Hello everyone! This is my first time posting here, but I've seen some great info on here so I figured I'd ask you guys.

I have a 12x16 shed right now, but it was very poorly built and is falling apart so I've decided to rebuild it. The foundation is still in good shape so I'll just be rebuilding it from the floor up.

I've drawn up some plans for it, and I was wondering if I could get yall's input on them. I've done some research on how it needs to be done and designed plans from there but it would be good to get some other eyes on it. I'm not an engineer or an architect, but I have done some construction in the past.

Looks OK by me, why not make the walls an even 8' high to reduce the trimming of the plywood sheathing?

Wall height was my first thought too.

6'4" door wouldn't work for me, but maybe you are limited on height for permitting?

What is with the weird stud spacing? You want them 16 oc, and eat up whatever is left in a smaller bay at one end. Evenly spaced like you have it doesn't play nicely with sheathing.

I'd use an osb with an integrated wrb (weather resistant barrier) , like zip, LP weather logic, or gp forcefield. Housewrap ***** to work with

You don't need a full 2x for the ridge as it's just a nailer. 1x is plenty, but I would do site-built trusses instead, anyways. You can build them on the ground and stand them solo, if needed. A lot less up and down and it's easier to control for variations, especially for a novice.

Spend plenty of time getting walls plumb and square. If you don't, you'll pay for it when doing the roof and finishes

Agree w/ Mike. I'd build trusses using an extra sheet of osb to cut out joint plates (probably wrong term) to glue and screw your 2x6s together. I would build it like this w/o the extra reinforcement pieces.
The truss sits on the wall so the tail pieces of the rafters hang out beyond the wall to whatever length looks good to you. Instead of your 2x6 under the roof sheathing use a 1x6 as a cap for the tail piece ends. BTW it is kind of a pain but build one truss and then build the 2nd on top of it. Now move it away and build all the rest using the first as your template. These are pretty simple but the one time I helped build trusses we just kept building on top of the previous one. We noticed around truss 5 that we were accumulating some errors that were adding up. So we moved them all and built the rest on top of the first. RE; walls, build them so your osb has a stud to be screwed/nailed to. The 12ft ones are easy using 3 sheets. I see your sides are 15'5" so I assume they will fit in between the end walls. When you build them install your osb so it overhangs the last stud by the 3.5-4" thickness of the end wall. This way you nail the osb onto the 15ft wall and also nail it to the ends of the 12ft wall. Design wise, I'd start at one end of the 15ft wall frame and place your studs so they are at the 16" and 32" and 48" of the osb sheets. The osb is what gives the wall it's strength so it needs good support.

I did a 12 x 16 shed that was an 84 Lumber kit package 30-plus years ago. I hauled the materials to the house with a couple of trips in my old '67 Chevy G20 van, and a buddy and I assembled and roofed it entirely in a single two-day weekend. It has stood the test of time, and was a very cost effective solution. An option to perhaps consider.

Hi, I echo the comments from the previous replies. Go 16" oc stud spacing, so the sheathing edges always land on a stud, make sure to account for the first stud when starting out, and the last stud will be spaced a bit different as mentioned.

Also go 8' high on the walls. If you made it shorter to comply with some sort of maximum height restriction, I would reduce the roof pitch to compensate. Your door opening may be too short as it is, especially if you decide on a roll up door which at fully up is still 4-6" below the opening.

I built a 12x16' shed a few years back, and documented it in this thread.

Wall height was my first thought too.

hadn't thought about that, thanks. height restriction is not an issue, i just wanted it a little taller than what i have now, but the full 8' make the most sense with less wasted materials.

Your door opening may be too short as it is, especially if you decide on a roll up door which at fully up is still 4-6" below the opening.
the opening is 6'6" tall, but it would make more sense for a 7' tall opening if i raise the sides to 8'. I was planning on doing double doors like what i have now, since they're pretty easy to make. i don't really need a roll up door since this will mostly be for storage.

I thougth it would look nicer from the inside, but that make a lot of sense. thanks for catching that. that would be a pain to work with them not lining up

never heard of that, but i'll look into it. I figured housewrap would do a decent job, but that style OSB would be much easier to work with

When you build them install your osb so it overhangs the last stud by the 3.5-4" thickness of the end wall. This way you nail the osb onto the 15ft wall and also nail it to the ends of the 12ft wall.

good idea, i'll see about doing that.

Agree w/ Mike. I'd build trusses using an extra sheet of osb to cut out joint plates (probably wrong term) to glue and screw your 2x6s together. I would build it like this w/o the extra reinforcement pieces.
i went with the ridge beam style because it seems like it is a little stronger, the one i have now had the joint plate style and its starting to bow in the middle (part of the reason i'm rebuilding it)

Spend plenty of time getting walls plumb and square. If you don't, you'll pay for it when doing the roof and finishes
the first go kart i built i didn't square anything when i was welding it, and it was a pain trying to do any modifications to it later because nothing is square or even so you have to just hope its square. learned my lesson there.

I built a 12x16' shed a few years back, and documented it in this thread.
looks good! i ran across that thread when i was looking for ideas for this one. i like how you left out some ceiling joists, makes it easier to get big stuff up there. i wish i could get a concrete pad for this one, but the one i've got is still in decent shape.

ok, got a few things to change, but thanks everyone for your help!

If your current base/foundation is only in 'decent shape' you may want to reconsider not replacing it.
the plywood floor is kinda beat up, so i'm gonna replace it with new. from the outside it still looks good, but when i pull up the old floor i'll check on the condition of the base. though, it is at least 20 years old, probably more, so i might end up just replacing it anyway

edit: now that i read this it would make the most sense just to plan on replacing it, due to its age. it was probably not made from PT wood to begin with, and if it was it's probably worn off.
