A sustainable approach to housing requires a re-evaluation of where residences are located, the materials used in their construction, the energy used to power them, and what activities they will accommodate. Many houses in the modern world are large private enclaves located in suburban areas isolated from work, commerce, industry, recreation and other activities. It does not appear that continuing to develop in this manner will be sustainable for any significant period of time.

NewVistas Model

Location, Location, Location

Evey resident of a NewVista village would be a short walk away from hundreds of businesses, and thousands of other residents. Every NewVistas home would be placed within a half mile of centrally located large multipurpose buildings where additional business activities, community governance, religious worship, recreation, and a range of other activites will take place. This all enables an enjoyable lifestyle with a very low impact. See our "Community Layout" page to learn more about how this works.

Residential Buildings

A NewVistas multi-family house is comprised of 4 flexible live-work units, all similarly configured. A live-work unit incorporates highly adaptive prefabricated modules and other standardized components. Three to six people would occupy one unit depending on their preferences, and each person would have their own personal 100 square foot space with lots of storage. The total measures 16.5 ft x 33 ft. Moving walls, 14-foot spans from floor to ceiling, innovative storage solutions, and other space transformation technologies allow live-work units to be both functional and comfortable.
