I would recommend looking at your spaces with fresh eyes, as if the rooms were empty, and think how you would like to use your space and what you enjoy....and if you can, I would recommend doing this across multiple rooms together... as something that once served a purpose - might no longer be the case. Then look at what you do have, and how it might be useful in a new way....maybe now is the time to move that large sofa to create a snug room or put that armchair in the window for a relaxing solo reading space. Remember, you can always change it back, so feel free to go wild!
