I think that the theme choose to the unit is very interesting. I've learned very much about someone, who believes in this, can tidy up his house and can feel right when he's in it. However, some ideas from Feng Shui are odd for me, for example, don't put the bed next to the window.
Time ago, I read a book that it told a story about the First Chinese Emperor's Tomb. The title of the book is "Everything under the sky" by Matilde Asensi. In this book, it's told how the tomb was building with aid of Feng Shui beliefs. If the story is true about tomb, I only know one building that are designed according to the principles of Feng Shui.
