I took this photo in Halifax on Monday of a tree surrounded by two stone walls demonstrating two very different treatments of construction. The wall in the background is what's called a gabion wall. The stones are held together inside wire cages
The foreground wall is a simply traditional dry laid wall. It utilizes stones held together by the virtue of the way they have been skillfully fitted together.
The builder employs the elements of mass and friction and the unique shape of every stone to create a solid immovable wall. Which wall looks better? Which wall will not rust? Which wall has less manufactured material ? Which wall will require less work to repair?
