No, not the Universe, only the space and surfaces that are lost in your home. Well, no lost, only unused. When you move into a home, you have to find the place for everything. And no matter how much larger your home is than the last one, there never seems to be enough room for everything. This is because of the empty size of the rooms, people tend to put stuff rather aired through the house, an leave a lot of unused space behind. At first sight, you don’t see it because it either a small crack between a piece of furniture and the wall, or just a large space, hidden behind a small plant.
I often notice the space from under the staircases and almost always ask or study what it’s used for. Remember Harry Potter? He used to have a whole room under the stairs. Now, I don’t say you should punish your children that way, but this only shows that this is a rather large space that can be used for various things. In most of the cases I saw, the space underneath the staircase is unused, just paneled with carving and something put in front of it to fill the empty space IN FRONT of the staircase. Second place goes to closets, sport, coat or only shoes, it is a very used space for storage. The problem with this is that it’s outdated and a very used idea. Under smaller staircases I saw washing machines, doghouses, or in one case, a toilet (concealed, of course).
This one thing I found in a picture looks something new, original and interesting, household appliances: fridge, washing machine, dishwasher, dryer or whatever you can think of. Just make sure they are front-loaded and fit in regarding both size AND color/style etc. Why waste space in the kitchen, especially if it’s the dining room as well. If it is close to the kitchen it’s even better to shorten the trip.
