This step by step diy project is about 16×20 gambrel shed doors and trims plans. This is PART 3 of the large gambrel storage shed project, where I show you how to build the double doors for the storage shed and how to fit the decorative trims. 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. 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 a few day. See all my Premium Plans HERE.

Building shed doors
First of all, you need to attach the 2×4 jambs around the opening. Align the edges flush, drill pilot holes and insert 3 1/2″ screws to lock them into place tightly, every 8″ along the framing.
Build the door panels from T1-11 siding and the frame from 2×4 lumber. Start by assembling the door frame using 2×4 lumber and pocket holes. Use 1 5/8 screws to lock the panels to the frame. Add glue to the joints and align the edges flush. The door panels are the pieces that you cut out for the door openings.
Fit the double doors to the front opening. Align the edges with attention and use hinges to lock the doors to the jambs. Install a latch to lock the doors into place tightly.
Fit the PVC windows to the sides of the barn shed. Fit the trims around the windows. Fit the 1×4 trims to the sides of the shed. Align the edges with attention and insert 2″ nails, every 8″ along the framing.
Fit 1×4 trims to the back of the shed, using the same techniques described above. Fit the trims to the front of the shed, as well.
Last but not least, you need take care of the finishing touches. Fill the holes with wood putty and then smooth the surface with 120-220 grit sandpaper. Apply a few coats of paint or stain to the components, so you can protect them from decay and so you can enhance the look of the shelter. Check out PART 1 and PART 2 of the shed, so you can learn everything you need to know about building the floor, walls and roof for the shed.

I am confused about the materials list. The first half (with letters in front) looks like a list of cuts, and the second half look like materials list, but they never match up. Either there is not enough materials, or too much. Just look at this part C for example.
Cuts says 8 2×4’s total, but list says 10.
Cuts says 16 1×4’s, but list says 12.
All three plans seem to suffer from numerous mistakes like these, or I am not understanding something.
This is true for all parts, A, B, and C.
Then I thought, maybe the materials are meant to be combined from all three parts, but when I look at it that way, it still does not match up.
Can you email me when you can explain the answer?
You are overthinking it, my friend. You want to be right, but you are not. Can you see the “2xDoor”? That means there are 2 doors, which doubles the materials. The shopping list makes sense. For all the DIY-ers following my blog, please focus more on building projects instead on looking for errors where there are none. Thanks.
