A session at the Architectural Studies Colloquium explored the possible contributions to the unserved 'bottom of the pyramid' - the 'BOP'. With cities expecting to double in size in the next 20-25 years the issues are abvious and frightening. Special guest was Alyce Russo (MCP '89) of the firm Schall and Russo Planning Works, and together with SIGUS staff challenged the group to assess contributions and brainstorm possible ways to get involved.
