14×20 Lean to Shed Plans

Ovidiu 0 FavoriteLoadingAdd to favorites List YOUR FAVORITES GapDice RANDOM PLAN

This step by step diy project is about 14×20 lean to shed shed plans. This large lean to shed is ideal for storing large items, such as lawn mowers, tools, bikes and other items. This shed features a large 8′ roll up door to the front and a side man door to the side. Make sure you comply with the local codes before staring the project. 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.

14×20 Shed Plans

Floor frame

Floor frame

First of all, you need to build the floor frame for the 14×20 lean to shed. Cut the joists from 2×6 lumber at the dimensions shown in the diagram. Lay the joists on a level surface and then align the edges flush. Make sure the corners are square and then drill pilot holes through the rim joists. Insert 3 1/2″ screws to lock the components together tightly.

Fitting the skids
