Concrete Pathway Is Growing

The concrete pathway around the house is growing. To date, it's encircling the house  3/4s  of the way. What you're seeing in these pictures is the path wrapping around the back. The steps and railing are coming from the side of the house near the rear. The white pipe running under the concrete path right now does nothing, but in the future will carry the greywater from the kitchen to a banana patch. (I'm actually thinking agead! Time to run the pipe is now rather than later.) 

The pathway balloons out into a patio. The idea is to have a small table and chairs here. Right now you can see the seams from the individual concrete pours, but I know from prior experience those seams will disappear from view as the concrete develops a darkened patina. 

Here's a view looking from the other side. The white pipe in the foreground, like the other pipe, presently does nothing. But in the future may handle the greywater from the bathroom, again going to a banana patch downhill.
