I currently have a 4' crawlspace w/a dirt floor. My house is 25' deep and 40' wide, roughly. The main beam is about 12 feet from each wall (front and back). Here is my stupid idea: I would like some type of below house storage and a better place for my washer/dryer/water heater/furnace/etc. Can I just dig down another 4' in an 8' x 15' area (away from the foundation) and just put in a concrete floor and use some forms to build up some walls to hold back the dirt? I would then probably just frame some walls (about 3-4' to the existing floor joists) above the formed areas. THis would basically let me move my utility room to a basement and allow for some needed storage. None of the existing pipes. electrical, ducts would be moved (except to reconnect the appliances) Heck, I would happy with only 6' of headroom there, for as often as it would be used. Like I said, my dumbest idea ever: but is it possible, if I am patient enough to dig the darn thing out? Heck, I rewired the house, upped the power from 60 to 200A, ran 100A to the detached garage and wired all of that, redid the walls in the house, gutted the bathroom, among other things. Other then moving dirt, this should be manageable. right?
