After World War II, Hong Kong didn't buy a house, saying that they all bought a house. Buying a house bought the whole building, so Hong Kong is still called buying a house or paying for it. Because the whole building has been sold, only wealthy businessmen, foreign firms and enterprises can buy it, so the overall transaction volume is low and the funds are slowly withdrawn. At this time, Wu Duotai, the boss of the international Hongxing Investment Group, began to sell buildings layer by layer.

Because the building area of a buyer is the same, there is no pool area at this time, because ordinary people still can't afford it. At this time, Fok Ying-tung innovated a new method of selling uncompleted residential flats, that is, splitting a floor like ours and selling it separately, which also caused our dissatisfaction with the pre-sale of commercial housing and the pool area today.

Because buildings are sold separately, people buy more, and problems follow. Because the area of each household is different, the dispute of house maintenance came out, so the pool area was invented in the 1950 s, that is, all households shared the property rights of the whole building according to the proportion of each household's land use area. That's how the pool area came from.

Area covered by pool area

The pool area contains many contents, such as public hall, corridor, elevator, lobby, stairwell, elevator machine room, pipeline well, water pump room, fire escape, guard room and so on.

Now all commercial houses have a pool area, which is shared equally by all owners. When buying a house, the price of the pool area is generally included. When handling the real estate license, the area above the certificate also includes the pool area. Including the usual real estate fees, it is also necessary to calculate the pool area.

The percentage of pool area is different for different types of houses. If the purchased house is an ordinary multi-storey commercial house without underground facilities, the pool area will be relatively small, between 10%- 15%.

If the house you buy belongs to a small high-rise elevator room, the pool area of this house will be slightly larger, which should be between 15%-20%.

If the house you buy belongs to high-rise residential buildings, the pool area is usually relatively high, generally between 20% and 25%, and some high-rise residential buildings will even reach about 30%. The pool area is too high to be cost-effective.
