This ONGOING research aims to present the evolution and transformation of city infrastructures through a synthesis of typological architectural elements. Walls, columns, stairs, openings [windows, doors, skylights], have been used in a continuous game of re-invention in the urban dialogue since 3000 BC. From the use of art and beginnings of writing on clay ‘walls’ of Nineveh (700 BC), the stone ‘doors’ of Stonehenge (2400 BC) to an array of contemporary architectural examples, a set of categorical element typologies are examined within a sequence of themed element cities. An exploration of these elements is  analyzed through a range of prototypical case study transformations and their ability to communicate historical, figural, political, experimental, artistic and structural ‘element’ architectures within the city.
