Congratulations, how very exciting!
My partner and I are caretakers on a blueberry farm that's going on the market next week, when it sells, perhaps if there's a need for construction/plumbing/design expertise, we can figure out a way to dive in. I can't imagine living without my chickens and an intimate connection with nature anymore, even if it's my partner who does the lion's share of the physical work (I do the plannin' and the learnin' and the prettifyin' and wrangle minions harmoniously :>)
First things I'd say would be good to do is be on the land a month or so before building immovable anythings and learn the patterns of the land so when immovable things get started they get started in optimal places. (During that time would be a great time to start putting together a library)
A jillion thoughts come to mind, but low battery suggests I leave those two cents, stand back and be happy that this is happening. It's welcome news, and kudos for making it happen.

p.s. A solar bioremediation greenhouse that filtered blackwater into potable water while generating biomass for heating and biochar seems like the kind of experiment that could happen on this land of yours, yes?
