You've found some great fun!
My children, grandchildren, and I have already assembled many similar structures. The largest Lego building was 2 houses. I built them with my youngest daughter. But I remember buying 1 small Lego set for my eldest son. It was in the 90s of the last century. Legos were expensive in our country then and we didn't have much money then.
