Executive home is a marketing term for a moderately large and well-appointed house. Such houses were formerly described as mansionettes or bijou residences. The word mansion historically denotes homes with more character or uniqueness than an average executive home. This is because executive homes are usually constructed among homes of very similar size and type by a subdivider on speculation; they are generally built en-masse by development companies to be marketed as premium real estate. Executive homes can differ from traditional mansions mostly in their parcel size, since many of these newer homes are built on increasingly small lots so developers can maximize available acreage.
