Dreams only happen when we pursue them, and it looks like you are already on that path! What you describe, with the bigger scope of the eco village, sounds perfectly wonderful and definitely adequate.

If you start off with your 50 sq meters, are you able to add on at a future time without requiring a permit, or is it based on the total structure size even if it was unplanned at the time?

Please do keep us posted on the progress of this project, it is too wonderful to miss!
