Which development is characterized by early planned unit developments with all amenities in one compound?

Barbican development is recognized for its distinctive approach to urban planning, most notably in the context of the Barbican Estate in London, which was conceived in the post-World War II era. This model of development is characterized by its integration of residential, cultural, and social amenities within a single, cohesive complex. The Barbican Estate example exemplifies planned unit developments where various amenities such as art centers, theaters, gardens, and commercial spaces are designed to coalesce into a comprehensive community environment.

This holistic focus on convenience and community interaction is a hallmark of the Barbican development, aiming to foster an urban lifestyle that is both self-sufficient and engaging. The other concepts mentioned—Metabolism, Neighborhood Unit, and Marine City—are important in architectural history but do not specifically embody the same level of integration of diverse amenities within a singular compound as expressed in the Barbican development.
