In spite of the general economic decline, office space has tended to increase. This is due to the fact that the building process itself has become a major source of profit; it is now an ultimate goal and no longer a means. However, proliferation of office space has serious effects on a community. Districts which are of interest to the office market are withdrawn from small owners and from the former use by their inhabitants; inhabitants are confronted with expulsion; houses decay; remaining residents have long-term building and construction yards "on their doorsteps"; and when the offices are finally completed, there are resultant heavy traffic flows and parking problems.
