I have a few questions I can't find answers to online:

1.) Everything I can build BEFORE making the small house into an entry way: animal pen, apiary, armorer workbench, garden, grindstone smelter and stable.

These will not disappear, or be altered when I create the main hall and adding on wings correct? Will I have the option to remove them? Will it ever be necessary to remove these above listed?

2.) Am I stuck with the same steward permanently?

I have faendal as a follower currently, but I don't want to make him a steward if this removes him as my follower and/or if I cannot switch to a different steward later with no consequences.

There are allot of different choices for stewards and I want to know if I can switch stewards later.

Last of all, I have only built the small house so far. I see an option to remove the workbench inside. Why would I ever remove that workbench?

I hope this isn't too complicated to answer.

So if I make my follower a steward, I lose them as a battle companion and main follower? They become steward and stay at the house? I don't get it.

So with all like 30 choices of different NPC's available to be hired as stewards, I am stuck with the same one forever?

So I have to kill faendal to get a different steward if I don't like my choice later? I am confused. I need more than onesentence answers please.-

And what about marrying your steward/follower?

Bump

You can marry your steward or Housecarl.

Yes, you can still take your steward into battle. I did it quite often with Annekke...

If you make your current companion your steward, he will remain your steward until the time of his death (either at your hands or at the hands of the random bandits, dragons, giants and so forth that occasionally attack your steading). There is no way to remove him/her from your services, at least at this moment I don't remember there being a dialog option saying "Your service are no longer required....so beat it." You might want to make a special save file to test this out. Save, make him your steward, look for dialog (should be at the bottom), reload. But again, to my current knowledge, your Steward is permanent until their death.

You are stuck with that same steward forever, but only at that Steading. So you can have a steward at Lakeview Manor, a different one at Heljarchen Hall, and a third different steward at Windstad Manor.

Yes, you'll have to kill Faendal to get a different Steward later if you want to change him (so far as I can recall). Your best option is to create a save point before making him your Steward. Thus you can see if he fits as your Steward, and if you don't like it all you need to do is reload and it never happened. Now! I do know that there are some followers that will keep their "Follow Me" dialog option after becoming your Steward, but others do not. So once again, test this.

You can indeed marry your follower, and I would assume you can marry your Steward as well...but I haven't tested this myself. Personally, I prefer having lots of people in my home, so each role is a different person.

I woud be confused too if I was running the same thread on two different forums. You didn't give us much time to answer you but my reply was the same as those here. Que sera sera
