12×20 Shed Doors Plans

This step by step diy project is about 12×20 shed doors and trims plans. This is PART 3 of the large lean to 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. 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.

How to build double shed doors

Fitting the jambs

Attach 2×4 boards around the door opening. Align the edges flush, drill pilot holes and insert 2 1/2″ screws, every 8″ along the framing.

Building-the-doors

Build the door panels from T1-11 siding and the trims from 2×4 lumber. Use 2″ screws to lock the panels to the trims. Add glue to the joints and align the edges flush.

Fitting the double doors

Fit the door to the opening and align the edges flush. Attach hinges to lock the door to the jambs. Install a latch to lock the door tightly.

Back wall trims

Fit 1×4 trims to the back of the shed. Align the edges with attention and insert 2″ nails, every 8″, to lock them into place tightly.

Side trims

Fit 1×4 decorative trims to the sides of the shed. Align the edges and insert 2″ nails, every 8″ along the framing.

Front wall trims

Fit the 1×4 trims to the front of the shed, as well.

12×20 Lean to shed Plans

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.
