Pole Barn Ideas

FYI, I'm a little wary of putting foam under a pole barn slab unless you are going to trench in a perimeter footing and insulate that as well. Without the building heat to warm under the slab, frost can creep under the perimeter and start pushing up on the slab. This can wreak havoc on the building.
This is unlikely to happen
 
you have to wrap the entire grade beam with foam, then just put flashing over it on the exterior to protect it..same as we do houses
 
If you can afford it , better to build it bigger NOW , everyone I talk to wishes they did that. I had a 3 garage door pole barn built in 2004 , wish I would have made it bigger with 4 garage doors , and looked into putting a 2nd floor inside for storage.
 
The builder and I talked about insulating under the slab and we decided not to do it. There will be a vapor barrier under it but with how I’m going to use the garage and what temp I’m going to keep it at in the winter I would not see the return in my investment during my lifetime.
 
Do you mind sharing the estimated costs for this build @Peeps ?

Quotes have been far and wide ranging from a low of $120,000 up to $185,000. This does not include electric, plumbing, heating, or a concrete pad out front of the building except for 1 that did include the pad in front of the garage doors. The majority don’t include site prep either. The big names ie Morton and Walter’s were near the highest. There are also variables in the quotes like the amount of insulation and gauge steel. Only 1 place came out to see the site and sit down in person with me to see what we wanted. They are who we are probably going to go with.
 
If you aren't on a pretty level sight, don't forget the cost of fill to level the floor. It adds up in a hurry....
 
I built a 40x48x16 with 12’ wide lean-to’s down each side, and enclosed the back 12x12 section of each back in 2015. Also planed to do a mezzanine and a 2 post lift. At the time I was younger, tried to save money and thought I would finish things along the way. Here’s my regrets and what I would do different.

Regret # 1, I let my contractor talk me out of doing either perma columns or a traditional foundation with their wet-set brackets. He convinced me wood posts backfilled with dirt would outlast me. Told me it would be 10k more to do a footer, and I cheaped out. He did do a nice job with grade. It looked level when we cleared the trees, but he told me
We had to raise it, so we brought in 6 or 8 tri-axles of pit run and it sits perfect now.

Our driveway and under the lean to’s is millings, and in the next few years I’d like to concrete under there and pave the driveway. maybe the post will outlast me? But I’m 35 and don’t want to deal with rotting posts when I’m older, so I may look into replacing them with perma columns soon. Also, if we do concrete and asphalt, replacing them in the future is gonna be horrible.


Regret #2, thinking I’d finish everything else myself over the next year or two to save some money. It took me 5 years to run electrical out to it, and the only light I have in there is a large plug in led parking lot light that I have attached up in one corner. It is still a shell, with outlets. No insulation, no hvac, no lighting, no mezzanine. I wish I wouldn’t have been so cheap and did it all when I built it. It will probably cost 2-3 times more for me
To do it now versus then. Circling back to replacing the posts, since the inside isn’t finished except concrete floor, I figure now would be the time to tackle that


things I’d do different

going a route with no posts in the dirt. Wether it be traditional foundation or concrete piers w/wet set brackets or perma-columns with their concrete skirt board, no wood touching dirt is the ticket.

Finishing everything when I built it. I have lost out on a decade of good barn time since its like a deep freezer in the winter and an oven in the summer.

The windows up high for light is good, I wish I would have done and will be doing before I finish the inside.

Get a price or two for standard stick built, and avoid any wood contact with the ground. Your older self or future owners will thank you

If think of anything else I will post here, but congrats and good luck
 
I agree perma columns are a must and keep your wood away from the dirt. I have a friend who ran in floor heating for the future. Once he finally got around to finishing that I was amazed at how cheap his system is and how comfortable his shop is in the winter. The meat of his system is a tankless water heater and a circulating pump.

Plenty of videos on youtube showing how to replace rotting pole barn posts. Doesn't look like a whole lot of fun and probably very expensive if you can't do it yourself!
