So i have a potential customer that wants us to add a addition to her existing concrete patio. We are to add a wall, paver patio, with a fireplace. No prob. I've done this. But she wants us to do something on top of the existing patio so i t will "blend" better with the new. what do I do? She only has 2 1/2 to 2 3/4" step into the house from the existing patio. she will not tear up the existing concrete as it already has footing under it for building a 3 or 4 season room over it down the road. the new patio we will build will be a couple of steppers down following the natural slope of her yard. we are in Northern IN so we are in the winter freeze area. Thanks in advance.
