How can a Nav Mesh connect through doorways?

I have a “box” object scaled to be a large plateau. On this box I have placed some “house” objects that have no floor. The resulting navmesh does not connect the interior of the “house” to the exterior. How can I get the nav mesh to work through these “doorways”?

Problem was that these were imported .fbx without including custom physics colliders. This means that the collider was the bounding box and there was no opening on it.
