Nope, what you see is about 90% work by hand/shovel. the only machine we used was a rideable mini dumptruck (1/2 m3) to transport dirt to this giant. Dumped it and put in place by hand. Took us about 3 weeks.
The most dirt is from the forest itself, but we can call the council for extra dirt when we need it. Just to protect the forest for dirt shortage :p For this double we got 60m3 fresh HD Dirt from the council. The landing itself is about 100 m3 of dirt
