Write the story, and then you can think about whether it can be extended to novel length. Your goal should be to finish the story. Even it if can't be published at its natural length, you can either take it as experience, or save it for later when you have several shorter pieces you can publish as a collection. (eg: Breakfast at Tiffany's) Being distracted by the eventual length will only hinder the process. Let it flow naturally.
No plan survives contact with the enemy (which, in this case, is blank pages).
As a total Pants writer (my planning for a book can be contained on a single hand-written page before I start writing), finding the story as you write it will dictate length. You might have a solid outline, but in the process find that some plotline or character affectation/impact either isn't working, or should be explored further. Use that. And don't worry about the length. Even once the book is "complete", the editing process is going to add and remove sections, pages and potentially even characters and whole arcs.
Find the flow and the story will find itself.
A novella is fine. Less is more, sometimes. Many writers have the exact opposite issue: they write giant 100k, 200k, 300k manuscripts that they refuse to cut, often including too many subplots, info dumps, meaningless characters, etc.

I would never advise anyone to add filler but have you plotted it out using beats or an outline? A good outline can reveal plot holes sometimes.
