A Few Pointers:
-
Make sure to remove any clutter or plantation from the area where you are placing the foundation.
-
Make sure you building the foundation exactly where you intend to place it. Relocating the structure might compromise its integrity.
Step # 6: How to Make the Walls?
The structure of the walls is made separately from the foundation and is later attached to the foundation.
-
Start by placing the top and bottom plates 7 feet and 8 inches apart and then attaching wall studs to it using galvanized nails.
-
Cut out space for a wide garage door on the side wall and a window on the front wall. Use cripple studs, L-joints, wall studs, headers and plates to make the wall structures.
-
Once the structure is intact, cover it with T1-11 siding from the outside. Finally hammer the walls on the foundation.
Tip: you could use temporary brackets to erect the wall structure on the foundation.
Step # 7: How to Make the Gable Roof?
Making a gable roof can look tricky but following these simple steps it can be done easily.
-
Start by making trusses on the ground. Make trusses using rafters, gussets and cross pieces. All your trusses must be identical otherwise your roof framework will not be even.
-
Install the trusses over the wall studs keeping them flush with the outer edges of the wall plates. Use galvanized nails to hammer the trusses to the studs.
Step # 8: How to Cover the Roof Framework?
-
Once you have made the framework, cover it with ¾ inch thick plywood as the first layer.
-
After the first layer, you should install the asphalt shingles to the roof to make it leakage proof.
-
Refer to the manual that comes with the asphalt shingles to learn how to install them.
-
You can also use cedar shingles if your state approves or any other different roofing but plywood and asphalt shingles are recommended and are friendly on the pocket.
Step # 9: Installing Fascia Boards & Soffits
Since you made your roof leakage proof with shingles, install fascia boards on your walls to make them leakage proof whilst giving them a refined look. Also install soffits and trims to finesse your shed’s look.
Step # 10: Adding Some Finishing Touches
-
Refer to the manufacturer’s manual for installation to affix the door and window to your shed.
-
You can additionally insulate your shed to avoid short circuits.
-
Coating the exterior with lacquer will protect the wood and give your shed a refined look.

What fits in an 8x20 shed
An 8x20 is a long, shallow shed that fits along a fence or a property line where a square shed will not.
- Door on the long side. The 108 inch (9 ft) door opening sits on a 20 ft side wall, so you reach most of the floor from the door instead of walking to the back.
- Long items. Kayaks, ladders, lumber and pipe can lie along the back wall.
- Two zones. Park a mower or cart at one end and set up shelving or a potting bench at the other.
- Check depth first. The floor is 96 inches deep, so measure anything you plan to park against that number.
What the 8x20 plan and material list include
- A material list with the quantity of each item, plus the hardware and tools, printable for the lumberyard. It is written for this exact 8x20 size.
- 40+ step-by-step instructions: skid foundation and floor, wall framing, gable trusses built from rafters, gussets and cross pieces, roof sheathing and asphalt shingles, then fascia, soffits and trim.
- 3D rendered images of every side and the roof, with a pro tip for each section.
- Delivery by email right after checkout, in a PDF that is easy to read on a phone.
The window is on the list as a prefabricated unit. The roll-up door is bought pre-built.
Before you build an 8x20 shed
- Site. A 20 ft shed needs a long, flat, well-drained pad. Clear plants and loose soil, and level a compacted gravel base (This Old House: gravel shed foundation). See our shed foundation guide too.
- Skid length. Long treated skid boards can be hard to find at 20 ft, so check what your lumberyard stocks before you order.
- Trusses. Build the first truss on the floor deck, check it, then use it as the pattern so every truss matches.
- Permits. At about 12' 5" tall and 160 sq ft, this shed may need a permit or meet height and setback limits in your town. Rules vary, so check your local permit office.
- Lumber care. Keep lumber stacked off the ground and covered, since wood that stays wet decays faster (USDA Forest Products Laboratory Wood Handbook).
- Safety. Have a helper for raising walls and trusses, and stay off open framing until the roof is sheathed.

Frequently asked questions
Will a riding mower fit in an 8x20 shed?
It depends on the mower. The door is a 108 inch wide roll-up door on the 20 ft side wall, and the floor is 96 inches deep. Measure your mower's length against that depth, leave room to walk around it, and check the width against the door.
What foundation does the 8x20 gable shed use?
A skid foundation. Pressure-treated skids carry the joists and bands, and 3/4 inch tongue and groove plywood makes the floor. Build it where the shed will stand, on cleared, level ground.
Are the door and window included in the 8x20 plan?
The plan frames the openings for one roll-up door and one window. The window is on the material list as a prefabricated unit; the roll-up door is bought pre-built. Install both by the maker's instructions.
