The property has built two floors outside my window, blocking the lighting. Can my lawsuit succeed?

Your question is very complicated. Let's talk separately.

1. Let's talk about privacy first. If you build a house four meters away from you, you need to see if there is a window facing your window. If there is, and it has really affected your life, it may have violated your privacy.

2. In addition to the right to light, the Property Law and the Code for Planning and Design of Urban Residential Areas are generally applicable at present.

Specifically, first of all, it depends on whether the other party's building has been approved and whether it is legal, and then it depends on how much impact it will have on you, and then make further judgments.

If there are no other questions, please accept. I hope I can help you next time.
