first plan looks good to me charles

easier roof to build
and more storage space overhead

can’t say much about the prices in your area

do a read-off off materials
and find out how much delivered cement will run

all this will be good for you
as this is what you will have to do
for future work

most lumber yards have estimators
and will give you a bid on materials
(how i found the best prices for my house)
when you get your plans
have them copied
so you can leave a set with the suppliers if needed

are you getting a permit too
you will need some for them too

the best in this
good to see you are still moving forwards

You could probably throw the structure up for that, but you would have to figure extra for utilities and the slab, which already have figured out, not to mention finishing the interior (insulation, outlets, lights and wall covering, etc.). A 9×7 roll-up garage door will cost around $250-more if you want a fancy insulated one (a good idea if you need to heat your shop in the winter). Which brings up another point, are you going to install a heating system of some kind? Hope I’m not totally dashing your dreams, I just know how fast these kinds of projects can add up.

p.s.-I’m still jealous!

One of the most important (if not the most important) function of a contractor is estimating. Learn it well.

I doubt you can build it for that price, but like Patron said, get your material cost. Do your own material list. I never found a supplier to be accurate.

That won’t cover concrete. Here that’s about $105 a yard. My guess is that the building alone will be double that.

Buy a book for wiring. It really isn’t very tough.

I agree, running the wiring isn’t very hard. Maybe hire an electrician to terminate both ends if you’re not comfortable doing that. Might want to check into the permitting, as they will be able to provide more guidance for you.

Hi Charles
As a long time contractor I think your price is to low. To start with when you build a garage/shop you need more than just a flat slab to build on you need footings all the way around the perimeter in my area code requires the footing to be a minim of 16” wide by 8” thick that adds 3 yards of concrete plus the 3 yards you need for the rest of the slab , Then you will need rebar ,sand and or rock. I estimate that the concrete plus the other items for slab using the cost you gave for concrete in your area. This will cost from $800- $850 with out any labor to help form and poor and finish the concrete. Then you need material for framing.rafters , material for sheathing,siding, roof sheathing, felt,3 tab,material for trim, windows ,doors. All together if you don’t pay for any labor I would guess you will have $2500-$3500 before permits,electrical ,insulation,plumbing. You may prove me wrong if you already have some material or can use some used material. All said and done for only a little more you could have a shop twice that size. I know a 12’x24 is better than no shop but you will be surprised how fast even a 24×24’ shop will fill up. Good luck on your build. I would be more than glad to help with any question ,just shoot me a Pm.

From your Web Site...”I have a degree in Building Constuction Technology”

As Don said “One of the most important (if not the most important) function of a contractor is estimating. Learn it well.”

From that alone, ..Why should it be difficult for you to work out at LEAST an Approximate Price?

Concrete $80 to $150? Why such a Large Spread?

I’m a Retired Contractor and I could do a Material Take Off List from the Plans and from that plus all the other extras i.e. Electrical, Permits, Drainage, any Sub Contracting figure out a Price in a couple of hours.

You have a Degree as above. You can or should be able to do the same.

Off the top of my head …. $2,000.00 MIGHT cover ALL of the Material Costs ONLY.

If you do the Electrical Yourself and NOT a Licensed Electrician with the Proper Permits and Inspections and something like a Fire occurs later. FORGET about any Insurance Coverage you might have. It’s Null and Void.

So. Sharpen your Pencil. It ain’t “Rocket Science.”
