20×20 Lean-To Plan


SKU: 36213 Categories: , , , , Tags: ,

If you are looking to build an impressive structure that captures the sun, look no further than this 20×20 lean-to plan! The single-plane shed roof soars up to 16’-9”, creating a high-volume space. That big roof surface would make a great place to mount solar panels with proper orientation. Thanks to the central parallel chord truss, the 400 square feet is a clear span with no central post, so you can utilize the entire space as you wish! The four-foot deep bump-out adds more square footage and dynamic shape to this stunning 20×20 shed roof plan!

  • 4 in 12 roof pitch
  • 400 square feet with 40 square foot bump-out
  • Room to add loft in future
  • Perfect for farm storage, artist’s studio or small cabin

There are two drawing sets to give you all the information you need to build this 20×20 shed roof plan. Both sets are ready for instant download once you make your purchase. The first five-page set is formatted to be printed on 24×36 paper. These five pages include a 3D exploded isometric showing how the parts of the frame relate to each other. Then there are detailed and dimensioned plan, section and elevation drawings of all parts of the frame. We also include full timber and fastener lists, so you can budget for and purchase your materials easily. The second 33-page set of drawings is formatted to print on 11×17 paper.
