There have been numerous times throughout history when houses were built alike, and it was often done as a way to save money. Some of those buildings were originally owned by companies. Their purpose was to house workers and their families, and saving money in the construction was important. Other times houses were built alike for families seeking affordable houses, and the same need for lower cost was an issue.
While it was important to assure people they could have a place to live, many were often struck by the lack of charm or personality of their homes. They often passed that wish down to their children. Many looking for their own homes today are more interested in purchasing a unique home, and converting old buildings is often one of the choices they make. It can work out well if the building is in good condition, but they may face some difficult decisions along the way.
