12×18 Gable Shed Doors Plans

Ovidiu 2 GapDice RANDOM PLAN

This step by step diy project is about 12×18 shed roof plans. This is PART 3 of the sturdy 12×18 storage shed, where I show you how to build the double front doors and the side door. Make sure you check out the first and second part of the project, so you learn how to build the frame of the shed, as well as the roof. You can easily adjust the size and the design of the doors, to suit your needs. 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.
