I think concrete for the steps would be fine. I think that in the real world a business might spend the money for a stone facade and then use concrete steps because the concrete is much less expensive than the stone. This would be especially true if the stone being used was softer than concrete or prone to a lot of wear and tear from foot traffic. The popularity of hard surfaces for kitchen counter tops causes people to think of stone as hard, but most of the stone used for counter tops is really soft if subjected to a lot of foot traffic.
