Day 18, installing the substructure for the drivable grass:
Day 19, sod is in! They worked so fast I didn't get a picture of filling with soil. The soil is packed into the spaces of the support structure, and the sod laid over top.
Our hope was that replacing concrete in this area with the drivable grass would reduce the temperature in the back yard, and it seems to be working. Yesterday's low 80's F temperatures would previously have made this part of the yard unbearably hot. With the grass it was still warm, but tolerably so.
Bonus pic, nighttime lighting in the back. Now you can see what those posts were for. Cable was strung across to hold overhead pendant low-voltage lights. We've planted some trumpet vine that will also grow up the posts and across the cables. Look at the nice pattern the lights make on the wall!
(We're keeping the furniture covered until all of the work is done.)
We're down to finishing touches now, and should be mostly done by the end of next weekend. I'll hold off posting any more pics until all of the landscaping is done. Whew!
