In the 1980s, there was a backlash against industrial kitchen planning and cabinets with people installing a mix of work surfaces and free standing furniture, led by kitchen designer Johnny Grey and his concept of the "unfitted kitchen". Modern kitchens often have enough informal space to allow for people to eat in it without having to use the formal dining room. Such areas are called "breakfast areas", "breakfast nooks" or "breakfast bars" if the space is integrated into a kitchen counter. Kitchens with enough space to eat in are sometimes called "eat-in kitchens". During the 2000s, flat pack kitchens were popular for people doing DIY renovating on a budget. The flat pack kitchens industry makes it easy to put together and mix and matching doors, bench tops and cabinets. In flat pack systems, many components can be interchanged.
