When I moved over my apartment, I had only a desk and a chair in my bedroom, and I ate on a tray atop a paper box. Since I love space most, it was comfortable for me, and if I did not force myself to buy furniture, I would still be eating oh the paper box. Now I have a TV cabinet, sofa, and light stand. and a small wooden table. That's all I have. My clothes and books, tools, and other all items are put into the closet. Since my closet is almost full. I won't get anymore. In a sense, I adjust my life to the capacity of closet.
Japanese houses are said to be as small as rabbit houses. (As far as I could tell, many European houses seemed to be of a similar size to ours.) So people make all kinds of effort to make space inside their houses. Then we have a various types of interspace furniture. Look at this page; this is only 15cm width (that's less than 6inches). And "How to store" (hover your cursor above each picture) is always a popular topic in house magazines and on TV show. Actually there are some "storage advisers". Hiromi Honda is one of them and here is her HP. Yeah, some of them looks like nice ideas. For example, attaching towel hungers to the backside of a shoe box, you may put slippers there. Using Cabnets with wheels inside the closet, make it easy to pick up everything, no elieminating dead space. Under the sink, tend to have a lot of dead space because of the drainpipe, but this idea looks good.
However I am not sure I want to use tape to keep small sauces like this, or hand small food bags of food on the side of my refregiatore like this.
For North American people, this is funny??. We have to creat the space because the land is so small.
