Staircases are often part of the entrance to your place or at least to your building. When buying or renting a space, feel what the entrance says to you. Is there light, is it dowdy, clean and has fresh air. Ideally, it should not be placed at the front door or in the middle of the house. If right at the front door, the energy rushes up and back down constantly. Feng Shui says to avoid it but this is often a characteristic in European homes. Place small items or lamps on the stairs which ensures people take their time using the staircase, place interesting art work or a colour appropriate for the door placement in the bagua map. Yet again, to slow people from shooting up and down. Feng Shui prefers wood elements rather than metal however, stone can ground the energy.
