As metropolis that only emerged during the last century, Hong Kong is arguably both product and beneficiary of globalization and free market philosophy. Furthermore, it bears the contemporarily most expensive and speculative property market and is one of the most densely populated regions, worldwide. This given reality of condensed challenges provides a particularly tempting laboratory for architecture. The objective of this master‘s thesis is to examine and debate the relevance and potential of architecture in the very complex context of Hong Kong. Based on a local architectural vocabulary, its aim is to continue a dialogue within the built structure of the city; between the city’s past, its present and its future. Accordingly, the work begins with a descriptive outline of Hong Kong that reveals and debates qualities and identities of the supposedly generic city, followed by a strategic analysis of four selected reference projects – exemplary relicts of Hong Kong architecture – that results in a collection revealing the city’s complex architectural substance. The definition of a specific typological as well as topological potential, finally, prepares and preludes the design work. As almost identical twin, the design is an abstracted, mirrored duplication of an existing vertical factory; a model, specifically adapted for locus and zeitgeist that displays and re-interprets the typology in a formal, as well as in a programmatic sense. Ultimately, Twin Factory is a transformation without rhetoric, a synthesis that interprets available architectural substance as cultural artefact; it is a memory lesson in architecture.
