(1) Dear Uncle Dixer: Are stairs at the Southeast good for first floor in Feng Shui?
Answer: Southeast is associated with the Xun Trigram and the Phase Wood. It is also the direction of the Earth Gate. So when wind blows through the Earth Gate it will send things upward and can be considered auspicious.
(2) Dear Uncle Dixer: My stairs are located in the Southeast area. Is it good for a two-story residential house?
Answer: The Southeast is correlated to the Xun Trigram and Xun is associated with wind. Since wind moves and is active, Southeast is an appropriate direction to have a stair case from this perspective.
