In the 1990s,Beatriz Colomina,in her noted article "Intimacy and Spectacle: the Interiors of Adolf Loos," discussed the sight line control and its resulting psychological implications in the interiors designed by Adolf Loos. Along with a critical review of this article, this essay offers a new analysis of Loos’s sight line design and how it resembles theater space.By examining a series of the residential space designed by Loos,I will argue that Loos developed a diverse strategy in responding to the different needs for intimacy in a home: the spatial accessibility and openness diminishes with the increasing needs for privacy.A close reading of the relevant essays by Loos included in this essay will also help illustrate his architectural position.
