Well, a house located on a dead end street or a cul de sac is Ying heavy. Ying energies are collected at the end of the dead end street or cul de sac, and stay there. So, if you are living in a house (especially the last house) that situates in a dead end street or cul de sac, you need to allow in as much natural light as possible. Or, at least turn on the artificial lightings as often as possible. Also, try not to paint the walls a dark color, as it makes the space appears darker. Plus dark paints on the walls is not good Feng Shui anyway. All that being said, there is a plus to this. If you are a female residing in a house on a dead end street or cul de sac, it is favorable to you especially for a career woman.
