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 (e.g., tables with no visual barriers) reduce short-term building costs, compared to cubicles or private offices, but result in persistently lower productivity, dramatically fewer face-to-face interactions among staff, and a higher number of sick days.{{Cite journal |last1=Bodin Danielsson |first1=Christina |last2=Chungkham |first2=Holendro Singh |last3=Wulff |first3=Cornelia |last4=Westerlund |first4=Hugo |date=2014-02-01 |title=Office design's impact on sick leave rates |url=https://www.tandfonline.com/doi/full/10.1080/00140139.2013.871064 |journal=Ergonomics |language=en |volume=57 |issue=2 |pages=139–147 |doi=10.1080/00140139.2013.871064 |pmid=24460745 |issn=0014-0139|url-access=subscription }} An open office plan may have permanently assigned spaces at a table, or it may be used as a flex space or hot desking program.
In residential design, open plan or open concept (the term used mainly in Canada)[http://dictionary.reference.com/browse/open-concept Definition of open-concept] at Dictionary.com 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.
Homes

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, shop houses, and Inn houses with rent employed owner-occupants. For example in pre-plague London England. After the plague owners of houses in London added rooms. These rooms began to be labeled with a name and a furnishing practice.{{cite book |author1=Katherine L.

In the 1880s middle class suburban houses for families replaced small public rooms of the home with specific functions with larger rooms that fulfilled multiple uses. Walls were abolished or replaced with archways that had glass doors or sliding doors. 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.{{cite book |last=Ward|first=Peter |title=A History of Domestic Space: Privacy and the Canadian Home |date=2011 |publisher=UBC Press |isbn=9780774841825 |pages=37}}
Frank Lloyd Wright was one of the early advocates for open plan design in houses,{{cite book|last1=Schwartz |first1=Tony |last2=Gomes |first2=Jean |last3=McCarthy |first3=Catherine |title=Be Excellent at Anything: The Way We're Working Isn't Working |date=2010 |publisher=Simon and Schuster |isbn=9781451639452 |pages=224}} expanding on the ideas of Charles and Henry Greene and shingle style architecture.{{cite journal|title=Breaking Down Walls|journal=Old-House Journal|last=Elliott|first=Lynn|url=https://books.google.com/books?id=fuAAoicT8rkC&pg=PA50|access-date=1 June 2014|date=May–June 2002|publisher=Active Interest Media Inc.|pages=50–53}} 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."{{cite book|last=Schoenauer |first=Norbert |title=6,000 Years of Housing |date=2000 |publisher=W.W. Norton |isbn=9780393731200 |pages=384}} 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.
In the late 2010s, the open plan design became less 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.{{Cite web |url=https://www.bostonglobe.com/metro/2019/03/06/miss-walls-cry-for-help-from-woman-living-home-with-open-floor-plan/qLl9QX8REvsQ5gKmaeCvFL/story.html |title=People in open-concept homes are realizing the walls were there for a reason |publisher=The Boston Globe }} 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).[https://www.citylab.com/design/2018/08/the-case-for-rooms/563216/ The Case for Rooms] 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.{{Cite web |url=http://www.housebeautiful.co.uk/decorate/kitchen/news/a134/the-new-home-trend-two-kitchens/ |title=The new home trend: two kitchens |date=August 14, 2014 |publisher=House Beautiful}}
Office spaces
= Development of open-plan workspace types =
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.Duffy, F. (1997). The new office. London Conran Octopus 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.{{Cite web |last=Musser |first=George |title=The Origin of Cubicles and the Open-Plan Office |url=https://www.scientificamerican.com/article/the-origin-of-cubicles-an/ |access-date=2024-10-15 |website=Scientific American |language=en}} 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.Gillen, N. M. (2006).

Chichester, UK: Wiley. {{doi|10.1002/9781119992592.ch6}} Some companies experimented with designs that provided 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"{{Cite web|url=http://instruct1.cit.cornell.edu/courses/dea453_653/01students/zach_jason/|title=Cornell study}} and "hot desking".

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.{{citation|url= http://www.news.qut.edu.au/cgi-bin/WebObjects/News.woa/wa/goNewsPage?newsEventID=23175 |title= Why your office could be making you sick |author= Vinesh Oommen |work= Asia-Pacific Journal of Health Management |date= 13 Jan 2009 |url-status= dead |archive-url= https://web.archive.org/web/20090218071604/http://www.news.qut.edu.au/cgi-bin/WebObjects/News.woa/wa/goNewsPage?newsEventID=23175 |archive-date= February 18, 2009 }}
The noise level in open-plan offices greatly reduces productivity. Productivity in an open-office plan has been estimated to be one-third what the same workers would achieve in quiet rooms.{{cite web

One study found employees were less likely to share their views on phone calls in open offices, because they worry that their co-workers will overhear them and judge them negatively.{{Cite web |last=Wertz |first=Jia |title=Open-Plan Work Spaces Lower Productivity And Employee Morale |url=https://www.forbes.com/sites/jiawertz/2019/06/30/open-plan-work-spaces-lower-productivity-employee-morale/ |website=Forbes}} Employees worry that speaking out loud will distract their co-workers.
Some design goals of open plan offices include letting everyone see what everyone else is doing at any given moment, reducing information silos by letting everyone overhear what everyone else is saying, and flattening organizational hierarchies.{{Cite web|url=https://www.adventureassoc.com/open-office-plans-the-advantages-disadvantages-and-research/|title=Open Office Plans: Advantages, Disadvantages, & Research|date=June 4, 2015|website=Adventure Associates}}
