12×12 Barn Shed Door Plans

by Ovidiu


This step by step diy project is about 12×12 shed  door and trims plans. This is PART 3 of the 12×12 barn shed project, where I show you how to build the doors and attach the trim.  Generally speaking, the trims will enhance the look of the shed and add character to the project. Moreover, I have designed shed with many sizes so check them out, as well. 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, as it will pay off on the long run. 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 about a day. See all my Premium Plans HERE.

Building a barn shed door



Build the trims for the 1×6 lumber. Cut both ends of the trims as shown in the plans. remember that you can easily add overhangs to the front and back of the shed, for appearance. Align the edges flush and insert 8d nails to lock the trims into place tightly.



Cover the roof of the shed with roofing felt, making sure the strips overlap at least 2″. Secure the tar paper to the plywood sheets with roofing staples. In addition, cut a large piece for the top ridge. Fit the side drip edges over the roofing felt, while the bottom drip edges should be fit under. Read the instructions labeled on the asphalt shingle packs before installing them into place tightly. Start with the bottom left side of the roof and install them all the way to the top.



Attach 1×4 trims around the opening. Use 2 1/2″ screws to lock the trims into place tightly.



Build the door for the barn shed from the siding panel that you have cut out in the previous step. Use 1×4 lumber for the door siding. Use brad nails and glue to secure the trims to the door panel in a professional manner.



Fit the door to the opening and lock it into place with hinges. In addition, install a door latch so you can close the door securely.



Fit 1×4 trims to the corners to the front and back faces of the barn shed. Lock the trims into place with 4d nails.



The barn shed sheen from the back has a nice appearance, so it will add a rustic charm to your property.



Seen from the sides, the barn shed proves to be an ideal choice if you want to add storage space to your property.



Make sure you check out the rest of the project, so you learn how to frame the roof and the frame of shed. In addition, I have lots of other shed projects on the site so I recommend you to browse through all alternatives before starting the building project.
