Is there a way that I can remove furniture I've built? I built two single beds thinking they were for my kids to sleep but apparently there not for them. I need to delete them.

Nope sorry once built they are there to stay, unless you revert back to an old save file before you built them.

You cannot delete furniture you have already built. Your only recourse is to revert to an earlier save from before you built the items you've decided you don't want.

If you're talking about the two single beds upstairs in the main hall, they are for your kids - if and when your kids move in. If at any point there are no children living in your house, your housecarl and steward will use those beds. If children move in later, they get the beds and the housecarl and steward don't sleep.

If you build the bedroom addition and put two single beds in there, your kids will take those beds and the upstairs main hall beds once again go to your housecarl and steward. All double beds are always reserved for you and your spouse.

Right OK thanks.

I have no kids right now but do have a Steward. I have Windstad Manor with the two single beds off the Main Hall downstairs.
