10×12 Run In Horse Shelter Plans

Ovidiu 5 GapDice RANDOM PLAN

This step by step diy project is about free 10×12 run in shed plans. I have designed this small run in horse shelter so you can build it in a few days with basic tools and materials. This shed has a run in front wall and three plain walls. You can adjust the slope of the roof to suit your needs. Take a look over the rest of my woodworking plans, if you want to get more building inspiration. Roof pitch is 3:12.

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. If you have all the materials and tools required for the project, you could get the job done in about a day.

Building a 10×12 run in shed

Base components

Base components

The first step of the project is to build the beams for the base of the shed using 4×4 lumber. Cut both ends of the beams, as shown in the diagram. Make parallel cuts to the indicated areas and then remove the excess with a chisel. Smooth the surface with sandpaper.

Assembling the base of the shed

Assembling the base of the shed

Select the location for the shed and then remove the vegetation layer. Level the surface with a spirit level and then fit the 4×4 pressure treated beams into place. Assemble the base for the shed using 3 1/2″ screws. Make sure the corners are square, drill pilot holes and then insert the screws to lock the base beams together tightly.

Use 2×3 anchors to lock the base into the ground, every 16″. Alternatively, use hurricane anchors if you live an area with strong winds.


Building the shed walls



The next step of the project is to build the back wall from 2×4 lumber. Cut all the components at the right dimensions, after taking accurate measurements. Make sure the edges are flush and check if the corners are square. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place double studs at both ends of the wall, with 1/2″ plywood between them. Fit the studs every 16″ on center.



Build the side walls for the run in shed. Cut the components at the right dimensions and then assemble the frames using the same techniques described above.

Building the posts

Building the posts

Use 4×4 lumber for the front posts. Mark the cut lines on the top of the posts and then get the job done with a circular saw. Make 1 1/2″ deep parallel cuts inside the marked area and then get the job done with a chisel. Smooth the recess with sandpaper, for a professional result.



Attach the walls to the base with 3 1/2″ screws. Drill pilot holes through the bottom plates and insert 3 1/2″ screws into the base beams. Use a spirit level to plumb the posts vertically and then check if the corners are square. Align everything with attention for a professional result.

Fit the posts to the front of the shed. Align the edges with attention and then drill pilot holes. Insert 5″ screws to lock them to the side wall properly. Use a spirit level to plumb the posts properly. Fit the 2×8 support beam to the top of the posts. Make sure the corners are square and align the edges with attention. Drill pilot through the beam and posts and then insert 4″ carriage bolts. Use at least 3 bolts for each side.

    I was wondering if you could possibly make this lean to with materials that are more farm animal friendly the t1-11 siding is not worth spending over $400 to get beat up out in the pasture, if you know what I mean. I was also wondering if you could go into more detail on each step it does get a bit confusing, I love the lean to it is perfect for my horse I just can’t use the materials. Thanks!

      Hi there, what steps do you need more assistance with? Regarding the materials, you can replace the T1-11 siding with OSB, Plywood or 1×6 slats. Choose what suits your budget.

    Nice plans, I’m 75% done with my project. I changed the roof to metal and plan to line the interior with old 2×4’s to add strength and give the run in a custom look.

      That sounds great. Good luck with the project and let me know how it comes out. I would love to feature your project on the blog. You can send a few pics here: http://myoutdoorplans.com/contact/

    Would you be able to tell me how much tin would be needed if I substituted tin for the T1-11? I would be using tin for siding and roof.
