Entering from the Queen Street Mall, the components of the building that served the Regent Theatre are: the single-height threshold space off the street; the large, double-height entrance hall; and beyond this the elaborate grand foyer, which retains the marble staircase that once led to the 1929 theatre's mezzanine promenade. The interiors of all these spaces are extravagantly ornamented in a confection of styles, which include Art Deco, Spanish Gothic, Baroque and Neo-classical or Empire. A key strategy employed in the design of picture palaces of this era, these styles are freely used to create eclectic visual effects without concern for historical or stylistic accuracy. These spaces form an impressive sequence, retaining coherence despite the mixture of decorative styles.
