We built this on the weekend! Amazing family effort. The kids wanted to be involved in the building and filling, it was handy to have some ear muffs and gloves for them to wear.
The garden bed was designed to be 3x3m square and 0.4m high. Due to the slope of the ground, only two sides are the planned height – 2 sleepers, and the other two sides are 0.2m – one sleeper high. Enough materials left over to build another smaller raised bed, 2x1m large, 0.2m high, which was also completed on the weekend.
The raised bed was designed to use the full 3m length sleeper to avoid wasted off cuts. The post holes were dug 0.6m deep.
Materials used include: 8 x 3m sleepers and 3x 2.4m posts, 150mm bugle head screws, 3.5m3 premium organic soil. Total budget: $370 – a big investment!
