My advice would be to generate a visibility graph between all the
concave points (corners) in the interior space. You can then use this
along with a dijsktra's shortest path algorithm or similar to generate
paths between these points. From there it's fairly straightforward to
generate paths from anywhere using isovists to see what vertices are
visible.
