Same here. When we remodeled my bro said " you've GOT to have a secret passageway!". So I made one between kids bedrooms - its triangular due to roof pitch, just big enough for a kid to wiggle thru, the width of a bathroom dormer. Kids and adults are envious our house has a secret passageway. Kids are more fun than I ever imagined. Almost teens now, and its different. Still fun but challenges are more significant. Loved every stage!
