I just don't think there is any more dramatic way to make a statement on a doorway than to use big natural edged slabs. These kinds of stones are more laid back than your traditional sawn and flamed, salt and pepper granite steps. They also have a lot more wow factor to them.
The steps below are from a house in Maine near where we harvest these kinds of stones. I like the look for a front entry way as well as off the back onto the patio. What do you think?
