"Room Book" says: "Three rooms are auspicious, four rooms are few, and five rooms are empty". In the house of Yang, the odd number is considered as Yang, and if it is even, it is mostly used in the house of Yin. Three means a lot of things, that is, the number of bills paid when buying a house, and the singular number represents auspiciousness, not only the floor, but also the room. The same is true of the number of stairs.
Many bosses are sensitive to odd numbers, especially when buying a house. They believe in feng shui. They think that a single-story house is special, and Feng Shui points out that odd numbers are auspicious, but for the rich, the house must be auspicious, so as to bless the smooth career and protect the health. Although this statement is unscientific, it is undoubtedly a very practical psychological comfort for the rich.
Should the stairs be single stairs or double stairs?
In fact, the number and height of stairs need scientific design. Height and order are very particular, not nonsense. Some people don't understand that it is dangerous to get a tall and long staircase. In fact, it is not only the family, but also the office environment and public environment. There are many places that need stairs. I have seen reasonable designs and very unreasonable ones, even in some big cities.
Adjust according to the crowd: A good architect can adjust the design according to the target crowd. If it is an apartment for young people, the order of stairs can be 1 1, and the height of each step can be 16cm. If it is an apartment for the elderly, the number of steps should not exceed 9 at most, and the height of each step should be reduced. Actually, it makes sense.
The stride of the old man and the height of lifting his feet are limited, so it will be comfortable and effortless for the old man to walk on such stairs. If you give it to young people, they will have a desire to take two steps at a time.
In short, even or odd stairs can't be messy. Need specialized personnel to carry out scientific and reasonable design according to the user's situation. Only by comprehensively considering multiple factors such as feng shui and height can we design stairs that meet the needs. Don't be superstitious about odd or even numbers, it's normal to match single and double.
