Westwood includes 23 energy-efficient dwellings and the original farmhouse clustered around pedestrian commons and central common house. The common house is used for shared suppers, which are held twice a week, meetings and recreation. It has a playroom, lounge, laundry and guest rooms. In addition, there is a studio zone for several studios for residents whose work has low impact on the neighborhood. This leaves much of the land free for trees, gardens and play areas.
Parking is kept at the perimeter.
Westwood used Permaculture principles for the site design and early landscaping. Permaculture applies knowledge of natural ecosystems to design and maintain a harmonious integration of landscape and people. Westwood utilizes passive solar design, tight building envelopes for energy efficiency, centrally supplied hot water and radiant floor heating, landscaping for light and shade and multiple functions. Westwood welcomes people of different ages, family types, races, occupations, income levels, sexual orientations, religious beliefs. Common facilities and some dwellings are wheelchair-accessible.
