For example, most homes (probably yours) have furniture that is not really necessary. Let's look at three of them…
TV furniture
All houses have a TV, but does it take up more space than you need? For example, why not put the TV on the wall? This way you will make the house look even bigger.
Side sofa tables
And yet they are much less useful than their cost many times over. Since you have a small table in the living room, why have it next to the sofas? If you do the lighting, it is better to have floor lamps that you can be more comfortable with in a possible move.
Living room complex
It has been a big fad in recent years and now many are rethinking this market. Unless you have a very large living room that you want to cover with furniture, this just closes your space. If you have a lot of frames and trinkets, try the idea of shelves on the wall.
