What do you mean by super high altitude?

A common term used by real estate developers to promote real estate is generally used to describe that the first floor and the second floor of the building in the middle of the building are hollowed out (that is, connected) in the living room and the height is relatively high. It is also used to describe that many commercial houses with a height of more than 3 meters are empty, also known as vertical pulling, which is a term in the real estate industry in China. In the living room and other parts of villa or duplex indoor space, the second floor often retreats, which makes the local floor reach more than two floors. This part of the space is called empty.

The height of the vacant floor is usually more than 5 meters. When selling, only one floor is used to calculate the construction area; In practical application, empty space can highlight the sense of space and comfort of villas or duplex houses.

empty-picking is not only applied to residential products such as villas or duplex, but also more common in hotels and office lobbies.
