What if the neighbor hits the wall?

First of all, as long as the load-bearing wall is not demolished or demolished on a large scale, it will have little impact on the balance of the whole building, but there is still a small chance that something will go wrong.

Secondly, we should know whether the garden next to it is public or private. If it is private, it is not illegal.

Finally, in terms of property, from the perspective of property management and the provisions of the purchase contract, any household needs the consent of the property to transform the house. If it is dismantled without authorization, it will be responsible.

I can't give you an accurate answer because I don't know if your neighbor has permission.

I hope the answer will help you.
