In which type of house would you likely find an expanded attic?

An expanded attic is typically found in a one-and-one-half story house. This type of house design features a full story and an additional half story, often resulting in a sloped roof that creates a usable space in the attic. The design allows for extra bedrooms or living space under the roof, taking advantage of the vertical space while still providing a functional attic area.

In contrast, a two-story house generally has two complete levels without the characteristics of an expanded attic, as the configuration is more straightforward with full height on both stories. A split-level house has distinct levels that are staggered instead of utilizing the roof space for an attic, making it less likely to feature an expanded attic. A one-story house, by definition, has a single level and typically will not have an attic that could be classified as expanded, as there is no additional height above the main living areas.

Thus, the architectural design of the one-and-one-half story house is what specifically accommodates an expanded attic, differentiating it from the other options.
