Measuring the significance of façade transparency in Australian regionalist architecture: a computational analysis of 10 designs by Glenn Murcutt

Historians and critics argue that a key characteristic of late twentieth century Australian regionalist architecture is the close visual connection it creates between the interior and the landscape. While various design properties are allegedly responsible for this connection, one of the most tangible of these is associated with the use of transparent and layered elements in a building's façade. Indeed, as exemplified in the work of Glenn Murcutt, the importance of façade transparency is a recurring theme in Australian architecture. But is it really that significant? In this paper, computational fractal analysis is used to measure the difference between the visual complexity of opaque and transparent depictions of façades. By comparing these two façade conditions, first in sets of elevations derived from 10 of Murcutt's houses and then in a detailed review of one of Murcutt's most iconic works, the Marie-Short House, this paper calculates the visual impact of transparency on the characteristic complexity of Murcutt's architecture.
