Open plan is the generic term used in architectural and interior design for any floor plan that makes use of large, open spaces and minimizes the use of small, enclosed rooms such as private offices. The term can also refer to landscaping of housing estates, business parks, etc., in which there are no defined property boundaries, such as hedges, fences, or walls.
Open-plan office designs are generally promoted as improving collaboration, however some studies have suggested that moving from cubicles to open workspaces (e.g., tables with no visual barriers) actually results in dramatically fewer face-to-face interactions among staff and reduced productivity.
In residential design, open plan or open concept (the term used mainly in Canada) describes the elimination of barriers such as walls and doors that traditionally separated distinct functional areas, such as combining the kitchen, living room, and dining room into a single great room.
Many pre-industrial homes were huts that consisted of a single room, but this was usually small. Already in the Middle Ages, however, there were some single-room hearth-heated hall houses, for example in England, that were large enough so they could develop into multi-room houses. Multi-room houses however didn't become popular until later when the country industrialized, as a result of which more people could afford them.
In the 1880s,[clarification needed] small public rooms of the home with specific functions began to be replaced by larger rooms that fulfilled multiple uses, but kitchens, bedrooms, and bathrooms remained enclosed private spaces. Larger rooms were made possible by advances in centralized heating that allowed larger spaces to be kept at comfortable temperatures.
Frank Lloyd Wright was one of the early advocates for open plan design in houses, expanding on the ideas of Charles and Henry Greene and shingle style architecture. Wright's designs were based on a centralized kitchen open to other public spaces of the home where the housewife could be "more hostess 'officio', operating in gracious relation to her home, instead of being a kitchen mechanic behind closed doors." Not having a dividing wall between the kitchen and a combined living-dining room became more popular especially in the United States in the 1970s.
A home with this type of layout has one or more large, open rooms that function as multiple rooms within a single living space. The most common design is a great room that combines the kitchen, dining room, and living room into one shared space. Such floor plans usually work well in homes with a smaller area, while larger homes have more leeway to work with[clarification needed] when integrating great rooms into a floor plan. The removal of interior walls increases views and allows sunlight from windows in the exterior walls to spread throughout the house.
In the late 2010s, disapproval of the open plan design has become more common. Complaints about open plan designs include that they make it more difficult for different people to engage in different activities and make it difficult to hide clutter or a dirty kitchen. Walls are useful to contain noise and smells and to provide privacy, and small rooms are more efficient to heat and cool (especially when kitchen appliances are in use). A follow-on trend among relatively wealthy homeowners is to build a second "mess kitchen" where the actual activity of food preparation takes place, while entertaining happens in a clean kitchen that is part of the open concept space.
Development of open-plan workspace typesEdit
Prior to the 1950s open-plan offices mostly consisted of large regular rows of desks or benches where clerks, typists, or technicians performed repetitive tasks. Such designs were rooted in the work of industrial engineers or efficiency experts such as Frederick Winslow Taylor and Henry Ford. In the 1950s a German team named Quickborner developed the office landscape, which used conventional furniture, curved screens, large potted plants, and organic geometry to create work groups on large, open floors. Office landscape was quickly supplanted by office-furniture companies which developed cubicles based on panel-hung or systems furniture. Many terms (mostly derisive) have been used over time for offices using the old-style, large arrays of open cubicles.
An increase in knowledge work and the emergence of mobile technology during the late 20th-century led to an evolution in open-plan offices. Many[quantify] companies have started experimenting with designs which provide a mix of cubicles, open workstations, private offices, and group workstations. In some cases, these are not assigned to one particular individual, but are available to any employee of the company on either a reservable or "drop-in" (first come, first served) basis. Terms for this strategy include hoteling, "alternative officing" and "hot desking".
Michael Bloomberg used a team-oriented bullpen style – where employees can see and hear each other freely, but desks are grouped into teams – at his media company Bloomberg L.P. and for his staff while Mayor of New York City (in office: 2002–2013).
A systematic survey of research upon the effects of open-plan offices found frequent negative effects in some traditional workplaces: high levels of noise, stress, conflict, high blood pressure and a high staff turnover.
The noise level in open-plan offices greatly reduces productivity, which drops to one third relative to what it would be in quiet rooms. New technologies like voice-activation and mobile phones also decrease effectiveness in the open-plan setting.
Some design goals of open plan offices include transparency (everyone can see what everyone else is doing at any given moment), overcoming social silos, flattening organizational hierarchies One study found employees reduced sharing of honest opinions while on phone calls in open offices because co-workers can overhear them.
Although promoted as a way to encourage collaboration, speed decision-making, and increase the group's collective intelligence, open-plan offices result in a dramatic reduction in face-to-face interactions, as employees turn to digital communication, such as sending e-mail messages. Open-plan offices have frequently[quantify] been found to reduce the confidential or private conversations which employees engage in, and to reduce job satisfaction, concentration and performance, whilst increasing auditory and visual distractions.[need quotation to verify]
Open-plan offices have been found to elevate the risk of employees needing to take time off for sickness. Health considerations such as COVID-19 may militate against working in open-plan offices.
