Hi, Plan A was building the Garage with no Basement, instead we would have to pour a 10' High(at highest point) to approx 2' high, 47' long Retaining/Foundation Wall. This wall runs beside our Driveway that goes into our Basement Garage under our House. In addition there was "Stepping" under the building on 2 Sides. Meaning...lots of forms, concrete & rebar. You can only imagine the quotes we are getting back! I've had 5 serious spine surgeries, am in a wheelchair & need to build something so we can get out of the rain & snow. We need help with Plan B: How would we build the same Garage(24x24), but instead of the large Poured Retaining Wall, which 1 of the Garage Walls "would have" sat on, Could we just build a "Block Wall Basement"(4 walls, not 1) & make use of the space underneath? If we can do this using Block, what material do we build the FLOOR out of, "Prestressed Concrete Floor Planks" or is there a cheaper, but safe & sturdy way to do this? We are over budget with Plan A. We need to build something safe and something our Township will approve. Our thoughts are if we have to pay a crazy $ as we've been told, why not spend the same amount on something that gave our Home more value & a place for my Husband to have a Workshop. I live near Hershey, Pa & need to find potential contractors & suppliers for the materials. Thanks.
