If the balcony is closed after the balcony is exposed, must there be tiles under the window?

Judging from the picture, your house is a shear wall structure, and under normal circumstances, the balcony platform mouth beam bears the load of the balcony slab and transmits it to the cantilever beam or frame beam, which cannot be removed.

Unreasonable, please ask whether the charging department is the property management company or the construction team of the closed balcony.

Balcony wall tiling is only a method of wall finishing decoration, not necessary, its advantage is that it is easy to clean, not afraid of water and moisture. In addition to this, it can also be treated with a painted finish.

There is no such provision.

The main advantages are good sealing, good warmth, and can effectively prevent rain, dust and sand. When filling the balcony floor, it must not be directly filled with cement mortar or bricks, which will increase the load of the balcony and cause danger. >>>More
