In this project, the question is posed of how the structure of a villa can perform as a programmed space or in contrast, how the program performs as a structure. This villa consists of two elements; first, the structural grid which is the result of transforming a beam and column system to a spatial Cartesian network of cores, and second, a glass box that is sited on the grid. The grid performs both as a private space and an active structure for the glass box which holds the public programs.
