As mentioned by Trueblue1234, McMonagles have a 'Stoneer', which is basically a veneer of real stone facing .... so when it's on, you cannot tell the difference. I did a porch and sunroom in full stone as they didnt have the stoneer option at the time, but if doing it again, would do it in stoneer, much cheaper and same effect. I love natural stone on a house. Have a contact for a brilliant stone mason based in the north but he seems to work everywhere, if you need it, PM me.
