How To Expand A Basement

A basement can be expanded in a number of ways, most of which will involve some degree of remodeling. One option is to add on to the existing structure, either by digging out more space or by building an addition. Another option is to lower the floor of the basement, which will create more usable space. This can be done by excavating the soil and installing new supports, or by using a system like PolyLevel which raises and lowers the floor without excavation.
