Local planning authorities should plan positively for new development, and approve all individual proposals wherever possible."
"strong, vibrant and healthy communities, by providing an increased supply of housing to meet the needs of present and future generations; and by creating a good quality built environment, with accessible local services, that reflects community needs and supports well-being" Planning, building and the environment (March 2011)
