Homes of the wealthy had the kitchen as a separate room, usually next to a bathroom (so that both rooms could be heated by the kitchen fire), both rooms being accessible from the court. In such houses, there was often a separate small storage room in the back of the kitchen used for storing food and kitchen utensils.

Middle Ages

Early medieval European longhouses had an open fire under the highest point of the building. The "kitchen area" was between the entrance and the fireplace. In wealthy homes there was typically more than one kitchen. In some homes there were upwards of three kitchens. The kitchens were divided based on the types of food prepared in them. In place of a chimney, these early buildings had a hole in the roof through which some of the smoke could escape. Besides cooking, the fire also served as a source of heat and light to the single-room building. A similar design can be found in the Iroquois

, kitchens in Europe lost their home-heating function even more and were increasingly moved from the living area into a separate room. The living room was now heated by tiled stoves, operated from the kitchen, which offered the huge advantage of not filling the room with smoke.

Freed from smoke and dirt, the living room thus began to serve as an area for social functions and increasingly became a showcase for the owner's wealth. In the upper classes, cooking and the kitchen were the domain of the servants, and the kitchen was set apart from the living rooms, sometimes even far from the dining room. Poorer homes often did not have a separate kitchen yet; they kept the one-room arrangement where all activities took place, or at the most had the kitchen in the entrance hall.

In a few European farmhouses, the smoke kitchen was in regular use until the middle of the 20th century. These houses often had no chimney, but only a smoke hood above the fireplace, made of wood and covered with clay, used to smoke meat. The smoke rose more or less freely, warming the upstairs rooms and protecting the woodwork from vermin.

The middle class tried to imitate the luxurious dining styles of the upper class as best as it could. Living in smaller apartments, the kitchen was the main room—here, the family lived. The study or living room was saved for special occasions such as an occasional dinner invitation.

Gas pipes were first laid in the late 19th century, and gas stoves started to replace the older coal-fired stoves. Gas was more expensive than coal, though, and thus the new technology was first installed in the wealthier homes. Where workers' apartments were equipped with a gas stove, gas distribution would go through a coin meter.

In rural areas, the older technology using coal or wood stoves or even brick-and-mortar open fireplaces remained common throughout. Gas and water pipes were first installed in the big cities; small villages were connected only much later.

 conservatism coupled with economic reasons prevailed. The kitchen once more was seen as a work place that needed to be separated from the living areas. Practical reasons also played a role in this development: just as in the bourgeois homes of the past, one reason for separating the kitchen was to keep the steam and smells of cooking out of the living room.

Unit/fitted

Poggenpohl led innovation in the kitchen area by presenting the "reform kitchen" in 1928 with interconnecting cabinets and functional interiors. The reform kitchen was a forerunner to the later unit kitchen and fitted kitchen. Poggenpohl presented the form 1000, the world's first unit kitchen, at the imm Cologne

The idea of standardized dimensions and layout developed for the Frankfurt kitchen took hold while Poggenpohl began exporting to neighboring countries which for the first time required a kitchen specifier known today as a kitchen designer. The equipment used remained a standard for years to come: hot and cold water on tap and a kitchen sink and an electrical or gas stove and oven. Not much later, the refrigerator

 was added as a standard item. The concept was refined in the "Swedish kitchen" using unit furniture with wooden fronts for the kitchen cabinets. Soon the concept was amended by the use of smooth synthetic door and drawer fronts, first in white, recalling a sense of cleanliness and alluding to sterile lab or hospital settings, but soon after in more lively colors, too.

 for low-price, high-tech consumer goods led to Western European kitchens being designed to accommodate new appliances such as refrigerators and electric/gas cookers.

