Historically, and leading into 2026, Delaware's housing is defined by several distinct regional styles. In the northern, more urban areas like Wilmington, many residents live in brick rowhouses and "I-houses" that reflect Philadelphia's architectural influence. In rural and coastal Delaware, the most common historical form is the "I-house"—a structure two rooms wide and one room deep, often with a central hallway. However, as of 2026, the modern majority of Delawareans live in Colonial Revival or Cape Cod style single-family suburban homes. These were popular during the state's mid-century expansion and remain the dominant housing stock in New Castle and Kent counties. In the southern beach areas (Rehoboth, Lewes), there is a high concentration of "Coastal Contemporary" homes, often built on pilings or featuring large porches to accommodate the humid climate. Despite the state's small size, the contrast between the historic stone farmhouses of the Brandywine Valley and the modern modular homes of the southern farmlands represents a diverse architectural history rooted in both English and Quaker traditions.
