has to have a foundation for the weight of the addition,
dig your trench for the foundation, down below the frost line, pour at least 6 inches of cement, then lay cement blocks up for the foundation height,

Like above, there are methods for treated lumber foundations. You would have to check with local building officials to see if permitted.
But also like Doc, how is the existing building built. Maybe you price it both ways, but my thought is there won't be much difference in price as percentage of the entire addition cost. And the concrete foundation will be superior. The best value will probably be a footer, block wall, slab, if the grade is relatively flat. Sure you have the price of 2 yards of concrete and finishing (17x9=153 sq.ft, for a 4" slab divide 153 by 81=1.888 so 2 yards) but you don't have as much excavation, you don't have a floor system of joists, decking, etc. Check with the building department, they may even let you do a monolithic slab. The footer is integrated in the slab, and there is no block.
If you do go with a slab, and your house has a floor system of joists and decking, you will have a step or two down to the addition, but it will still be the most economical way to go.

I just answered a similar Q, and with all due respect, you might have added some details.
Part of your issue and desire, depends on not only the fabrication of any addition, but how the current stucture was fabricated; the foundation and/or slab/crawl space, and other issues such as permitting, codes, zoning, etc.
Even without not having money for concrete, we, here, can only offer vague suggestions without details.
IF by some ability, and within ordinances you could build without a foundation/slab/crawl space, you would have to have some means of GROUND support. Obviously William offers one suggestion/option that is valid, but takes concrete.
No offense meant, but ANYTHING you use as a support structure would probably equate in costs to concrete.

An addition about that size is going to cost you roughly $150.00 per square foot so, if you don't have the money for the concrete, stop right there and, start saving. Your looking at 20 to 30 thousand in building.

It sounds like building out the back would be the best. You could even make it into a split level house. We had one in Denver and it worked out very well. I know you have a limited budget but it might be worth your money to hire a architect or builder for just a consultation to help you with the decision.

Treated wood foundations are an option. They are supported on stone/gravel base. Call local building official to see if it's permitted in your area.
