The newly bought building has many defects and problems, such as the ringing of the main wall and the exposure of the steel bars in the balcony side windows.

It is impossible to win a lawsuit just by looking at photos.

Building quality problems can generally be divided into two categories. One is construction safety. When this evidence is conclusive, compensation can generally be obtained. The other is the problem of quality deviation, which is usually handled by repairing.

Your photo shows that the wall seems to be a filler wall, and there is no big problem. The knocking sound is probably due to the weak bonding between plaster and wall surface, which leads to the empty drum of plaster. This is a common building disease. It is a routine treatment to shovel gypsum and repaint it. It won't be hollowed out after it is processed. Even if the problem is solved.

The reinforcement on the windowsill is not like stress reinforcement. It is estimated to be used for construction measures such as Rachel reinforcement, temporary fixation and hoisting, which can be cut off or buried in buildings. As for the inclination of the window, it can be adjusted. The uneven top of the shed can be plastered and leveled. The foam glue between the window frame and the wall can be leveled or taken out from the shallow groove for plastering. In short, although the quality of building construction is really flattering, there is no building safety problem from the photos.

There are only two ways to win the lawsuit. One is to find someone who understands it and check it again, and find that there is something wrong with the safety of the building structure; Second, from the spiritual level or other levels, such as delayed occupancy, overpayment of rent or human feelings caused by delayed occupancy, and inadequate repairs. You may get some compensation. However, it is also necessary to have conclusive evidence and wise people to participate in the consultation.
