Building a building in my backyard for a shop seeking advice

Site $$ Sponsor
I'm getting ready to break ground on a new building so I can move all of my equipment to my house. It will be in my backyard and it will only be for the shop and not a retail space.

The plan is to put in a 200 amp box. It will not be three-phase everything will be single phase but that's fine. Air conditioning and heating will be provided by modular units. We will insulate the walls and sheetrock them and paint ceiling will probably not be finished It will just have spray insulation. I will probably section off part of the building for doing non-shop machine type work. Something with a lot of light and is clean for doing assembly and engraving and stuff like that.

Any positive suggestions would be appreciated.
 
When I built my shop in 2013, I sheet rocked some of the walls and used plywood on other areas. I am not sure how cost compares anymore between sheet rock and plywood, but in hind sight at that time, I wished I had used plywood on everything for ease of moving things around on the walls without having to find studs.
 
Just remember with spray foam insulation if you need to service anything beneath the foam it is a bear, i.e. wiring.

If you are going to use the spray foam I would put everything in conduit and up size it so you have room to pull additional wiring in the future.

I would look the the cost to put in 208/120 VAC service. You can get three phase if needed and you have 120 VAC without needing a step down xfmer.

I would also look at running air lines in copper or the aluminum Infiniti piping. I do not like Sch 40 air lines. I would not use PVC.

With the price of lumber these days I would look hard at a steel building. I'd be inclined to have the pad poured & have someone erect the steel/walls. I'd wire and plumb it myself
 
Make it twice as big as you think you'll need

I've heard this one before. Budgetary constraints are probably putting at about 150% of what I need. I originally started with more than double and have ratcheted back from there due to cost. Since I am self-financing.

Building cost material cost labor cost and everything else have gotten completely stupid post COVID. Honestly I don't know how this is going to continue at this rate. I can't believe what they're getting for concrete. I mean, it's concrete. It's rocks. The laborers probably make 10 bucks an hour through the side door.

I really don't think plywood walls would be cost effective even though that would be great. I was thinking about having all of the electrical done external to the walls and don't put any of them in the walls. Use conduit on the outside and j boxes.

I think I'm just going to continue to use converters for three phase machines. The machine I just bought has a Mitsubishi VFD. The box is super simple and not very expensive and works like a charm. So I don't see a lot of advantage to having three phase in my little shop.
 
I got a 24x40 carport type garage built for around 13,000 I believe there cheaper now. The concrete was other 8,000. I had them insulate the roof then I did the wall and lined my wall with metal roofing. Then ran all my power exposed on the wall in conduit. I don't know where you live but look up carolina carport,Alan's factory outlet places like that and look into too it. One thinh I would go 30' wide if I did it again. But iam going too add a 12' lean-to later on. Mine was built right in the middle of covid reason I think there cheaper now.

At least 10 foot ceilings 12 would be better, You will need to move gantry crane/cranes within the shop for moving equipment around. Don't cheap out on the electrical, Go over and above with wire size, Don't cheap out on the amount of outlets for both 110 and 220, My first shop had very limited amount of 110 outlets and only one 220 outlet I now have 8 220 outlets in my new shop, make at least 2 of them 50 amp circuits, the others can be 30 amp. I have 30, 2 gang 20 amp outlets in my new shop, Install Hall switches so you can turn on and off lights from either end of the shop . Put each bank of lights on separate switches so you can save on power if you are not on that end of the shop. Use all LED fixtures throughout. Run DOT Truck air line 5/8 in the ceiling and drop out down the walls in convenient locations using manifolds with shutoff valves and air drains at the bottom with water traps, Don't cheap out on that either, put as many as you think you may need in the future, and use hose reels, It makes your shop much safer, Keeps tripping hazards to a minimum. Also add your air filtration system at the same time. Have as much insulation as possible sprayed into the ceiling, Don't use batts. Run data cabling Cat 6 and cable to your office. And also in the office put in fast charging usb outlets, They aren't that much anymore. Also, Place the shop near the house, It makes it nicer in cold weather/snow etc to walk to the house quicker.

I can't think of anything else, I'm sure will think of more later, I am sure others will chime in. When I did this second shop I told myself, I have to get this right I don't want any regrets, Itt's a lot of work to go back and redo something you didn't think of or overlooked, Take your time and think everything through.

Edit: Do not run your air system in the walls, I made that mistake when I built my shop, Like I said, run the air lines in the ceiling and use drops in convenient locations, when you are done have your insulation sprayed over top of them. I had to do that retrofit after condensation built up in my piping in the walls and the subzero weather broke the pipes.

Also build a compressor room and insulate the walls and install vents. Put your compressor switch by your exit door, It reminds you to turn it off.

My current shop is 30X60. Bigger than I need but I wanted a way to get my money back out of it. It has a 16X30 dirty area with a garage door. Blast cabinet, Cerakote booth and oven, grinders, disc and belt sanders, etc. are all out there. I built it as a 3 bedroom, two bath house on a 5" slab. All finished sheetrock, I finished the master bedroom and master bath. I ran air overhead and have two runs of conduit overhead with a 4 gang box every 8' so I can place small equipment anywhere I want and have power available. Here's a view from where I'm sitting now.

I too am planning a new building. The one I'm in now, behind my house, is all wood construction and was built in about 1965 or so. I actually have two out buildings. When I bought this place in 1996 I was travelling nearly 100% of the time for years on end and I was single. One result of this is, carpenter ant damage. It could be repaired of course but I do want a bigger better shop and I'm considering a steel building. I have since gotten married and the biggest hold up on the shop is I have an above ground truck lift that needs 15 feet overhead and the wife won't sign off on the added expense for a building big enough and tall enough to accommodate it. Her thing is, get rid of the truck!

So I've seen you're planning on getting married...:)
 
For a new building interior and ceiling, you should really look at white powder coated corrugated steel sheeting. It's cost effective and bright. The race shop I work in has it and it's great. He's finishing a new building now that will house a 5 axis machining center, water jet and other fab equipment...that got the same steel sheeting inside.
 
Build a "dirty" room, for sanding, grinding, etc. Fans and ventilation.
I have a 45 foot container with my Bead Blaster, Parkerizing tanks, Parts washer, Hydraulic press grinders/buffers and sanders. I ran pex underground from my air compressor room to the container, also put an air hose reel out there and full electrical and lighting and a 60 amp welder circuit and plug.

I forgot to add: Make sure you run plumbing to the shop with a good sized wash tub and a hot water heater.

My fiance wants me to have a badass shop. Moving machinery is not something I plan on doing very often.

Yep thats the type of metal I used on the inside of my building
