The most sustainable places to build are existing neighborhoods where the utility infrastructure is already in place for new homes and businesses. Sustainable neighborhoods are liveable and walkable, with easy access to public transportation, local shopping and services. Sustainable neighborhoods also provide a range of housing options for all stages of life and many lifestyles, and have passive and active recreational spaces to support interactive communities. Right-Sized Homes identifies sustainable development opportunities in these neighborhoods, and helps existing communities implement their plans to increase the sustainability of their neighborhood.
