What Does a Stone Driveway Cost? Depending on the choice of stone and the depth of the stone and gravel base, plan to spend $1 to $4 per square foot for a stone driveway. You can keep the costs to a minimum by doing much of the work yourself. How Is a Stone Driveway Built? A new stone driveway requires that the sod and topsoil be removed, and the surface needs to be graded. Depending on how much stone and gravel you plan to add, you will need to dig at least 6 inches deep, and preferably 10 to 12 inches. Compact the soil, then add a 4- to 8-inch gravel base, topped with 2 to 4 inches of stone.
