The brick ornamentation in Islamic architecture represents the unique skill of the architectural artists and we have seen the perfection of this kind of art during the Seljuk period. There is little information about the process of developing brick art in the architecture of Islamic mosque in Iran, and it has not yet been dealt with as it is worthy of this precious art. Therefore, it is necessary to carry out further research in this regard due to its importance in Iranian architecture. In this research, through library studies and with a descriptive-analytical approach, the trend of development of bricks ornament in the architecture of the Islamic mosques of Iran from the beginning to the end of the Ilkhan era, as well as the causes of importance and development to the bricks of the Seljuk period were studied.

Events in the building industry in Nigeria in the last decade show the important role the private sector played in housing finance. With the advent of the public-private partnership concept in almost every sector of the socio-economic spheres of the nation, the role of the private sector in housing finance cannot be over-emphasized. This paper clearly states that the low-income public servants do not easily have access to housing finance. The responsibility of generating housing finance at a relatively low interest rate repayable over a maximum period of twenty five years rests on whoever seeks for a housing loan through the Federal Mortgage Bank or the Primary Mortgage Institutions. This paper seeks mediatory role of the private sector between this class of the society and the mortgage banks to source for funds to enable them to own their houses. The research method employed in this paper is the survey research in which questionnaires were administered on members of three housing estates, two housing estates in Lagos and one in Abuja. This paper exامینes the role of the private sector in the public-private partnership in housing delivery to low-income earners in Nigeria through housing finance. The findings showed that majority of the respondents had access to either mortgage or commercial banks to source for funding or the purchase of the houses.
