Still trying to figure out how to lay everything out on our new land!  It is a blank canvas! and overwhelming! lol  Im not sure how I want to lay everything out.  Ive got a pretty big square.  Im thinking instead of big barn doing paddocks with lean to.  And maybe get shipping containers for hay and feed.  If I go this route not sure how to lay out paddocks and have a nice flow for feeding and such.  I have 2 horses so will start out with 2 paddocks.  I wish you could move stuff around like rearranging a living room lol!  So does anyone have any input or pictures? thanks I have seen on pinterest 2 shipping containers and they made a roof and an allwyway in between the containers which look pretty neat.  Thinking I could put a wash rack and tie up in the alleyway.  The shipping containers I know mice cant get in so why Im really considering this. 

Make drainage one of your priorities.    

When the weather is bad....rain, cold, snow, wind, etc., having a nice barn to keep the horses and being able to be inside out of the weather while caring for your animals is a VERY good thing.  And having electricity/lights -- ability to see and do at all hours.  With a barn - with a nice wide aisle - you can still work with your horses in some manner in any weather or any time of day or night -- whether it's just grooming or just doing some light ground work in the barn.  AND you can have nice outside spotlights to light up the area around the barn..... there are many pluses to having a barn.  I second the poster who stated MAKE DRAINAGE A PRIORITY!  Pick a high spot - and then build it up more.

We are getting ready to put a 16 foot lean to on one side of our existing barn to make 4 16x12 run in style stalls with 24 foot runs outside of the stalls. The runs will be connected to my arena/dry lot area (I have to use my arena as a dry lot also due to space). It won't be super convenient as far as feeding goes but it will solve a lot of our drainage/mud issues bc we are going to put down screenings/sand and level everything out. As previously mentioned, I'd make drainage and mud control one of your top priorities. :)

This is the lay out of my barn. Sorry it looks like a toddler drew it lol. If I had to change one thing, I'd make the big slider door in the back of the barn a roll up. Its a total pain to try to use in the winter with the snow we get, so it doesnt get used much.

This drawing is what I had on my original property (first barn).  The only difference is that I made feed / tack room combination and I had the location of your tack room an inside wash rack.  The water was in the corner of the feed / tack room for the purpose of keeping lines from freezing.  I never finished the wash rack, but it would be easy to plumb in thru the wall.

Oh cool! That's a good idea. Nice simple layout. I wish the people who built the barn would have scored the concrete. That's actually my biggest complaint. It is SO slick when it get's just the slightest bit wet. Or when you have snow packed hooves on it. Granted, I need many more rubber mats to help prevent slipping but still. Had it been scored it wouldnt be awful.
