This study investigates the effect of using steel filings from the waste of blacksmiths workshops on the clay bricks mixture to improve the bricks’ compressive strength. On the other hand, this process can reduce workshops’ waste by recycling it to preserve the resources and achieve sustainability. Adding steel filings to the mixture of red clay bricks was in different proportions by weight (1%, 2%, 3%, and 4%) on prototype bricks produced in a lab. Moreover, it aims to increase the effectiveness of clay bricks used in load-bearing walls, which can be used extensively in economical housing to reduce the cost if its strength increases by utilizing it in the load-bearing walls system instead of skeleton. The experimental approach was adopted to reach conclusions, as it is the appropriate approach suitable for this research. Before and after adding steel filings, many properties were tested, such as dimensions, weight, density, water absorption, and compressive strength. It is observed that on increasing the steel filings ratios by the mixture’s weight, the prototypes’ compressive strength also increases. The highest percentage of increased compressive strength occurred for the specimen with 3% steel filings by the mixture’s weight is (84%).

Architectural education revolves around a fundamental axis, which is the architecture design studio. The learning environment in general affects student’s creativity. Few studies dealt with the most crucial space in architecture design course, which is the architecture design studio classroom. The application of this research is to determine the student’s satisfaction degree about the architecture studio design in the department of architecture in NUB and the main variables affect the quality of the internal environment of design. The researchers used the descriptive and analytical approach in research implementation. Research results are associated with the Architectural Design Studio only. The research community consisted of )42( students who study the Architectural Design course in Nahda University. The analysis result showed the effect of the design studio's design on the students' psyche and their level of performance. Through the study the necessity of focusing on the distribution of internal furniture in the design studio and taking into account technological developments in the work by not relying only on drawing tables, but taking into account the provision of a special zone for using the computer as it became a basic tool in the architectural design process.
