Getting into the premium home market is difficult
Construction companies have long specialized in the types of construction they do. This limits the amount of equipment they must purchase and the people they need to train. Some build roads, others choose to specialize in large commercial buildings. Construction companies that specialize in building homes have several options. They may opt to build neighborhoods for growing families, or single houses for their clients. Some choose the premium home market as their target.
Getting into the premium home market is often a difficult process. People with enough money to build mansions prefer to know their construction company has a long history of building premium homes. They would often rather wait to have their home built than go with an unknown company. If a builder can convince just one client to go with their company, they have gotten their foot in the door to become a premium home builder.
