When designing and planning your house addition, you will save a lot of money by building it with a slab on grade foundation instead of a basement or crawl space. Eliminating a basement eliminates excavation. Building over a basement will still require a concrete floor and walls made of block, concrete, or brick. Building over a crawl space requires post setting, footer placement, beam construction and framing, as well as building a skirt and installing an access point and installing vents. Building your addition on a slab on grade foundation is simply a matter of framing and pouring a concrete slab and erecting the frame on it. You will save on lumber and other materials, as well as labor cost. Building on a slab rather than a basement or crawl space can save you thousands and even tens of thousands of dollars from savings in labor and materials.
