"With cities, it is as with dreams: everything imaginable can be dreamed," Italo Calvino's Marco Polo asserts, in a remark strikingly apropos of Hong Kong. Public spaces, too, can perhaps also be regarded as a rebus that projects a city's desires and fears, although it is likely to be a rebus of a particularly complex kind. The urban density of Hong Kong produces unique physical adjacency of spaces and psychological distancing among its people. The size of many homes is reduced to such a minimum that people would make themselves comfortable in public as if at home. We peek into the homes of neighbours, share dim sum tables with strangers, and skin-to-skin with people in elevator carts that we have never spoken to. To design public space in Hong Kong, one has to go beyond the public-private opposition and explore a more nuanced relationship between the public objects, subjects, and their context. This studio concerns the manifold relations between public spaces in Hong Kong and the socio-spatial characters of the city. It pursues a particular theme: the culture-nature hybridization of the Hong Kong subject in spaces that we call “public homes”. In subtropical climates like Hong Kong, the fluctuating humidity would require an open system of lattices and shades and an architectural understanding of “air” like clouds - accumulated masses of liquid droplets, frozen crystals, and fluid particles rendered visible as a buffering medium between the inside and outside. In this studio, we develop an understanding of how people adapt to climatic and spatial conditions for the making of “public homes”- changeable, permeable, and sensual - as means to imagine and construct places for contemporary culture and shared delight.
