8. Brownfield sites Greenfield sites Derelict sites in urban areas New sites, usually on agricultural land in greenbelts around urban areas The land is available but can be costly to reclaim if it has been polluted by industrial use; this information may not be readily available Land is not available unless planning permission has been obtained; there is usually a public enquiry and a delay of several years, adding to the costs Housing is likely to be built at a high density to reflect the high cost of land Housing will be relatively low density – there is high demand for such housing Infrastructure is already present, though existing facilities could becomes overloaded Infrastructure costs are high as new sewerage, water, gas and electricity supplies have to be considered; new schools and health facilities may be needed too Sites tend to be small patches of land Sites tend to be larger The environment is generally improved, especially visually The environment is changed from rural to urban use
