This design project attempts to enlarge the role of urban codes to deal with issues relevant to the condition of the metropolis as a type of ecological niche. It is my view that urban codes are the most useful design mechanism for post-environmental relations between humans and the urban fields they reside within. These codes must be written not to designate that which cannot be done, but to provoke successful innovation by those following them. This is especially the case in a metropolis without zoning such as this. The project is a master planned community in an urban instead of ex-urban context as is typical, formed on a brownfields site, which is currently the oil services company Halliburton's mostly vacant headquarters just Northeast of downtown Houston. Coding of this site to be used by developers of the site must take into account parameters inherent in the site itself, in this case a polluted parking lot lying in a floodplain. To a certain extent these conditions pervade the landscape of Houston itself, and so this is in a sense a case study for a wider field of operation.
