Also, I like the idea of using wood, it is sustainable and can be re-used when priorities changes.
On building a house, either you make final blueprint or make it modular.
When my house was built in my hometown, I was away 98% of the time. When I came home it looked so different, I was angry. Maybe the next time, I should be 100% present.
Good luck on your future plans and future house!
