There is a yard on the first floor of the house.

It shouldn't affect you, but if you build houses in both yards, it will affect your sunshine if you build them too high. If your yard is so green, it will look dark. Darkness will affect your mood. If you are in a bad mood, letting us do anything may have a negative impact.

Besides, other people's houses have been built and you haven't, so it doesn't look very harmonious and beautiful. In fact, you should report them, or you will have to build a house in your own yard, so that there will be more houses and it will look more harmonious.

So it is up to you to decide and plan.

Building a house in the yard is obviously illegal.

We can negotiate for them to tear down the house.
