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 plans, section, and elevation drawings showing each part of the frame. You can easily budget for and purchase materials with the included timber and fastener lists. The second 33-page drawings show each cut on every timber in the frame, so no guesswork is involved! It is formatted to print on 11×17 paper. Both sets are ready for instant download once you make your purchase.

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.
That could certainly be done- if you would like us to customize the plan for you check out this page
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.
We don’t currently have any images of this frame, the design was just created a couple of months ago. Stay tuned.
What is the angle of this roof?
Hi Richard,
The roof slope is 4 over 12.
Moyer
Hello,
I’m currently building this and am more then happy to share how it turns out!
Cheers!
Luke
We’d love to see pictures!
Luke, I’d love to see how you finish this out! This was my creation with the incredible help of Moyer and Brice (took a great design, added the bump out and got rid of the center post so really the hard work was done!). We’re at 9200 ft elevation in Colorado and off grid so everything is taking 5 times longer than it should…we’re SO hoping to raise the timbers the fall of 2021 but I’ll be lucky to have the foundation set by then. Would like to know how you’ll wrap it and your roof system.
How would we build this without the braces so SIP’s and clerestory windows can be added?
We would not recommend eliminating the braces without consulting an engineer. Braces are critical to the strength of any frame. Our custom design department might be able to help you- you cam find out more information on those services here.
What are the dimensions between posts? Is it 8′ 8′ 4′ from the side and 10 between the backs, 20′ in center, and not sure about the front. Also what is the height at roof, back, front and bump out,
thank you much.
The distance at the rear of the frame is 10′-0″ from outside to venter of the posts. The heights are 9’0″, 12′-2″, 15′-5″ and 16′-9″ tpo the top of the plates.
