Changing the chipped white hollow core (boring) interior doors to 6-panel unfinished red oak solid core slab doors.
Nine of them. With clear varnish painted or sprayed and gold knobs, three of them locking. Going to take some professional carpentry to finish this project.
UPDATE: Let there be light! An electrician retrofitted three hallway can lights with white LEDs and for the first time it looks bright in the passage to the living room. Doors probably be installed next week.
