Granting the wife a building during his lifetime

Q: I have a pious, loving and prolific wife. This is grace from Allah (Exalted be He). I married her when she was 13, and now she is 43. Allah (Exalted be He) has granted me children and Halal (lawful) sustenance. She is very obedient, Praise be to Allah for this. She never opposes me and I have no other wives. All my children, two boys and four girls, are born by her only and I have a strong desire to grant her, during my life time, a small two-floor building. This building does not exceed one third of my property at the present time. Will I be violating any part of the Shari`ah if I grant her this building? I appreciate your guidance. May Allah grant you success and reward you well, for I am very confused about this. As-salamu `alaykum warahmatullah wabarakatuh (May Allah's Peace, Mercy, and Blessings be upon you!)

A: (Part No. 16; Page No. 174) There is no prohibition in giving this building to your wife and registering it in her name during your life time. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
