Using common building materials Elspeth Pratt constructed a unified design over nine windows. In general Pratt uses forms and materials that align more closely with architecture than the history of visual art. At times she directly references the space she exhibits in, but more often her abstract sculptures carry direct references to other, more ubiquitous architectural spaces. For Bluff, Pratt responds directly to the space, but also makes reference to more general and proverbial architectural forms.
