The person loves this sphere. We can say about them that they are the center and support of their family, or they strive to become one. But naturally, we differentiate between female and male charts. That is, for a woman, it is important to create her own family, to arrange her own nest, to preserve family traditions, and for a man, it is an orientation towards such close, intimate family relationships. They often strive to build their own home, where their children and then their grandchildren will gather.
The Sun in the 4th house often indicates that a person is engaged in the sphere of real estate, construction, and everything related to it.
