Permeable new housing development promotes the establishment of sustainable movement patterns. In the revised and more focused national housing design standard; Building for Life 12 a significant improvement was the moving of the question “Does the scheme integrate with existing, roads, paths and surrounding development?” from the 14th to the 1st consideration for new housing development.
Achieving a design that meets this recommendation can be frustrating for developers as often the ability to make this happen rests with local authorities and existing communities. It is quite common for example for existing communities to resist the use of footpaths by new development so that the same route has to be (less well) duplicated. Frequently new developments are created as giant cul de sacs – internally well connected but detached from their surroundings and unlikely to encourage sustainable patters of movement. In effect adding traffic to existing networks that local communities will also have sought to resist.
That this lack of connectivity is something quite common to current patterns of development was borne out by the transport planner Phil Jones in his review for the Urban Design Group of how well the design principles of Manual for Streets 2 are being embedded in current practice – http://www.urbannous.org.uk/manual-for-streets.htm – His view is slowly especially at the macro or strategic scale of development. Creating good connectivity requires a clear strategic vision about the integration of new homes from the local authority so that stakeholders and neighboring landowners can be encouraged to work together to link developments.
