A custom home is a one-of-a-kind home that is designed for a specific client and for a particular location. The custom home builder may use plans created by an architect or by a professional home designer. Custom homes afford consumers the opportunity to control layout, lot size, and accessibility.
In most cases, custom home builders construct on land the home buyer already owns. Some developers sell fully serviced lots specifically for the construction of custom homes. This makes it easy to build a custom home since the lot is construction-ready and builders can focus purely on the design of the home.
