Interior and exterior demolition: Which walls cannot be altered or removed.

Load-bearing walls: Load-bearing walls are the walls that support the entire floor's weight in a building and cannot be removed or replaced. Removing or replacing them would compromise the structure of the entire floor, posing significant safety risks for future residents. Even opening windows in load-bearing walls is not feasible, as it would weaken the wall's load-bearing strength.

Deadweight Wall: A deadweight wall refers to the wall between a room and a balcony. This type of wall is commonly found in bedrooms, living rooms, and family rooms. The doors and windows of the deadweight wall can be removed and replaced, but please note that the wall below the window cannot be removed or replaced. The wall below the window is an important part, acting like a lever, supporting the balcony. Inner MongoliaIndoor and OutdoorDemolition and replacement of this section will leave the balcony unsupported, causing it to sag and, over time, potentially detach.

Reinforcement Bars in the Wall: The reinforcement bars in the wall are the supports for the entire house. If damaged, the load-bearing capacity of the wall will be affected. In the event of an earthquake, it can easily lead to collapse. Moreover, during home renovations, it is not advisable to drill holes or install windows in reinforced walls, as this is not only difficult to install but also affects the wall's load-bearing capacity.
