These are usually installed on the front or side entrance to your home. They can also be a way to transition grade changes on your property. Steps that are built attached to your home, will need to be anchored to the existing home foundation and supported on a poured concrete footing below the frost line. How much of a footing is necessary depends on the quantity and weight of the structure. Steps consist of the treads (what you step on to transition from one grade to another), the risers (the vertical area of stone/brick under the treads), and the two sides of the steps. Bluestone, granite and limestone are the typical treads used for these designs, with bluestone being the most common because of its cost and durability. Fieldstone and bluestone are the most common choices of stone for the risers and sides. They can either be installed as a stacked stone, mosaic or a custom blend of the two.
