What is the term for areas where factories are clustered together?

The term for areas where factories are clustered together is "industrial estates." Industrial estates are specifically designated areas for industrial activity, often providing the necessary infrastructure and services to support manufacturing and production processes. These areas are typically located outside of urban centers to reduce congestion and provide larger spaces for factories. An industrial estate usually comprises various manufacturing facilities, warehouses, and distribution centers that share resources such as transport links and utilities.

This clustering allows for efficiencies in logistics and operations, as businesses can benefit from reduced transportation costs, shared services, and proximity to suppliers and customers. The planning of industrial estates enables companies to operate in an environment that is conducive to their needs, which is central to their function and success in the economy.

In contrast, residential districts are primarily designed for housing, commercial zones pertain to areas focused on retail and service industries, and business parks often include a mix of office space and light industrial activities, rather than the dense factory setup characteristic of industrial estates.
