As for living together, we can say that there is nothing wrong that you live in separate apartments provided that you remain kind and dutiful to your parents.

Clarifying the Islamic view regarding living in an extended family system, Sheikh Ahmad Kutty, a senior lecturer and an Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states the following: “As far as all the grown-up children, married or unmarried, living together in the same house, it is not encouraged, because of the fact it may give rise to jealousy and suspicion when some of them are living with their wives on daily contact with men (in-laws). The Prophet (peace and blessings be upon him) said: “The in-laws are death.” This is a serious warning from the Prophet (peace and blessings be upon him, against creating circumstances for in-laws to be in privacy in the same house.
Circumstances like these may arise more frequently when all the brothers are living in the same house in the name of extended family.
Therefore, in conclusion, our duty towards our parents and brothers and sisters can be fulfilled while living in the proximity of one another in separated apartments or independent living quarters. It is well-known from the practice of the Prophet (peace and blessings be upon him) that he did not live with his extended family and wives in a single apartment. The Prophet, peace and blessings be upon him, fulfilled his duties towards all of them while visiting them frequently and maintaining his obligations towards them.”

Based on the above, it has become clear now that Islam doesn’t encourage extended family system. Above all, living in a separate house doesn’t mean severing ties of kinship with one’s family. One is asked to maintain good ties with his parents, brothers, and relatives, even without living in an extended family house.
