The archaeological potential of the site is unknown. The Torin building is a highly intact example of a small scale industrial building designed by Marcel Breuer in the Late Twentieth Century International style. The architectural elements and sculptural aspects of the external facade are still in place and the internal and external fittings remain in situ. It is a rare and relatively intact example of a Late Twentieth-Century International style industrial building in Sydney. As at 7 July 2009, the former Torin building is of State heritage significance as a rare and intact example of a Late Twentieth Century Modernist style industrial building designed by internationally acclaimed master architect Marcel Breuer. It is the only Marcel Breuer building in NSW and Australia and is one of a suite of buildings specifically designed for the Torin Corporation located throughout Europe, Canada and the United States. The Torin building in Penrith was the last of 9 buildings designed for the Torin Corporation by Marcel Breuer and the form and design inclusions of this building had evolved from the visual and technical experience of the Torin Corporation buildings preceding it. The Torin building in Coombes Drive Penrith differs from the early Torin Corporation buildings which were more classically gridded modernist work. The Australian example is a strong expression of the powerful sculptural mode of Breuer's later career. Marcel Breuer gained a stellar international reputation early in his career while studying and teaching at the Bauhaus in Dessau in the 1920s. It was here that he designed the famous Wassily chair among other achievements. He later joined the also famous Walter Gropius in partnership and continued to develop his architecture which by the later years "illustrat[ed] the cubist sensibility of this sculptor architect " and gained him the reputation as "one of the most important form givers of our time". The Torin building in Penrith is a fine example of Breuer's Torin Corporation architecture and the principles of his modernist design work where form is primarily determined by function. Like other of the Torin Corporation's small scale industrial buildings, the Torin building in Penrith is a good example of the way in which Breuer's design raised his buildings to a new modernist aesthetic level which ensured there was economy in plan form, bold architonic expression and the repetition of industrial elements as either extruded sections or pre-cast elements. The architectural elements and sculptural aspects of the external facade are still in place and the internal and external fittings remain in situ.
