What installation issues do you see with this project? The house was built 18 months ago. The owner is taking the topsoil out bringing new topsoil in and sodding. He may put irrigation in but not sure. He needs a step off the sliding door. From the door to the ground now is exactly 24" and it is exactly 72" wide. I was thinking of 2 8" steps with the Wright Frames system. The patio will end before the downspout and will be about 3' past the dining room area that sticks out further. On the corner by the step he wants a 12' diameter circle kit and the center to be at the corner. The circle will have a 4' table and chairs on it. He wants to have the circle "blend in" with the patio so its a soft turn and not a 90 degree. Using the EP Henry COV I or Old Town Cobble in the "I" pattern for the patio and the circle kit for the circle. Dimensions are Patio: approx 18' long by 10' wide Circle 12' diameter Steps Total of 16" in steps and 72" wide. Cant get pics to load right now. They are too big. Will try to post them asap. Thanks for any help.
