My Parents are wanting to update it but were unsure of which style to go with. I found a house that looks like it was built around the same time and has similar bones as the Tekulve home, including the same stair-rail. These are some before and after pictures of a stair-rail from The Hillside Home that was beautifully updated.
As you can see, it is very similar to my mom's rail. Even the same type of stairway set up.
Both houses aren't craftsman style homes, but the clean lines still compliment the architecture of both homes. This would be a nice update to my mom's home and will help bring up the value if they were to move.
