It is best to choose 2-6 floors for small and high-rise buildings. First, it depends on whether the distance between buildings is enough, otherwise it is easy to lack sunlight and the privacy is poor. Secondly, it depends on whether the vision of the nearby landscape is open, and the lower floors will be more affected. The advantage is that the water supply below the sixth floor does not need secondary pressurization, so there is no need to pay the monthly secondary pressurization fee and there will be no pollution caused by secondary pressurization; Besides, if the elevator breaks down, climbing the stairs will not be hopeless.
I think the best floor choice for small high-rise buildings should be the sixth floor, followed by the fourth floor, the fifth floor and the seventh floor. If it is inconvenient for the elderly to walk around at home, consider choosing a lower floor. If the building density is higher and the building spacing is closer, you can choose a higher floor, so the landscape vision and air quality will be better.
