Principles
The neighbourhood unit was conceived of as a comprehensive physical planning tool, to be utilised for designing self-contained residential neighbourhoods which promoted a community centric lifestyle, away from the "noise of the trains, and out of sight of the smoke and ugliness of industrial plants" emblematic of an industrialising New York City in the early 1900s.
The core principles of Perry's Neighbourhood Unit were organised around several physical design ideals:
"Centre the school in the neighbourhood so that a child's walk to school was only about one-quarter of a mile and no more than one half mile and could be achieved without crossing a major arterial street. Size the neighbourhood to sufficiently support a school, between 5,000 to 9,000 residents, approximately 160 acres at a density of ten units per acre. Implement a wider use of the school facilities for neighbourhood meetings and activities, constructing a large play area around the building for use by the entire community.
Place arterial streets along the perimeter so that they define and distinguish the "place" of the neighborhood and by design eliminate unwanted through-traffic from the neighborhood. In this way, major arterials define the neighborhood, rather than divide it through its heart.
Design internal streets using a hierarchy that easily distinguishes local streets from arterial streets, using curvilinear street design for both safety and aesthetic purposes. Streets, by design, would discourage unwanted through traffic and enhance the safety of pedestrians.
Restrict local shopping areas to the perimeter or perhaps to the main entrance of the neighborhood, thus excluding nonlocal traffic destined for these commercial uses that might intrude on the neighborhood.
Dedicate at least 10 percent of the neighborhood land area to parks and open space, creating places for play and community interaction"
The neighbourhood unit was embraced for its community idealism, and many of the public sectors in those countries which were exposed to the theorem have since adopted its purpose; of protecting and promoting the public health and of considering the safety and welfare of citizens. Furthermore, private developers and investors continue to construct and fund planned communities based upon many of the concepts tenets, due to consumer demand for the idealistic community intimacy associated with living with heteronormative homo reciprocans of similar socioeconomic status. These attractive qualities of the concept of the neighbourhood unit are referred to by Allaire, "as reflecting a nostalgia for rural living".

Famous quotes containing the word principles:
“I have ever deemed it fundamental for the United States never to take active part in the quarrels of Europe. Their political interests are entirely distinct from ours. Their mutual jealousies, their balance of power, their complicated alliances, their forms and principles of government, are all foreign to us. They are nations of eternal war.”
—Thomas Jefferson (1743–1826)
“All those who write either explicitly or by insinuation against the dignity, freedom, and immortality of the human soul, may so far forth be justly said to unhinge the principles of morality, and destroy the means of making men reasonably virtuous.”
—George Berkeley (1685–1753)
“That, upon the whole, we may conclude that the Christian religion not only was at first attended with miracles, but even at this day cannot be believed by any reasonable person without one. Mere reason is insufficient to convince us of its veracity: And whoever is moved by Faith to assent to it, is conscious of a continued miracle in his own person, which subverts all the principles of his understanding, and gives him a determination to believe what is most contrary to custom and experience.”
—David Hume (1711–1776)
