Which design element does Habitat 67 utilize according to the concept of additive transformation?

Habitat 67, designed by architect Moshe Safdie, is a notable example of the concept of additive transformation, which refers to the combination and arrangement of elements to create a cohesive structure. In this case, the design utilizes cluster form as it consists of prefabricated modular units that are stacked and arranged to create both individual apartments and communal spaces. This approach promotes a sense of community while allowing for varied living experiences.

The clustering of the modular blocks creates distinct living environments that exemplify spatial complexity and interconnectivity. By using these units in a clustered arrangement, Habitat 67 emphasizes the relationships between the different living spaces and their integration with outdoor areas, enhancing both privacy and interaction among residents. This aligns with the additive transformation concept, where the whole is greater than the sum of its parts, producing a dynamic and engaging urban habitat.

In comparison, while linear form, modular blocks, and geometric configuration can contribute to architectural design, they do not specifically encapsulate the essence of how Habitat 67 organizes its spaces and promotes community through its cluster arrangement. Consequently, cluster form is the key design element reflecting the principles of additive transformation in this iconic architectural work.
