ZoS, How are assets chosen to be converted into Furniture?

Mix

Every time we get new content I always wonder why did we get this asset as furniture but not that one?

So:

How are assets chosen to become furniture?

How are they converted to be usable as furniture and/or how much work is it to make a furniture item?

As a housing community we probably want EVERY in-game asset to be available as furniture. I would love to understand more about the process so when requesting new items be added I have some idea of what I am actually asking for.

How much more difficult are animated or items with special effects to add? Interactable items vs static ones?

Are structure pieces more difficult (choosing a piece of wall or a piece of floor)?

Is is possible to add more "natural" floor pieces such as grass, sand, dirt, bones etc? Specifically the pieces we see used as the "ground" around Tamriel?

@ZOS_GinaBruno @ZOS_JessicaFolsom I don't see a tag for Cullen Lee, the guy who answered housing stuff in the one ESO Live video on Elsweyr Housing, could you please pass this along?
