I repainted all the bedrooms, we have 4, ours was the last, it is simple with nice clean lines, I am lucky as I have a U shaped walk in robe and an ensuite. We did come from a much smaller 3 bedroom house so I know how it's important to have a place for everything and everything in it's place. But if in a hurry to tidy I throw everything in the robe, so it does have a downside being large, it fits lots of stuff LOL. I suppose I could get rid of some shoes ..... nah !!
If you have kids you expect clutter, you can't help it.
The easiest way to attempt to keep a room tidy is to attempt to put things away as you've used them, I can try.
