.I have a question regarding different heights. How do you know what heights to match up too.. and from what distance? I only ask this because I recently began a project, where a client/friend asked me to extend his driveway, using paving stones of course. He has a concrete walkway that connects perpendicular to his driveway, and he wanted to extend the driveway so the walkway goes straight onto the driveway. What I did was string a line from the driveway street curb, to the concrete at the width he decided he wanted.. My problem is, that when I string the line, the outside edge of the extension ends up higher than the driveway, because the line I've strung goes from the street curb to his walkway to his house... which slopes up perpendicular to the driveway.
My question is... would I have been better off using the driveway height for the entire extension, and then sloping the extension to the walkway closer to the end?
Hopefully this isn't too confusing, not sure how to include a picture.
