Which community concept involves every family receiving one acre of land with complete amenities?

The correct choice refers to the concept of Broadacres, which was articulated by the planner Frank Lloyd Wright in the early 20th century. In this concept, every family receives one acre of land, allowing for individual ownership that encourages a sense of autonomy and self-sufficiency. This model emphasizes the importance of green spaces, where families can engage in gardening and agriculture, promoting a direct relationship between the individual and the land.

Broadacres also ensures that each plot is equipped with complete amenities, signifying that the community is designed to provide all essential services and facilities within a manageable distance. This layout supports a suburban lifestyle while still fostering community engagement and connection to nature.

In contrast, New Urbanism focuses on higher density living and walkable neighborhoods, Garden Cities emphasize a blend of urban and rural living with a focus on green belts and limited land use, and Live-Work Units integrate residential and workspace but do not emphasize allotting acre-sized parcels of land for every family. Understanding these different community concepts clarifies the unique aspects of Broadacres and why it aligns with the specific characteristics detailed in the question.
