1, illumination range. Because the north and south of the apartment are transparent, because it is in the east, and because the overall layout of the apartment is not obviously recessed into the building plane, the lighting on the fourth floor can meet the user's requirements for light. But it is true that the farther you go to the upper floor, the better the lighting will be.
2. elevator situation. The fourth floor is suitable for climbing stairs and elevators. Take the elevator when you are lazy, and climb the stairs when you are diligent. When there is something wrong with the elevator, the advantage of the floor is particularly obvious.
3. Floor water pressure. The water supply upstairs is a problem. Generally, the water pressure in the lower floors is ok, and there is a water tank on the top floor. It is very troublesome for buildings above 10. In many residential areas, water supply is generally stopped at the 10- 19 floor, and rarely stops at the upper and lower ends.
4. Are there any elderly people living at home? There is no doubt that some elderly people choose shorter floors. When I bought a house, I asked my mother for advice. She doesn't like living too high, so I didn't consider floors above the sixth floor.
5. Price: per floor, the price per square meter will be higher accordingly. 20 yuan/building/square meter in our community. How many floors later, the tap water pressurization fee increases the cost of buying a house, depending on whether the individual needs it.
The above is my experience, and I hope it will be helpful to the subject, although it was a long time ago.
