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.

 

I am going to build some carriage doors. I dont like a roll up garage door. I wonted to do a hip roof garage but I can do one of those. I will do my own material list. I was taught how to figure materials.

 

"I am wondering would $1000 to $2000 build a 12×20 garage workshop."

Not if you want walls.

 

Well I am going to all the work, expect for the wiring.

 

i dont no about where you live, but hear you can by a pre built cheaper then you can by the material to build one.
you can buy some pertty hi end pre built pertty cheap.

 

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.

 

Concrete here is $80 to $150 and yard. I live in Alabama so our building cost is not to bad.

 

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.

 

I thought about pour a floating slab for the garage.

 

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.

 

Ok thanks Jim!

 

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."

 

The "spread" on concrete pricing is because of what goes into that yard of concrete. 3000, or 5000 psi? Air entraining? High Early? How much Calcium was added? Did a 5 yard driveway aproach a few years back. 4000 psi, 5" slump, and it costs about $735.

How thick a slab? Can it be poured as part of the foundation? Aka: Thickened slab? In addition to the rebar/mesh, would need a supply of anchor bolts as well. Keeps the building ON the slab.

My "Degree"?? 6+ yrs as a Concrete Carpenter, Commercial.

Might want to add one more zero to that estimate of $1000…...more like $10,000

 

Let's not beat the crap out of the guy now, shall we?

 

I have a 32 by 40 shop and it's too small bu 24×24 would be a good size with a shed for wood storage

 

We do 4'' slabs here.

 

Wow prices have gone up!

My tri-level 2,200 sqft house, with AC, and 30, 000 sqft yard only cost me $28,000, in Illinois ….. 40 years ago!

Just kidding, this is my reality check!

I have priced an outbuilding of about 2/3rds that size at $12,500 w/o AC in silicon valley … but we have some special earthquake codes.

 

Milo: "Let's not beat the crap out of the guy now, shall we?" Sorry! Are you a Moderator on this Site?

He asked a Question and He's geting Answers. Simple as that. Now back to the Post at hand.

I got out some of my "Quantity Surveying Software" and hit a couple of Sites I've used in the past.

If you do a lot/most of the work yourelf with a Gable Roof, Regular Siding, Doors and Windows, and considering it will be used as a Workshop it should run in the area of $7,200.00 or $30.00/Sq. Ft.

That does NOT include Site Preparation, Any Sewage Work, Plumbing to the site, Electrical to the site, or a Driveway.

If you have it done by a Contractor it would most likely be in the area of ….. LOW: $40.00/Sq. Ft. or $9,600.00. More realistically ….. AVERAGE: $55.00/Sq.Ft. or $13,200.00

Both figures could be altered a fair bit, depending on your Local & State Requirements.

I'll stop now.

Good Luck on Your Garage!!!

 

Go to one of the big box stores (here they are: home depot or lowes). See what they have in a prefab shed kit. Here in Saint Louis anything over 200 square feet requires a full foundation, hence my garage expansion was a 12×16 barn type shed attached to the garage. I later removed the common wall.

 

I have built my workshop a few years ago, it was 19' x 10', and I built an extension this year (you can't have enough room!), it was 11' x 10'. But I f you say that $2000 is enough, then multiply it by 2. Then you might be closer!

 

I built my new shop about 3 years ago. I did all the work myself except for the excavation, which was about $1000. It cost $36/sq ft. Its not quit finished inside, but that should get you close. You can see it in my workshop section. Even at half that cost you're double your price.

 

Price is too low.
Reconsider the size and build as big as you can. There is never enough room.
