Building collapses in Nigeria have gotten more shocking and heartbreaking in recent years. A compilation of fallen structures and fatalities during the previous twelve years (2016-2022) indicates a concerning trend that should be regarded as an emergency. Each collapse puts in action a series of events ranging from the loss of investment, means of livelihood, and irreplaceable human lives, as well as the void it leaves for the loved ones of the dead buried in the rubbles at different sites of catastrophe. Beyond the losses, there is the issue of what went wrong and if it might have been avoided. Are there no rules or regulations? Is it true that no institutions exist to enforce standards? Therefore, the study highlights specific locations in which members of the architectural profession are engaged in the construction industry and looks into the reasons why buildings fall. The findings prove that structural flaws, inexperienced labour, and poor material quality are the primary reasons for building collapse, demonstrating a failure in leadership and oversight. The study found that all parties involved in the construction process share responsibility for the successful completion of building projects. The architect should m ensure that his duties are carried out diligently in accordance with applicable laws while also taking all necessary steps to keep up with the trends for sustainable buildings, even in the face of formidable obstacles like extreme heat, rain, flooding, and sea level rise.
