12×8 Double Doors and Trims Plans

by Ovidiu


This step by step diy project is about 12×8 shed doors plans. This is PART 3 of the gable shed project, where I show you everything you want to know about framing the double doors 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 double doors for a 12×8 shed



The first step of the project is to attach the 2×4 jambs around the door opening. Align the edges with attention, drill pilot holes and insert 2 1/2″ screws to lock them into place.



Build the door panels from T1-11 siding and the trims from 2×4 umber. Align the trims flush with the door panels and secure them together with glue and 2″ nails.