Parallel to this development in tenement buildings was the evolution of the kitchen in homeowner's houses. There, the kitchens usually were somewhat larger, suitable for everyday use as a dining room, but otherwise the ongoing technicalization was the same, and the use of unit furniture also became a standard in this market sector.

 viewed cooking as a mere necessity, and women should work "for the society" in factories, not at home. Also, housing had to be built at low costs and quickly, which led directly to the standardized apartment block using prefabricated slabs. The kitchen was reduced to its minimums and the "work kitchen" paradigm taken to its extremes: in East Germany for instance, the standard tenement block of the model "P2" had tiny 4 m² kitchens in the inside of the building (no windows), connected to the dining and living room of the 55 m² apartment and separated from the latter by a pass-through or a window.

 allowed an open kitchen again, integrated more or less with the living room without causing the whole apartment or house to smell. Before that, only a few earlier experiments, typically in newly built upper middle class family homes, had open kitchens. Examples are Frank Lloyd Wright

The re-integration of the kitchen and the living area went hand in hand with a change in the perception of cooking: increasingly, cooking was seen as a creative

 and sometimes social act instead of work. And there was a rejection by younger home-owners of the standard suburban model of separate kitchens and dining rooms found in most 1900-1950 houses. Many families also appreciated the trend towards open kitchens, as it made it easier for the parents to supervise the children while cooking and clear up spills. The enhanced status of cooking also made the kitchen a prestige object for showing off one's wealth or cooking professionalism. Some architect

s have capitalized on this "object" aspect of the kitchen by designing freestanding "kitchen objects". However, like their precursor, Colani's "kitchen satellite", such futuristic designs are exceptions.

Another reason for the trend back to open kitchens (and a foundation of the "kitchen object" philosophy) is changes in how food is prepared. Whereas prior to the 1950s most cooking started out with raw ingredients and a meal had to be prepared from scratch, the advent of frozen meals and pre-prepared convenience food

 changed the cooking habits of many people, who consequently used the kitchen less and less. For others, who followed the "cooking as a social act" trend, the open kitchen had the advantage that they could be with their guests while cooking, and for the "creative cooks" it might even become a stage for their cooking performance.
The "Trophy Kitchen" is highly equipped with very expensive and sophisticated appliances which are used primarily to impress visitors and to project social status, rather than for actual cooking.

 was founded in 1944 with the goal to improve the state of the art in home building, originally with an emphasis on standardization for cost reduction. It was there that the notion of the kitchen work triangle
Kitchen Work Triangle

was formalized: the three main functions in a kitchen are storage, preparation, and cooking (which Catharine Beecher had already recognized), and the places for these functions should be arranged in the kitchen in such a way that work at one place does not interfere with work at another place, the distance between these places is not unnecessarily large, and no obstacles are in the way. A natural arrangement is a triangle

, with the refrigerator, the sink, and the stove at a vertex each.

This observation led to a few common kitchen forms, commonly characterized by the arrangement of the kitchen cabinets and sink, stove, and refrigerator:
  • A single-file kitchen (or one-way galley) has all of these along one wall; the work triangle degenerates to a line. This is not optimal, but often the only solution if space is restricted. This may be common in an attic space that is being converted into a living space, or a studio apartment.
  • The double-file kitchen (or two-way galley) has two rows of cabinets at opposite walls, one containing the stove and the sink, the other the refrigerator. This is the classical work kitchen.
  • In the L-kitchen, the cabinets occupy two adjacent walls. Again, the work triangle is preserved, and there may even be space for an additional table at a third wall, provided it does not intersect the triangle.
  • A U-kitchen has cabinets along three walls, typically with the sink at the base of the "U". This is a typical work kitchen, too, unless the two other cabinet rows are short enough to place a table at the fourth wall.
  • The block kitchen (or island) is a more recent development, typically found in open kitchens. Here, the stove or both the stove and the sink are placed where an L or U kitchen would have a table, in a freestanding "island", separated from the other cabinets. In a closed room, this does not make much sense, but in an open kitchen, it makes the stove accessible from all sides such that two persons can cook together, and allows for contact with guests or the rest of the family, since the cook does not face the wall anymore. Additionally, the kitchen island's countertop can function as an overflow-surface for serving buffet style meals or sitting down to eat breakfast and snacks.

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
