12×20 Gambrel Shed Doors Plans

This step by step diy project is about 12×20 gambrel shed door plans. This is PART 3 of the gambrel shed project, where I show you everything you want to know about fitting the trims and building the doors. 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 shed doors

Double-door-jambs

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.

Building-the-double-shed-doors

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.

Fitting the double shed doors

Fit the double doors to the front opening. Align the edges with attention and use hinges to secure the doors to the jambs. Moreover you need to attach one latch to the doors, so you lock them into place tightly. Fit handles to the double doors.

side door jamb

Fit the 2×4 jambs around the side door opening, as well. Align the edges flush and insert the 2 1/2″ screws, every 8″ along the framing.

Building the side door

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.

Fitting the side door

Fit the door to the opening and align the edges flush. Use hinges to secure the door into place tightly. Fit a latch so you can lock the door into place tightly. Fir handles to the door, as well.

Side wall – Trims

Fit the 1×4 trims to the plain side wall. Align the edges flush and insert 2″ nails to lock them into place tightly.

Back wall – Trims

Fit the 1×4 trims to the back of the wall, as well. Align the edges with attention and insert 2″ nails.
