Vallejo Triano has also argued that the construction of the House of Ja'far took place slightly later than the other structures of the 950s because its decoration appears to be more evolved. This tentatively supports an earlier hypothesis by Félix Hernández Giménez that this large residence was built for Ja'far, a "hajib" (chamberlain) of Al-Hakam II between 961 and 971, and for whom the structure is currently named. This also makes it the only major structure in Madinat al-Zahra that has been identified as belonging to the reign of Al-Hakam II.
