The Red-Line Park project (RLP) is conceived as a critique to the current Chinese urban condition that we call Urban Suburbia. The city fabric is severely fragmented by large developments in the fashion of gated communities. While sizes of average apartments increase rapidly, shared public spaces are squeezed to minimum. Red-Line is the literal translation of property line in the context of land usage, on which stand gated communities' boundary walls, the signifier of the divide between the private and the public. By way of grassroots initiatives, current walls can be replaced by RLP Units, and eventually transformed into a system of linear public parks. While occupying zero square feet in urban scale, RLP provides spaces for landscaping, resting, playing, exercising, socializing, gathering and even gardening. Eventually, RLP will see the demise of the walls and make it possible for reconnecting the once segregated city into a synthetic whole.
