  1. Shed floor measures 10×12. Shed measures 10′ 2 3/4″ x 12′ 2 3/4″ with siding and trim.

  2. What happened to the 10×12 gambrel roof shed that used 2×6 lumber for the rafters, and had optional front overhang

    • I have the same question, what happened to the prior shed plans that used 2×6 lumber for the rafters, and had optional front overhang? I am in the middle of building it and needed some reference material.

  3. Inice look for 12 by 16 plans

  4. not sur of 2×4 block trim, and trim/roof intersection, shingls bow out on trim piece or stop at trim, not understanding that part

  5. Just built this shed, thanks for the great plans. We used post-to-beam brackets to attach the gambrels, and added joist hangars around them to run 2×6 joists across 2/3s of the length to create loft storage. The only real point of confusion is the interface between the roof and the sides, which we dealt with by just having the roof overhang by a couple of inches. Thanks!

  6. What should the measurement be at the bottom of the rafters point to point? I assumed it would be 10 feet, but mine came up 3 inches short?

  7. All these plans look great anyway i could request plans for a 12 x 16 with loft?

  8. These plans are perfect, just what I was looking for. THANK YOU SO MUCH!

  9. Is there enough plywood in this material list to make the gussets and spacers?

  10. WARNING: Do not use these plans if this is your first time building a shed. SO MUCH is left out. We used these plans and are up to the point of putting the roof on. Notice that the walls are 12′ long exactly but the graphic shows being able to use a 2×4 on either end for trim and have the plywood cover the 2×4 trim. This is impossible considering you only have 12 foot of plywood to use. (one 4×8 sheet and half of a 4×8 sheet). There is so much left out of this. How does the roofing sheeting go on? How does the drip edge go on? How does the trim go on? I thought that we could just “figure it out” as we went along but it has caused so much headaches not having a complete plan. It’s hard enough to get a project like this finished in your spare time let alone a project with incomplete plans. The roof is the most important part too, it’s what keeps your stuff DRY which is the whole point of a SHED (to SHED water).

  11. So, after having looked at the plans you should have a 6″ over lap on both roof ends as well as all of the roof trusses in over the side walls in order to put on trim and a drip edge on both side walls. You will need to lengthen the top of the roof trusses accordingly while keeping the 22.5 degree angle. Just cut your upper floor supports to length from 2x6x12’s instead of 2X6x10’s. However you will need to measure and cut supports for the area with no upper floor. That can be achieved by attaching notched 2×4 / 2×6 lumber to come down from the center area of the upper truss area to the over lap the lower ends of the trusses overhang. Don’t forget to trim and use the angles properly to fit this whole overhang properly. This area must be closed giving you a soffit to attach guters and trim to. Also, build small ladder frames to attach the building end supports over the top of the wall siding and it will finish the look for the shed, and don’t forget to finish that soffit area as well. Also, I would put a would put a drip rail, 3 to 6 inches wide and 6 inches past the side of the doors to keep that door frame as dry as possible.
