Globally, Development Control Departments play a crucial role in overseeing effective physical development in urban areas. Architects, as key figures within these administrative units, hold a pivotal role in shaping the vision that materialises into the built environment. Their active involvement throughout the developmental process is imperative. This research is centered on optimising urban development and specifically provides an overview of the 'Role of Architects in the Decision-Making Processes of Development Control Departments in Greater Port Harcourt City’. The objectives of the study are to determine whether the current representation of architects aligns appropriately with the scope and responsibilities of the Development Control Department of the Greater Port Harcourt City Development Authority, outline the specific roles and responsibilities of architects within the department, and assess the extent to which architects' inputs are considered in the decision-making process for granting building permits. Additionally, the research aims to propose recommendations for optimising the integration and influence of architects in decision-making processes, ultimately contributing to sustainable and aesthetically pleasing urban development in Greater Port Harcourt City. Data collection for this study relied on a semi-structured interview guide, which aligns with a qualitative research approach. The results indicate that only two architects were employed, with one remaining. While architects’ inputs were considered at the commencement stage of the authority, it was revealed that the current practice in the Development Control Department no longer involves physical vetting by architects. Instead, reliance is placed on a check-list that only requires the ARCON stamp and architects' paper certification. This approach has rendered the architect physically present in the department redundant. In conclusion, this study emphasises the critical role of architects in shaping urban development and underscores the necessity for an adequate number of architects actively participating in decision-making processes within Development Control Departments. It strongly advocates for the reconsideration of physical vetting processes, affirming that such practices contribute to better urban development outcomes and align with the overarching goal of creating sustainable and aesthetically pleasing urban environments in Greater Port Harcourt City.
