Well...I've already did two walls this year and the one was half this size and took us two days. So...I'm guessing this will take four days from the time we run around for all the supplies to the time we back fill and blow off the driveway...crew of three...eight hours a day. Yes, they were huge in the 80s and it seems to be a lost art. Not many people want these now with the popularity of the black walls. However, I get calls to do them every year. Just want to get some feed back on pricing. I've made these walls with curved steps, built in benches, planter boxes. I think they look beautiful and give a softer feel to a retaining wall.
