When the balcony was built, it floated out one meter, but I want to float out one and a half meters,

It depends on whether the local planning department is strict with the acceptance of this link, it is not allowed in a strict place, I once did a project, the developer because of the improvement of the selling point of the house, built an extra 30cm flower pond under the balcony, the planning bureau found that there was no such flower pond on the construction information when the planning bureau accepted, all identified as illegal buildings, did not pass, required to confiscate illegal income, and finally the planning bureau commissioned an appraisal agency to issue the appraisal value of the illegal building part, and the developer paid a fine. Specifically, you still have to check the laws and regulations related to local property planning, I hope it can be helpful to you, I hope it can be adopted!

Hello, generally not allowed to change privately, if you want to change, you must obtain the consent of the original design unit, which is related to the safety and stability of the structure. There is also the consent of the property management, urban planning and other departments, and the procedure is more complicated.

This matter is not something you can increase if you want to increase it personally, it requires the consent of the construction unit and the design institute and the issuance of a change notice after calculation, and at the same time involves a series of restrictions on laws and regulations such as [increasing the construction area], [changing the floor area ratio], [modifying the planning conditions], [lighting and sunshine time], [increasing the cost of supporting facilities] and so on.
