What does "building structure: concrete" mean? Is it a frame? Or a brick? Can the wall inside be torn down?

"Reinforced concrete" means reinforced concrete.

1, whether the wall can be knocked is not directly related to the thickness of the wall. Some infilled walls are thick but not load-bearing, and some walls are concrete walls, which are thin but load-bearing.

2. The partition wall between the balcony and the room is an outer wall, and tiles may be stuck outside, but if it is a frame structure, this wall can also be removed. Therefore, it is uncertain whether the external wall can be demolished.

Although you provided the architectural drawing, it can be preliminarily determined that it is a frame structure. The reason is: generally speaking, if the wall is load-bearing, the concrete column should be a structural column, which is generally the same thickness as the wall and will not protrude from the wall.

In addition, there is a simple method. You should see the materials used to tear down the walls of other houses. If it is a load-bearing wall, it should be a machine-made red brick or cement brick, which has a certain strength. Other materials used for non-bearing walls are usually porous or loose lightweight materials.

In addition, there is a simple method. Generally, if it is a load-bearing wall house, it is usually below seven floors. If the house exceeds this height, it can be preliminarily determined that it is a frame-bearing house.

Really can't. You can send the structural drawing of the house to have a look.

I hope it helps you!
