"Interdisciplinary Architecture" presents both historicial background on the complex relationship between art and architecture, and examples of related contemporary projects. In an introductory essay, Nicoletta Trasi gives an overview discussing the recurring issue of the integration of the arts, from Art Nouveau to De Stijl and Bauhaus, highlighting the insidious and uneven ground on which the art-architecture relationship has evolved. A concluding paragraph speculates on future developments. The essay is followed by the selected" Architectural Design" articles. Those from "Frontiers: Artists and Architects" (July/August 1997) investigate the dynamic relationship between art and architecture: those from "Pop Architecture" (July/August 1992) and "Colour in Architecture" (March/April 1996) discuss the formal definition of elements common to the vocabulary of artist and architect, such as the use of colour and the conception of sculptural forms: and those from "Tracing Architecture" (March/April 1998) examine the creative act of artists and architects.
