Usonian

ユーソニアン住宅 / 1930s–1950s / Style / Modern Architecture

Frank Lloyd Wright's approach to a simpler American home from the 1930s onward. Low roofs, natural materials and connected living spaces open toward a garden while controlling exposure to the street. It shares the Prairie School's horizontal emphasis, but puts the economy of a smaller dwelling and everyday life at its centre.

Dictionary entry

Type
Keep signage small and related to material joints; avoid a heraldic front.
Composition
Connect the living areas beneath one low roof and open long glazed edges toward the garden.
Material
Let timber grain, brick and repeated joints provide character beside transparent glass.
Caution
Timber and big windows alone do not make a Usonian house. Distinguish the original affordability goal from later growth in scale and cost; structural details require specialist validation.
