I love the metric system!
Thanks for the advice.
Depending on the soil strength and with a small 'footprint' like this you maybe could go with less border but those calculations are beyond me.
The metric system is superior. I've heard that a spacecraft crashed because somebody forgot to convert. Using inches and feet is a continuing hassle.
