I really like the shed plans. Can probably build this in my backyard, yet, no money for timber yet. Does one happen to know anything about building apprentice I beam saw horses. They can hold a lot of weight. And can be modified to have a tool tray in the bottom. Just an idea. Thats all.
Just finished building a shed! This would have helped me but saw this after. I learned from u!
thanks
for the plans i will be able to construct this with all the layout plans and materials
Thanks! How can I build same 12×12 shed? Thank you for your help 🙂
Thanks for the great plan. I modified it to suit my requirements. I added height to the walls so that the back wall was 8 feet high inside. I opted for a single wide door centered in the front and a vent window above the door. I also used 16′ center stud and roof joist spacing and ribbed steel roof panels.

I would like to do the same.
What was the height of the front wall?
Still pitch 12/2?
Why 16″ oc? Was it to do with the steel roof panels?
Thx,
Nees help building a shed 12×12 please
Would be great if you including in the shopping list details to use cladding like T&G boards.
looks like an easy build i would like to try this
We are planning to build a bunkie 10 x 20 and these plans have answered a lot of our questions. We will be wanting to insulate so need to figure that out for the ceiling. Thanks for getting us started.
Hi Valerie:
Did you building the 10 x 20 lean roof shed? If so how much were the materials?
Thanks for the help.
Matt
Our habitat builds storage sheds for our families. I am eager to build this one. Many thanks!
I built this shed and the plans are very helpful. I decided to add 12” to the height because it felt a little claustrophobic. If you’re going to be using it as a hangout I would recommend going taller. Altogether a solid plan. Would recommend.
Love this plan! Exactly what I had in mind. Can’t wait to get started!!
want to make this with a 8′ back wall. do i have to bring the front higher for the pitch of the roof?
and realy would like to make this 12’x12′ do you have plans for that ?
Est. Cost?
I just input everything for a 10′ x 12′ lean to shed into my local Lowes shopping cart and it came to around $1,250.
Hi Michael:
Did you build it? We are thinking about giving it a go.
Please let me know.
Thanks – Matt
Currently building this, after making sure it is weather tight, and climate controlled, coming to about $1800-$1900.
Did you go 16 or 24 on the walls? Do you klan on insulating it?
I was looking to build this shed in Minnesota. Does anyone know if the 2×4 roof rafters are adequate for this climate?
Is it possible to add insulation to that kind of roof? I live in the mountains in Canada and I’m looking for a project I can improve over time.
Hi Fred. I’m in Ottawa and will be building something similar of my own design, but 10’x14′
Regarding insulation: it would not be difficult to install insulation batts up between the roof rafters after the fact. Roxul comes in 23″ wide batts, or you could use insulation foam board which come sized at 24″ so you’d have to shave off 1-1/2″ to fit and get the screws with large plastic washers to affix the foam board to the purlins.
Just a note about the roof and snow loading. If you’re in the mountains (BC? Alberta?) you might want to up your roof rafters to 2x6s. That’s a shallow pitch roof, and yes metal panels will shed the snow better than shingles but you will probably still get some accumulation especially if you get any freezing rain first (the screws in the roof panels plus ice will make enough grip to hold the snowpack. Alternately, if you build the roof with 2×4 rafters or you find you’re still having sagging issues you could “truss” the rafters after the fact by adding horizontal rafters and triangle bracing.
Hope that helps,
Very interesting, but as a word of caution – anyone here in Britain needs to be aware that there is a height restriction for garden buildings of 2.5 metres (just under 8 foot 2 and a half inches). A simple way around this without losing too much internal height might be to build this shed in a double lean-to configuration, where the side walls are only one foot below the central ridge.
I built this and the plans are great. I changed it a little so the door was in the center – I plan to add vents and add a couple of small windows later on.
One question I have is… Has anyone had any issues with water? I was thinking of putting something along the high end of the roof but not sure that is necessary?
I was going to post a picture but can’t seem to?
I am wanting to build this shed for my husband, can you give me a guess-tamation of the price? Thank you!
Interested in the plans please.
We enjoyed building this shed and are very pleased with it. (I still have to finish the eves). The plans were great! We added a second window, insulated the walls with fiberglass and the roof with ridged foam boards spray foamed in and then fiberglass below that. The interior walls and ceiling were then covered with 1/4″ plywood that we ripped into a little over 7″ wide strips. I made a few mistakes along the way but all in all it came out nice. And the wife loves it! We put a15amp and a 20 amp circuit in it so we could have an extra refrigerator, toaster oven and ice machine inside. Thank you for a great set of plans!
