I just built a 20' wide by 27' deep attached garage with 10ft ceiling. 2x4x10s were used for the walls. The footing has to be 3ft. deep 8" wide i believe. My footing is 1ft taller than planned giving me 11ft ceiling now. against the house is fireproof Sheetrock by code so fire cant spread into the house. I used a 16x9ft garage door in the front and i put a 9x8ft door in the back so i can pull my trailer into the back yard if needed,also for air flow. a man door on the side.
Material cost for the framing this includes the roof was around $3,000 and i used 5/8 osb for the outside walls and plywood for the roof( they gave me plywood by accident). -I payed good friends to build it about $3500.
-I needed siding,gutters,and any other miscellaneous material for the exterior which cost about $3000. I was able to use some of the old siding too.
-garage doors, insulated doors with openers and installed about $3500.
-to finish the inside i used 5/8 osb on 3 walls(ceiling at the moment is still open) cant remember what that cost...$10-12 a sheet maybe?
-for lights i used (4) 8 ft t5 fixtures giving me 16 bulbs and 4 fixtures, about $320 plus the light bulbs...another $120? (freakin expensive but they come on at -20 degrees and are bright).
Then my other concrete work which was a pad under my deck in the back yard,walk path to the garage in the back yard,steps in the front,and a 3 car driveway.
Round about price in all $23,000. The concrete in the garage has fiber glass poured in with it and steel. The driveway has the same. the other concrete just has steel.
i know 27 ft. is a bit odd but my i want to be cemetrical with the house

 

Sounds like a nice garage.

One thing to be sure of is to check with the building dept. on how deep you've got to go. Up here, because of frost, the foundation has to go down a minimum of 48".

 

Planning too stick build the roof trusses, we are not wanting to spend a lot, we've got a lot of strong backs, not scared to get a little dirty

But compared to some of your garages, you might call what we have in mind a shed


btw 1 post away from 400 YESS!

 

thanks moosehenden. I think for my area it was 3ft. for my area.

 

btw here is the floor coating i'm looking at.. don't know if i should shoot for it... concrete has gone up....

My garage floor is cement with a coat of gray garage Paint. I'd end up destroying (or burning) anything other than cement.

 

rhino liner does the same thing and is actually quite nice, Cant burn,scratch,cut,ect...Same warranty as a bed liner basically. If you get oil on it it wipes right up with out being slick, so the dealer says anyway.

 

I've had rhino liner on my truck beds before- it's ok.
it does chip and it will burn if you're welding over it.

can't imagine spraying a garage floor with rhino is cheaper then pouring cement.

maybe I'm misunderstanding what you're looking to do but-

there's no way buying 2x10 or 2x12 floor joists & 3/4" plywood and then finishing off a 25' x 30' garage floor with rhino or some other garage flooring is going to be cheaper than pouring cement over a load of crushed stone...

if you figure about $50 - $65 per cubic yard of cement- for a 25' x 30' floor 6" thick- you'd need 14 cubic yards of cement for the floor- not including the footing (+5% error included) you shoud be looking at around $700 - $800 in cement. Factor in a dozen 2x10's and some plywood for footing forms, a load of crushed stone and an extra $500 for footing cement and you're under $1500 for a cement floor (with 3' footings). It doesn't get cheaper, easier or more durable than that!

I poured an 8' foundation with 10" thich cement walls, (not including the footing which was 30" wide, 12" thick around the whole garage and a 25' retaining wall also 10" thick, 6' tall) and a 6" thick cement floor for a 26' x 26' garage- cost for just the cement was only around $3k (was double that for the framing crew to set up the forms)- there's 4 times more cement in the walls and footings then there is in the garage floor.

I say go with cement and be done with it.
