Start with the way you live.
Before choosing anything new, look at what already happens in the room. Where do you sit, gather, read or leave your keys? A useful room supports those small habits.
Give things space.
Try moving one piece instead of adding another. An open route through a room, a clear surface or a better view of a window can change how the whole space feels.
Keep the personal layer.
A considered home can still have books, photographs and objects with a story. Group the things you love deliberately and let them be part of the room.
