  1. Hi Just wondering what measurement the 12 x 12 is in Eg (feet , Meters …..)

    • Dude, 12×12 is 12ft by 12ft, standard measurement for sheds on the market. Not to mention the plans use an apostrophe (‘) for the dimensions of the building. ‘ represents feet, and ” represents inches.

      If you need measurements in meters, go to google and type ‘ feet to meters ‘ and it brings up a converter in google’s search engine.

      12ft = about 3.6576 meters, so 3.6576 x 3.6576 meter buidling

      • i see, thank you very much for explaining. It can be quite confusing to see when it means inch and when foot when you dont know the apostrof rule.

  2. Very good detail, enjoy just reading them, can wait to be able to start, all projects excellent.

  3. I’m a bit confused after looking over the material list. The number of 2x4x8 listed is (88) which must be an error unless I’m missing something. Could you explain?

    Thank you,
    Mike

    • You need 50 for the walls, 22 for the roof rafters, 5 to be cut up for the king posts, and the remainder for door and window framing.

  4. these are good simple prints! all I would add is z flashing for the window top trim, bitchathane and flashing for the roof, and possible a vapor barrier for the grade.

  5. hello,
    Thanks for the free 12 x 12 shed plans, it is 12 ft tall which is perfect for me since my town regs for a shed is 144sqft 12ft tall.
    I would like to leave the king post out so I can use the rafters for storage.
    do you think that would be ok?

  6. Is it a standard 12″ overhang? I want to add vented soffit to keep insects, particularly bees out.

    • Rick P. ("I Wood if I Could")

      This shed is not that well sealed. You will have many critter friends no matter what you do.

      Before I sided my shed, I cut the ends of the Lower Cords 26.5 degrees (opposite angle to the peak) so that a flat side was parallel to the studs (perpendicular to the ground) — the “Fascia”. I cut 2×4’s to run flush from the lower corner of the Fascia to the corresponding wall stud — the “Soffit”. Then I sided the shed. I cut siding pieces to size and attached them to the under side of the Soffit boards after cutting in soffit vents. Then I attached a 12’+ 1×6 to the Fascia ends so that it hung down over the soffit board about an inch. Fill in the ends with spare trim.

      Remember, if you want air circulation to work, you need to install mushroom vents or a ridge vent in the roof.

  7. Do you know the approximately cost of materials for this 12 x 12 shed?

    • I did a 10X10 shed and materials cost about $1,500. I had the roof trusses made by a truss company; the 10X10 required 6 trusses (put them on 2′ centers) and they cost about $150. I supplied the truss maker the truss drawing from the plans and the pre made trusses worked great; saved a lot of time. Invest in a nail gun and a small compressor if you do not have one; makes the job much easier.

    • I love your plans! I am wondering about using rafters instead of trusses. I would like to have a loft for storage at each end. I’m thinking the trusses would prohibit access to the lofts. Is it necessary to use the trusses? and not rafters? Your thoughts and opinions would be appreciated.

      • Rick P. ("I Wood if I Could")

        I built a 12′ x 16′ shed. I left the King Post out of all the trusses. On the middle five trusses I left out the Lower Cord. On those five I used Hurricane Ties and extra blocking for stability. On the front and back trusses I doubled up the Lower Cord to strengthen the frame for the loft floor. I also doubled the Lower Cord on the two trusses closest to the center opening. For added lighting, I installed two pairs of 12″ x 12″ plastic fixed skylights side by side in the two center roof bays about 12″ down from on each side of the peak. It has been almost 10 years now and everything is still tight and firm.

  8. your plans are very well detailed and are very much appreciated , thanks a lot

  9. Perfect!! I am adding a skylight box to it with the top and bottom removable to be able to access my well housing, dual pressure tanks sit beside that. Then to fit yard tools tractor and ATV in there. Have to make room for the wifes car in garage,

  10. 1st: Is there any disadvantage to making the wall height 6′-6″ as opposed to 7′-6″?

    2nd: Is there any reason (other than code) why I can’t use 24″ O.C. spacing for wall studs and roof rafters?
    I have existing Gambrel roof shed with no king stud and snow load is no problem with that one.

    3rd: Sounds lazy, but is there a material list that eliminates the side door and window stock?

    • Rick P. ("I Wood if I Could")

      Shorter wall height is fine. You just end up with less headroom.

      I used 24″ on center for both the walls and roof (made roof trusses from 2×6’s) and everything has be fine.

  11. simple, straight forward plans, and that’s a compliment not a put down in in manner. built my grandchild a tree house from these plans. thanks a lot

  12. Is it possisble to change tje roof from 6:12 pitch to a 4:12 pitch and if so how can i figure my angle cuts for that roof instead

    • i would like rafter plans for 14×24 shed with salt box roof if possible angle cuts and length of front and back rafters

    • Rick P. ("I Wood if I Could")

      Google makes a simple, easy to learn CAD software called “Google Make” (it used to be called “Sketchup”). There is a free version and one you pay for. The free version is plenty good. I have been using it for 7+ years. It only takes a couple of hours to do the tutorial and you can start designing in 3-D. You can draw a board and use the Protractor key to rotate a line on the end to get your angle.

      Another quick way would be to get a large piece of paper (perhaps a piece of poster board from the Dollar Store. Draw a rectangle that is 12″ wide by 24″ long. On one of the 24″ legs, measure in 4″ from the corner. For Kalief: Draw a line from this point down to the opposite corner. This angle is a 4″ (“Rise”) by 12″ (“Run”) pitch. Use this as a template or use a protractor to calculate the angle.

  13. on the 9th picture you indicate the following: Cut 2×4’s to size and install between the rafters with 3 1/2″ nails.
    Do you toenail the nails into the rafters or are the 2×4’s placed short side up?

    • Rick P. ("I Wood if I Could")

      Stand the boars up on the 1-1/2″ side.

      Toenailing is fine. However, I would put every other board in place and nail each through the rafters into the ends of the the boards. Then I would toenail the others in between. Just me!

  14. I couldn’t find anything that tells me how many shingles I need for this project.
    Did I miss something?

    • Hey Barbara,

      I did not see quantity of shingles for this or the 12×16 shed. With that a bundle of singles covers 33.3 sq ft, I’d round down to 32 sq ft per bundle. The roof looks to have about 224 total sq ft so I’d get 8 bundles. Your going to need extra for the starter row, ridge and waste…

  15. Need engineered drawings to submit to Brevard county in Fla. for a 12 x 12 shed w/ high walls, possibly storage over 6’6″ inside height

    • Rick P. ("I Wood if I Could")

      If they need to be stamped by an architect or engineer, that is going to cost you some money. If all you need are dimensional drawings and you are computer savvy, download the free version of “Google Make” CAD software and run the tutorials. Using the drawings on this site and a little estimating (for door & window detail), you should be able to make line drawings of each wall and of the roof structure.

  16. I am disappointed in the lack of detail. The door construction has no measurements. There is no explanation concerning the installation of the siding. There are no vents for air circulation

  17. Very well explained plans. Bless you, my friend for sharing so much information for free!

  18. Looking. For a 10×12 shed plan withGable roof at fight angle to each other

  19. New user/reader here and no craftsman but have added on/doubled size of our house. Like someone else, just like reviewing plans. Like the barn look on the 8×8 Gambrel and similar to one I would like to erect close to the house for a generator. In Florida, would like to erect a hip roof version if anyone has something like that to share. Read RickP note, for air circulation, have always used a ridge vent. Is a mushroom better? never used one

  20. Any reason why I couldn’t use 2×10’s to get increased loft space for storage?
