Buildings and other static objects like doodads (gates, archers, etc.) have something called "pathing maps" which are specific files that determine how units collide with them.

A good example of a pathing map is the arch doodad. You can walk under it, but not into either of the pillars. That is a pathing map. It's more complex.

Normal units are the ones that simply use a circle of area. If you want to fix this, I believe you'll have to change your building to a unit, or find a much larger pathing map.

Pathing Maps are small TGA files made up of basic colors.

A full explenation of Custom Pathing Maps by world-editor-tutorials can be found here.

You may use ''Pathing blockers'' around your building, but if you're having alot of large buildings like you're talking about, then the game might lag a bit due to the use of many ''Pathing blocker''

Pathing blockers are feasible for already-placed buildings, but might be tricky to trigger properly placing them if the building is constructed in-game. Ty for the link, Rui.
