A complete collection of figure-eight buildings

The patio in an ancient building, in a small area, only plays the role of ventilation, and can also be used as a temporary hanging object to transport furniture vertically; Large area ventilation, little lighting.

However, a slightly higher building is a big taboo for fire fighting! Like a chimney. When a fire breaks out, it will suck in air to help fuel!

All kinds of pipeline wells, electric wells and wind wells in contemporary buildings must be divided into fire zones and sealed at the top after installation.
