layer 1
Pros:
Convenient transportation: direct access without waiting for the elevator.
Suitable for seniors and children: reduce the use of stairs or elevators.
Easy to decorate: easy to handle materials.
Cons:
Low security: susceptible to external intrusions.
Noise interference: When adjacent to a street or public area, it is noisy.
Relatively poor daylighting and ventilation: The building structure can block out natural light.
Prone to moisture and insect infestation: The first floor is prone to moisture, introducing pests.
Second floor
Pros:
Convenient transportation: the waiting time for the elevator is short, and it can be quickly evacuated in case of emergency.
Increased security compared to the first floor: windows are less susceptible to outsiders.
Cons:
Noise issues: Although superior to the first floor, it can still be affected by noise from downstairs or from the street.
Lighting and ventilation: slightly improved, but still limited by the distance between buildings.
Three floors
Pros:
Increased security: Relatively difficult to access directly from the outside.
Low noise: far from the ground, the noise impact is reduced.
Improved daylighting and ventilation: Better daylighting and ventilation may be achieved as the floors are raised.
Cons:
Accessibility begins to decrease: regular use of elevators or stairs is required.
Evacuation issues: Evacuation is relatively complicated in the event of an emergency such as a fire.
Middle floor
Pros:
Balanced lighting and ventilation: generally unobstructed and in good natural conditions.
Relatively good security: neither too low to be easy to intrude, but also very high enough to make evacuation difficult.
Less noise impact: Stay away from the noise of equipment on the ground and top floors, and enjoy a relatively quiet living environment.
Cons:
Moderate accessibility: Elevators or stairs are required, but not too cumbersome.
Evacuation problem: more complex than the bottom layer, but not the most serious.
Top floor
Pros:
Excellent field of view: Usually unobstructed and has a wide field of view.
Optimal lighting and ventilation: Located at the top of the building, the lighting and ventilation conditions are optimal.
Good independence: there is no floor on the upper floor, which reduces the noise disturbance caused by the residents on the upper floor.
Cons:
Temperature issues: It can be too hot in the summer and too cold in the winter because the top layer is in direct contact with the outside air temperature.
Risk of water leakage: The top floor is more likely to experience roof water seepage.
Inaccessibility: Located at the highest point of the building, completely dependent on elevators or long stairs.
High maintenance costs: Roofing equipment or waterproofing may require additional maintenance.
In summary, each floor of a small high-rise has its own unique advantages and disadvantages, and the choice of living needs to be weighed against individual needs and preferences.
