The load-bearing structure under this kind of balcony is not enough and the load-bearing capacity is very poor. Heavy objects cannot be placed on the balcony, nor can they be modified at will.
First, carrying capacity. Maybe you've heard others say that balconies could be transformed. The kind of balcony you heard about is a concave balcony. The structure of the recessed balcony is exactly the same as that of the house. There are enough load-bearing columns underneath to support them. The carrying capacity can be said to be very good. They can be converted into other uses. There is no harm in placing random heavy objects on it. The difference between convex balconies and concave balconies lies in the issue of bearing capacity. Usually other balconies must be paid for in full, so many people will buy rooms with raised balconies at a low price. These two different structures of balconies have different practicalities. If you plan to transform the convex balcony into other uses and use it as indoor space, the developer will definitely make excuses for various reasons, but will not mention the actual reason that "the bearing capacity cannot be guaranteed". For the transformation of other balconies, the application Basically it will be approved.
Second, appearance structure. The bay balcony is completely exposed to the air and has no supports. The recessed balcony is equivalent to being wrapped in a wall, making the space for renovation larger and more practical. On the contrary, the bearing capacity and deformation capacity of the convex balcony are poor.
Third, practicality. Projection balconies are usually half price, while concave balconies are full price, this is the price difference. However, the difference in price can have a big real impact. The protruding balcony can only hold some potted plants and dry clothes at most. Alcove balconies are functional rooms that can be turned into leisure areas, gyms, temporary bedrooms, etc.
If you have the idea of ????renovating your house, you must keep your eyes open. One cannot choose a protruding balcony, and the other cannot choose a balcony wall close to a load-bearing wall.
