Spacious Adam/Federal house plans present a balanced, often brick, facade to the street, usually in two or more stories.
The center hall entry features both sidelights and a fanlight overhead, as well as a pediment or portico supported by columns. Rooflines can be gabled with little overhang, although larger versions sometimes feature a hipped roof topped by a decorative balustrade. The interior design reflects the home's exterior symmetry, with large open rooms well-lit by numerous windows. The modern Federal style house abounds with extra storage space and work areas, boosting the flexibility of an often formal and symmetrical interior design.
