Kolatan / Mac Donald Studio(New York City, New York, Established 1988)
Sulan Kolatan and Bill MacDonald met at Columbia University in New York City, where they both earned graduate degrees in architecture. They founded their interdisciplinary design practice, Kolatan/MacDonald Studio (now Kol/Mac), in 1988, and have taught at Columbia's Graduate School of Architecture, Planning, and Preservation since 1990.
Much of their design process stems from a flexible computer-assisted method called "co-citation mapping," in which the visual and spatial characteristics of a given image or object are converted into numerical data. The resulting values are input into computer modeling programs and used to generate form, effectively creating a conceptual relationship between the new object and its source.
More recently, Kol/Mac has experimented with monocoques, three-dimensional forms in which surface and structure are fully integrated. A project titled Resi-Rise, for instance, combines aesthetic and structural considerations into a single system which, in turn, results in a skyscraper's exterior shell.
