Mathematics and architecture are interrelated. A building with the appropriate mathematical elements in its design will be impressive in its appearance. One of the most widely used mathematical proportions in architecture is divine proportion, or better known as Phi ( Phi=lim(n ->infinity)F(n)/Fn-1=1.618 with F-n the n-th Fibonacci sequence). This type of proportion exists everywhere in nature, including in human body, shapes, artworks, music, paintings and even in the universe. In this study, we investigate the existence of divine proportion in modern architecture. In identifying the divine proportion, geometrical analysis was applied by measuring the dimensions of parts on the floor plan of a building in a higher learning institution in Malaysia. The length, width, height and angles of the floor plan were examined. The results show that the divine proportion, which was obtained from the proportion of length and width, exists in 33% of parts of the first and ground floors of the building examined.
