the maison de verre (french for house of glass) was built from 1928 to 1932 in paris, france. constructed in the early modern style of architecture, the house's design emphasized three primary traits: honesty of materials, variable transparency of forms, and juxtaposition of "industrial" materials and fixtures with a more traditional style of home décor. the primary materials used were steel, glass, and glass block. some of the notable "industrial" elements included rubberized floor tiles, bare steel beams, perforated metal sheet, heavy industrial light fixtures, and mechanical fixtures.
