20×20 Timber Frame Lean-To Shed Plan

20x20 Foot Timber Frame Lean To Shed

This clear span 20×20 foot timber frame lean-to shed structure provides many opportunities to use as an enjoyable dwelling or open-air structure. Locating it on a sloping grade with a porch is just one of the endless scenarios of how this frame can be positioned. This frame would make a great artist’s studio, workshop, or guest cabin. Let your imagination run.

There are 400 square feet of uninterrupted space, thanks to the parallel chord truss. In addition, the 40 square foot full height bump out adds dynamic shape to the facade and extra room to the interior.  The single-plane shed roof soars to over sixteen feet high, creating a big volume and the possibility of a loft down the road. If you orient the roof to capitalize on the sun, it would be a perfect place to mount solar panels.

The drawings to build this 20×20 foot timber frame lean-to are made up of two sets. The first is a five-page set formatted to be printed on 24×36 paper, which includes a 3D exploded isometric drawing. There are also fully dimensioned plan, section, and elevation drawings showing each part of the frame. You can budget for and purchase your materials easily with the included timber and fastener lists.  The second 33-page set of drawings shows each cut on every timber in the frame, so there is no guesswork involved! It is formatted to print on 11×17 paper. Both sets are ready for instant download once you make your purchase.

  1. I’m really intrigued by this design. Can the sides be bumped out 2′ on either side to make a symmetrical 20′ x 24′ footprint? This could allow for some interesting options like a spiral staircase and 2 bedrooms in the loft.

    I would love to see some of your customers’ finished products for ideas. I purchased 25 wooded acres in the mountains of NC and am planning to build an event center and 10-12 small rustic off-grid cabins. Loft bedrooms and lots of deck space.
