Over the past few months (in 2024), I built a greenhouse with a bit of help from the Lane boys... The total cost of materials so far has been about NZ$700... It's taken 6-7 weekends so far. Next steps involve building the internal structures - some raised garden beds, and a bench with shelves for seedling/propagation trays, and other prep work (it'll have water jugs ('jerry cans') below it as thermal mass)...
