Recessed Retaining Wall + timber shed with corrugated iron

I am looking at putting a recess retaining wall into an existing retaining wall and then put a timber shed around 3.5m wide by 0.9m deep. The shed will have an open section (roughly 2m wide) and then two closed sections with door. I have attached photos of the exisiting retaining wall and an a picture of an open shed (not timber) the roof will need to angle away from fence. Dirt to be disposed of and suitable floor for shed also required. Thank you
