By the 1960s construction had subsided significantly and developers began building different kinds of plans to try and accommodate the changes in the market. Those who had taken advantage of the suburbanization trend in he post-war years had seen the value of their real estate increase dramatially and many were anxious to re-invest their assets. In an effort to reap this affluence, certain contractors moved away from the standard models and began designing larger buildings on increasingly spacious parcels even farther from city centers. Other builders began working on home to meet the needs of young couples starting new families. The townhouse, a two to three-story brick and frame structure containing more than 4 but less than 30 units per structure, wa seen as the solution. These aprtments were successful in luring many young adult city dwellers out to the suburbs.
In subsequent development, traditional single family ranch-style designs continued to be embraced, but new forms were also introduced: The condominium, a singlefamily attached dwelling; the triplex and fourplex, three-and four-family struchres; and prefabs, which have become significantly more popular durin the last 20 years owing to their low cost and ease of construction. The prefabs have the additional distinction of being mobile. It is not uncommon to see semi-trailers hauling these modular living units along the freeways to remote destinations. In a very real sense, this phenomena marks the cutting edge of suburbanization: a move out of the traditional suburbs and into areas that were formally considered wildeness.
