Arcology, a portmanteau of "architecture" and "ecology", is a vision of architectural design principles for very densely populated habitats. The concept has been primarily popularized, and the term itself coined, by architect Paolo Soleri. It also appears in science fiction. These structures have been largely hypothetical insofar as no 'arcology' envisioned by Soleri himself has yet been completed, but he posited that a completed arcology would provide space for a variety of residential, commercial, and agricultural facilities while minimizing individual human environmental impact. Arcologies are often portrayed in sci-fi as self-contained or economically self-sufficient.
An arcology is distinguished from a merely large building in that it is designed to lessen the impact of human habitation on any given ecosystem. It could be self-sustainable, employing all or most of its own available resources for a comfortable life: power; climate control; food production; air and water conservation and purification; sewage treatment; etc. An arcology is designed to make it possible to supply those items for a large population. An arcology would supply and maintain its own municipal or urban infrastructures in order to operate and connect with other urban environments apart from its own.
Arcology was proposed to reduce human impact on natural resources. Arcology designs might apply conventional building and civil engineering techniques in very large but practical projects in order to achieve pedestrian economies of scale that have proven, post-automobile, to be difficult to achieve in other ways.
Frank Lloyd Wright proposed an early version called Broadacre City although, in contrast to an arcology, Wright's idea is comparatively two-dimensional and depends on a road network. Wright's plan described transportation, agriculture, and commerce systems that would support an economy. Critics said that Wright's solution failed to account for population growth, and assumed a more rigid democracy than the U.S.A. actually has.
Paolo Soleri proposed later solutions, and coined the term 'arcology'. Soleri describes ways of compacting city structures in three dimensions to combat two-dimensional urban sprawl, to economize on transportation and other energy uses. Like Wright, Soleri proposed changes in transportation, agriculture, and commerce. Soleri explored reductions in resource consumption and duplication, land reclamation; he also proposed to eliminate most private transportation. He advocated for greater "frugality" and favored greater use of shared social resources, including public transit (and public libraries).
Similar real-world projects
Arcosanti is an experimental "arcology prototype" - a demonstration project under construction in central Arizona. Designed by Paolo Soleri, its primary purpose is to demonstrate Soleri's personal designs, his application of principles of arcology to create a pedestrian-friendly urban form.
Many cities in the world have proposed projects adhering to the design principles of the arcology concept, like Tokyo, and Dongtan near Shanghai. The Dongtan project may have collapsed, and it failed to open for the Shanghai World Expo in 2010.
Certain urban projects reflect arcology principles. Pedestrian connection systems often provide a wide range of goods and services in a single structure. Some examples include the +15 system in downtown Calgary, Montréal’s RÉSO or the Minneapolis Skyway System and The Windscreen in Fermont, Quebec. They include supermarkets, malls and entertainment complexes. The +15 is the world's most extensive skywalk, at 16 km (9.9 mi) in total length. Minneapolis has the longest single path, at 13 km (8 mi). Seward's Success, Alaska was never built, but would have been a small city just outside of Anchorage. Chicago has a sizeable tunnel system known as the Chicago Pedway connecting a portion of the buildings in the Chicago Loop.
The Las Vegas Strip has many arcology features to protect people from the 45 °C (113 °F) heat. Many major casinos are connected by tunnels, footbridges, and monorails. It is possible to travel from Mandalay Bay at the south end of the Strip to the Las Vegas Convention Center, three miles (5 km) to the north, without using streets. In many cases, it is possible to travel between several different casinos without ever going outdoors. It is possible to live in this complex without need to venture outside, except the Strip has not generally been considered self-sustainable. Soleri did not advocate for enclosed cities, although he did sketch a design and build a model of an 'arcology' for outer space.
The Toronto downtown area features an underground pedestrian network, PATH. Multiple high-rises are connected by a series of underground tunnels. It is possible to live in this complex without needing to venture outside, but the PATH network is not self-sustaining, nor is it presently self-sustainable. The total network spans 28-kilometres (17 mi).
McMurdo Station of the United States Antarctic Program and other scientific research stations on the continent of Antarctica resemble the popular conception of an arcology as a technologically advanced, relatively self-sufficient human community. The Antarctic research base provides living and entertainment amenities for roughly 3,000 staff who visit each year. Its remoteness and the measures needed to protect its population from the harsh environment give it an insular character. The station is not self-sufficient — the U.S. military delivers 30,000 cubic metres (800,000 US gal) of fuel and 5 kilotonnes (11 million pounds) of supplies and equipment yearly through its Operation Deep Freeze resupply effort — but it is isolated from conventional support networks. The base generates electricity with its own power plant, and grows fruits and vegetables in a hydroponic green house when resupply is non-existent. Under international treaty, it must avoid damage to the surrounding ecosystem.
The Begich Towers operates like a small-scale arcology encompassing nearly all of the population of Whittier, Alaska. The pair of buildings contains residential housing as well as a school, grocery, and municipal offices Whittier once boasted a second structure known as the Buckner Building. The Buckner Building still stands but was deemed unfit for habitation after the 1969 earthquake. 
In popular culture
Most proposals to build real arcologies have failed due to financial, structural or conceptual shortcomings. Arcologies are therefore found primarily in fictional works. One significant example is the novel Oath of Fealty by Larry Niven and Jerry Pournelle. In the novel, a segment of the Los Angeles population has moved into an arcology. The plot examines the social changes that result, both inside and outside the arcology. Thus the arcology is presented not just as a plot device but as a subject of critique.

Role-playing and table-top games
- In the table-top strategy game Warhammer 40,000, hyperstructures, called "hives," are extremely common and are the main method of housing large populations in the billions. Arcologies are so widespread that some planets, dubbed 'hive worlds', are constructed entirely of hyperstructures. Necromunda, an offshoot game set in the Warhammer 40,000 universe, involves conflict between rival gangs on the hive world of Necromunda.
- In the RPG Shadowrun, a number of hyperstructures such as the "Renraku Arcology" exist by 2050, most of which are mega-corporate controlled. A major theme to these is the desire of a large corporation to control every aspect of its employees' lives. A major meta-plot element was the sealing off of the aforementioned Renraku Arcology in Seattle when the advanced computer control system awakened into a self-aware AI named Deus.
- In the RPG Trinity, a number of hyperstructures exist, with the largest being that of the New New York Arcology run by the Psi-Order Orgotek.
- In the Rifts RPG, the capital of the Coalition States is the city of Chi-Town. Along with some of the other major Coalition cities, Chi-Town is considered a "Mega-City" in that its entire population is housed inside one giant structure consisting of more than thirty levels, each of which are several stories high and contain a number of sub-levels.

The only known vaults to be completely running 200 years after the bombs dropped are Vault 101, located in Washington DC, and Vault 21, Located in Las Vegas, Nevada.
