A row house is a type of residential structure featuring single-family dwelling units that are attached to one another by common walls and typically have a uniform appearance from the front. Row houses are often found in urban areas and offer economical use of land while maintaining some of the privacy and freedom of a detached house.
A 'spec house' refers to a single-family dwelling constructed by a developer before having an identified buyer, based on the anticipation that the finished home will meet local market demand and sell within a reasonable period.
