In urban planning infill is the rededication of land in an urban environment, usually open-space, to new construction.[1] Infill also applies within an urban polity to construction on any undeveloped land that is not on the urban margin. The slightly broader term "land-recycling" is sometimes used instead. Infill has been promoted as an economical use of existing infrastructure and a remedy for urban sprawl.[2] Its detractors view it as overloading urban services, including increased traffic congestion and pollution, and decreasing urban green-space.[3][4]

In the urban planning and development industries, infill has been defined as the use of land within a built-up area for further construction, especially as part of a community redevelopment or growth management program or as part of smart growth.[5][6]

It focuses on the reuse and repositioning of obsolete or underutilized buildings and sites. This type of development is essential to renew blighted neighborhoods and to knit them back together with more prosperous communities.[7]

Redevelopment or land recycling is development that occurs on previously developed land. Infill buildings are constructed on vacant or underused property or between existing buildings.[8]

Urban Infill Projects can also be considered as a means of sustainable land development close to a city's urban core. Splitting lots off from existing properties is currently the most popular means of urban infill development. [9]

Suburban infill

Suburban infill is the development of land in existing suburban areas that was left vacant during the development of the suburb. It is one of the tenets of New Urbanism and smart growth, trends that urge densification to reduce the need for automobiles, encourage walking, and save energy ultimately.[13] In New Urbanism, an exception to infill is the practice of urban agriculture in which land in the urban or suburban area is retained to grow food for local consumption.

Infill housing

Infill housing is the insertion of additional housing units into an already-approved subdivision or neighborhood. They can be provided as additional units built on the same lot, by dividing existing homes into multiple units, or by creating new residential lots by further subdivision or lot line adjustments. Units may also be built on vacant lots.

Infill residential development does not require the subdivision of greenfield land, natural areas, or prime agricultural land, but it usually reduces green space. In some cases of residential infill, existing infrastructure may need expansion to provide enough utilities and other services: increased electrical and water usage, additional sewage, increased traffic control, and increased fire damage potential.

As with other new construction, structures built as infill may clash architecturally with older, existing buildings.
