Places that tend not to sprawl and are built at a healthy density, are much more likely to be self-sustaining and nurture sustainable growth. Density is one of the most important conditions for independent economic activity, such as local shops and small businesses.
Dense neighbourhoods bring about proximity; crucial to sustaining everyday facilities, encouraging walking and a lower reliance on cars. They have also been shown to support both formal and informal networks for children and adults. Healthy density does not have to mean Tokyo style tower blocks, overcrowding or a lack of privacy. For instance, townhouses represent one popular example of medium-to-high density. This typology includes a garden, plenty of floorspace, noise-resistant walls, and reduced carbon footprint/energy bills - as they share heat between properties.
