Charles at $30/sqft I would jump on that deal. Ten years ago I built my 24×30 metal garage on slab for a total of under $12,000 or around $16/sqft. I, and one helper, did the labor and saved quite a bit. That said, I think your $30/sqft would be well worth it. And boy do I empathize with all the accumulated aches and pains… ;-)

Mike, a couple of people around hear have told me that price is a about right around here. However, I'm no longer have a choice since I can't do it myself any more. Unfortunately, this house we're moving to has a nice full basement. However, my insurance agent told me that if I put a well equipped shop in my basement it would be a risky move if the equipment ever caused a fire. I'm taking no chance on insurance and will make it a stand alone shop with it's own electrical service.

A few years ago I had my son, who was trying to get started in residential construction here in Iowa build a
16 X 20 addition to my existing garage. I made sure he did everything that he would do for any other customer and
not "favors" for his dad! I did the wiring myself. This is legal by code here if you pass a test as a homeowner.

Anyway with the construction of an addition to the house itself, which this was, we had to meet all the codes applicable to house construction. The result was a total cost of about $16,000! Oh! I also did the painting of the walls and the floor. Major expenses resulted from having to move our electrical service cable, which is underground and foundations below the frost line, even for a slab floor. I have a really great shop that could be used for other purposes by someone in the future. Naturally, it is too small but this was as large as I could get and still meet the setback requirements in our area.

A stand-alone building would be considerably cheaper but has its own problems of course.

We just completed a 15×30 garage for a client here in western Colorado. We did dirt work, concrete, frame and finish. Materials only on this project were approximately $18sqft, lumber and concrete. So for you project in our area it would be a little over $4k. BUT this was for pre-enginnered trusses and if you can get a project approved in your area for a hand built roof system that would save you a bit of cash.

Looking at your plan link. If your in a low snow area, you could save money with a lower pitched roof as well.

I've seen adds from saw mills in my area for lumber that is a bit less then my lumber suppliers. Typically this lumber is a little more wet and prone to warping. Attached is one of those adds for info reasons.

I have nothing to do with this company or have never purchased from them..

I'd like to suggest that you consider vapor barrier in the slab and condensation guard on the roof and walls if you are using metal siding/roofing. I don't know the conditions where you are but I have seen many budget metal buildings that are condensation traps. A cool evening after a humid day causes rain to fall inside and framing to get wet. A little rain is okay on a tractor but it would suck on a table saw. IMO it's cheaper spend now than fix this after the shop is built. Good luck. -Jack

I built a 16×16 shop 2 years ago. I did all the work myself and it cost me 6638.xx. Give or take a few bucks. I kept every receipt I had, everytime I bought a nail, or a screw. I'm sure I missed a few receipts. I didnt pour a pad so have no clue about that cost.
Of course now I wish it was a 40×40 and I would then wish it was a 100×100

Might want to check out this thread by a guy drawing up plans to build a workshop in Pacifica.

The only way to answer this: Draw up plans, make a materials list, and get quotes. I don't think you can do it for that cheap, but you may have a line on reclaimed lumber and cheap concrete. And get a few quotes from prefab places too, doesn't hurt to have comparisons to the steel awning/car port and the prefab shed folks.

Take your plans to the lumber yard in your area and ask them to do a materials bid. If your useing trusses get a bid for the trusses from your local truss company(check yellow pages), figure out how many cubic yards of concrete your monolithic slab or, foundation and, slab will take call your local concrete company and, ask them how much for haveing that many yards of concrete delivered also can a concrete truck drive to your shop location if not than you will need a concrete pump truck just another call for a quote, add all these numbers together, and bingo bango bongo thats how much it will cost to build. The question your asking can only be answered by the frase "it depends on what the material costs in your area are" also how much work are you going to do yourself, framing, concrete, electrical, roofing, and anything else that you want to put in this shop footprint hope this helps.

2000 won't be enough. Especially if you pay to have a slab poured. Even on a pallet and pier foundation .2000 likely won't do it.
If it were a pallet and pier than 2000 should get you well under way though.

Also depends on what kind of materials you use and how good a deal you can get on those materials. After the slab foundation is paid for, I would think another 3000 dollars roughly to build a 12×20. Somewhere in that neighborhood.

IT will take 2.75 yds of concrete if I didn't make a mistake. No footing just a floating slab. I think they do that where you live. Call the concrete place and see what they will want for that delivered. Check with some big box store that sells kits. That will give you an idea. Add $500 to that price because you can usually cull you lumber if you buy locally. Worth it too. Check on permits. Get an estimate from an electrician. Now get ready and go to work.
