Kitchen cabinet
Cabinet doors may feature a variety of materials such as wood, metal or glass. Wood may be solid wood ("breadboard" construction) or engineered wood or may be mixed (e.g. engineered wood panel in a solid wood frame)
Frankfurt kitchen
Most Frankfurt kitchens were thrown away in the 1960s and 1970s, when modern kitchens with easy to clean surfaces like "Resopal" were affordable. Often only the aluminium drawers survived, which aren't typical of a modern kitchen. They were also sold separately for a few years by Haarer, the manufacturing company and chosen by architects and cabinet makers for their furniture.
