Can the concrete non-bearing wall be knocked out? What should I pay attention to when tearing down the wall?

If the building is a commercial residential area in the city, I'm sorry, no matter whether the external wall is a shear wall or not, no matter how much you don't like a certain section of the external wall, the property can't allow you to tear down the external wall and destroy the facade. You should also inform the property company when you decide on the hardcover plan. Remember, if there is anything wrong with your house during the warranty period, you should ask the property management company to repair it. If you decide the plan without authorization and then change it, there will be wrangling in the future, and you will also suffer if you really take legal measures. Finally, China's construction planning department stipulates that the external walls of buildings can't be changed and demolished at will, even if the structural system is not destroyed. Once found, sabotage will be severely punished.

If you are sure it is a non-bearing wall, you can knock some into it. For safety reasons, it is generally recommended not to exceed half of the wall thickness. In fact, in addition to load-bearing walls, shear walls, shear walls and other stress walls are also immovable. Only for buildings, there are few other load-bearing walls except load-bearing walls, so only load-bearing walls are mentioned. These stressed walls are not free to move. The function of shear wall is basically the same as that of load-bearing wall, except that it has an additional function of resisting horizontal load, so it is not recommended to dismantle it. Generally, it is the wall connected between the room and the balcony, and part of the balance wall is connected with the load-bearing wall to play a load-bearing role. Under the premise of not affecting the safety, use function and appearance of the building structure, the partition wall of the non-load-bearing part of the building can be removed. So, although you bought a house, you don't want to tear down the partition. Take it down if you say so.

Some walls have hidden dangers, such as the bathroom walls, which are easy to leak after demolition and reconstruction. There is also a non-bearing wall inside the bay window sill. If it is not dismantled properly, the external wall will leak if it cracks. The walls of the frame structure are not load-bearing walls and can be removed. The frame structure is mainly loaded by beams and columns, and the wall itself only plays the role of enclosure and separation. This structure is usually used for single-family houses, townhouses, overlapping villas, etc. Generally, the external walls of high-rise residential buildings cannot be moved, nor can the partition walls with neighbors and public spaces be moved. Indoor brick walls (non-concrete parts) can be moved. It is best to get the help of professional and technical personnel.
