The wall is inspired by artist Richard Serra, we love his work, and by our strong desire to create and move on and leave it, literally, forever. No rotten fenceposts, no yearly staining etc. We are developing a creative love affair with rust. It has always been, and always will be with us so we might as well utilize it.
The upper arbor is made from steel salvaged from our local scrapyard. The posts have salvaged rebar interiors with cinder block exteriors and are then filled with concrete. The patio blocks are poured concrete.
When we were building gardens, professionally, many jobs consisted of replacing wisteria arbors. Left unattended wisteria can literally (we saw this) take down a house and at the very least, they dismantle the structure built to support them. With steel and concrete that should never be an issue.
