If you desire a luxury home, you don't necessarily have to build big. While our collection of luxury house plans includes plenty of estate-sized homes with two or more levels of living space and plenty of room for guests, you'll also find luxury home plans that come in smaller designs. The devil is in the details, as they say, and a luxury home will offer plenty of exquisite architectural details. The exterior of a luxury floor plan, for example, will be beautiful and faithful to the home’s style. Inside a luxury house plan, the design will be unique, organized and include thoughtfully planned focal points, views to the outside, and decorative ceilings.
