summary: generally not.
stairwells can't be counted as missing corners. Generally speaking, the missing corners of stairwells don't exist, because it is with stairwells that our houses can form a complete and square pattern, and they belong to people's application and activity space and are actually used. Therefore, stairwells can't be counted as missing corners of houses.
The meaning of missing corners in a house:
1. Missing corners in a house is not a house with a square pattern and an irregular shape. The lack of corner of a building refers to the shortage of one side of the building, or within two-thirds of the shortage. The house is in a concave or inclined state, showing an irregular square or fuzzy inclined polygon, with the center of gravity shifting, being light and biased, or leaning left and right, or being large in front and small in back.
2. The quadrangle in China ancient culture is designed with its square house, which is the safest and most blessed home. Where does the word house corner come from? Simply put, this is based on the ancient theory that the sky is round and the place is round. However, in many modern houses, it is not reflected at all, so the word "lack of corner" appears.
3. The center of the building is the center of the building, and the farthest point connecting the building is a circle with a radius (including the inner balcony, but excluding the outer balcony and bay window). If the length of the missing part is equal to or greater than 1/2 of the whole radius, it can be regarded as a missing corner, and if it is more than 2/3, it can be regarded as a serious missing corner. If it is within 2/3, what is missing is not the main orientation. For example, if the house has less southeast corner, it is the position of the eldest daughter. If there is no daughter at home, it doesn't matter much.
