Steps
Step 1

Started by laying out the house lot of windows I won for $1 on trade me, made a rough plan. Put my 4 posts in then prepared the base for the pavers.
Step 2

After the windows were all in place I found some hardy paneling on trademe that I won for $15.
Step 3

Started to make a self watering garden that catches water from the roof.
Start by laying Nova flow down with the end enclosed, covered with stones until it reached the overflow pipe. Laid cloth down that will allow moisture to wick but not let soil get get among the stones cover with a layer of sand then soil
Step 4

Set up another two smaller watering bed before planting
