Brownfield sites

• Are often on disused or derelict land.
• Are more available in the North and Midlands (but most housing demand is in the south east).
• Are valuable as existing buildings can be split up into more homes on any one site.
• The site has already been developed so reduces urban sprawl.
• Use unsightly areas for building developments, so improves the urban environment.
• Are found in urban areas, so building housing there reduces demand on car use.
• Are more expensive to build on as often the land needs to be cleared first (especially if land is contaminated from previous industrial use).
