Options for a two-story garage

Hello all,
I know I read a post on this subject, but after spending a couple of hours searching and not finding it, I thought I'd ask outright.
Background: We have a small building on a site where we would like to put a garage. It is on a slight bank now which has eroded quite a bit underneath the building. The current foundataion (combination of poured concrete and posts on blocks) has begun breaking away. The framing for the building is solid and will be salvaged, but the building itself will be razed.
Project: What we would like to do is build a new garge on the same site, but instead of up on the bank like it is now, we would like to open up the bottom to make a new home for the Yanmar, mower, etc. Then the "main" floor would be a two-car garage/shop. We were thinking about using poured or block walls for the bottom level and a reinforced concrete ceiling/floor between the levels. Then a stick-build main floor. The building itself will be somewhere around 24'X30' (give or take)
Questions:
1. Do you know of any pros/cons to using block vs poured concrete for the bottom floor?
2. Is having the floor between the level made from concrete going to be an engineering nghtmare?
3. Should I consider a steel building for the main floor?
4. Would you suggest another approach?
5. Does the fact that the current base has eroded give you any concern?
Sorry for the birrage of questions. We will get an engineer to work out the details once we decide more clearly what we want to do, but just wanted to solicit some opinions first. Thanks in advance.
-Frank

Most of my house is concrete, including the 'main floor' floor, which is above a full basement. Suspended concrete floors are certainly doable.
A suspended concrete floor will be expensive, one way or another. Your choices are open web steel joist, galvanized corugated pan, or precast. You can get big (like 40' plus) spans out of OWSJ, but its expensive as stink (half the cost of my whole house!). Pan is chearper buy has limited span, but if you designed in a supporting wall or a major steel beam you could get away with it. Precast I don't know about but is probably midway.
The whole project will have to be engineer stamped, if your codes are anything like mine.
And yes, you had better get the erosion under control with a retaining was system of something first. All the construction activity would likely make it worse rather than better.

I remembered a similar post too I just recalled also that it was Von who has a two-story garage. Here is Von's Post over on TBN where he describes his garage.
Hope this helps.

Thanks, that helped. I followed that thread and jumped over to another one that was similar and found all I needed. Appreciate the memory jog!
