Once upon a time I went to an Asian country which had the most compact hotel room I had ever scene. At that time it was the most expensive price I had paid for the room. But I was told that that this was a tightly packed country and with very high real estate prices hence the prices were high. This was an explanation I had to accept. I was wondering how good an interior designer you should be to pack all that into such small space and then place the mirrors strategically so that it gives an illusion of space.
Once I was talking to an Architect he explained to me how creating spaces in architecture can make a huge difference in the environment it creates. It was something that I saw being practiced here.
