As architecture, along with other professions, woke up to social responsibility, the non-profit CDCs began to provide architectural and planning services for the disadvantaged, usually in urban areas. At any rate, by the late 1960's it became clear that the market for non-profit design services was larger than originally thought and extended beyond minorities to many segments of society. The clinic may be in a school of architecture or exist as a separate but related institution. Successful CDCs are now operating at several schools. Although many are located in large urban areas, rural problems deserve equal attention, and the challenge has been taken up wherever resources permit.
Architecture currently continues to increase in complexity.
Projects in general are larger, often involving greater areas of land. The nature of the client is also changing. In the old days even very large projects were identified with single clients-individuals whose intentions and needs could easily be made clear. Today's client is more likely to be a board of directors or trustees, a special committee, or representatives of a government agency. There are also many new technological developments, such as automatic control systems for air conditioning, complicated structural systems for long spans, and elaborate factory prefabrication.
