What do you mean by property scale?

Property usually refers to all kinds of houses and supporting facilities/equipment that have been built and put into use.

Real estate can be large or small, from a building to a flat. The same building is also divided into different properties according to ownership, which can be divided into five categories: residential property, industrial property, commercial property, government property and other uses.

It can be said that real estate is one of the most important components of a house.
