If I had 20ft tipi (I've had 2) I'd physically occupy that land space right now. A tipi stands up straight and tall with presence.
I'd take my scythe and cut a circular area and start preparing poles. I feel that I occupy it with my intent and vision.
The first experiential workshops would be:
Painting the bare canvas of 20 ft tipi's in Australian flora & fauna theme, preparing poles and setting them up.
Scything - a line of us cutting the field - it's about 6 acres.
Building composting toilets in various natural building techniques, especially with reciprocal framed roof's which harvest pure water.
Update/edit November 19. I have expanded on 'Beginning experiential workshops on 6 acre venue space' at 'One Hectare' in Self sufficiency; viewtopic.php?f=12&t=6314&p=19237#p19237
