My husband & I live in a country-style, one-story home with unfinished attic. It has a crawl space foundation and sits in a fairly flat area which was previously pasture. We are above the water table and live in the South. We would like to explore the possibility of adding/excavating a basement beneath our existing home. What warnings, suggestions and expectations can someone provide on a job like this? We are concerned about the cost, possibility of damage to our home's structure, etc. We really have no idea about how to begin gathering information about a project like this. We would greatly appreciate any and all information anyone might be able to provide. Feel free to e-mail me directly at firstname.lastname@example.org if you like.
