How to define building's collision hitbox?

It finally works without crashing the game, but i can't enter the catwalk, the air part of it has a collision, i can walk on the air above the catwalk. And i can't figure out where i'm supposed to define the collision. Looking at default buildings didn't help, i don't see anything different there.
