Concrete house

I was wondering if anyone could lend their input as to how much it might cost to construct a simple house, around 800 sq. ft. out of concrete.

I'm just looking at my options, to build an energy efficient house.

Thanks

How much does a car cost?

Can you narrow your vision down a bit?

Sure I could narrow it down, but since I was looking for a general answer, I didn't want to get too specific.

I want to build an energy efficient house out in the country. Nothing too big, like I said around 800 square feet.

Possibly a berm style, covering all but one side with soil.

What else do ya need to know? I'm just looking for a real general ball park answer, to see if it's even an option I could consider.

Thanks for any help.

From where you are Mid-Michigan Id say forget it. I have had cement homes down in Fl and they work very well. Even had one with a R28 cement walls

But the main thing up where you are is the hot to cold there is just to much expansion and contraction. Blocks might work but then you have to fur out so you can put lots of insulation in so the cost will go up. Have you looked at a 2X6 stud with a R19 insulation in the walls. Id say thats the way to go

If you are thinking about earth contact home you need a 8" pour on all 3 walls. With studs on the walk out side. face it south

==================

it would cost somewhere between $10k and $300k.

close enough for ya?

if you want to figure it out, blocks are 85 cents each for an 8 inch block (they are 16 inches long and 8 inches tall. Concrete is between 85 and 100 dollars a cubic yard. Figure in a row of metal reinforcing wire every other course and 1/2 inch rebar in every 3rd hole of the blocks and fill them with grout. Put a bond beam on the top course with two runs of rebar and filled with grout.

Yes, I am being sarcastic. There are simply too many variables for somebody to say, "it will cost $xxxxx.xx"

Yes I know there are alot of variables. But I need somewhere to start.

Using your information, I can narrow it down to a range of Forty-Seven dollars (Unabomber style) up to a couple million if you insist on only granite worked by the purest of virgins in the fabled mines of Vinerio type work, etc.

I think the real question you are asking is how does the price of various types of stucture compare.

For a small house built by others:


The cheapest will be a pier and beam of wood.

Next would be slab on grade and wood.

Followed by Stucco over wood.

Then masonry veneer over wood.

Then structural concrete, either ICF, AAC, or CMU.

Lastly, formed concrete, either poured in place or tilt-up

Call someone who does basements and give them the size you want. Say 24 by 32. They could do the estimate easily and at no cost to you. It would be the same as a basement without the digging but would take more bracing so the cost would be similar. Here in IL. it cost me 11,000 for my 24 by 40 basement with 10 inch walls, 3 windows, a stairway to the outside, and sump work 3 year ago.
