12×12 Shed Door – DIY Plans

This step by step diy project is about 12×12 shed door and trims plans. This is PART 3 of the garden shed square project, where I show you everything you want to know about framing the door and fitting the trims. Take a look over the rest of my woodworking plans, if you want to get more building inspiration. Remember that you need to select the site for the shed with attention and that you have to comply with a few legal regulations.

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 door for a 12×16 hip roof shed

Fitting the jambs – 12×12 storage shed

First of all, you need to build the door jambs. Cut the jambs from 2×4 lumber and attach them around the opening. Make sure the edges are flush, drill pilot holes and insert 2 1/2″ screws.



Build the door panels from T1-11 siding and the trims from 2×4 lumber. Assemble the door frame with pocket screws. Align the trims flush with the door panels and secure them together with glue and 1 5/8″ screws. Use the pieces that you have cut out when installing the siding sheets, for the door panels.
