This paper describes the various steps accomplished to implement the design and construction of an additional bathroom with an existing building in Atlanta, Georgia, USA. The process of developing floor plans, getting approvals from the city, hiring contractor(s), stepwise building, and getting inspections done by the city authorities at various stages of the building process, has been outlined in detail. This sequence of steps can serve as a good case study for architectural engineering students and can provide useful materials for faculty members teaching such courses.
