This document discusses different types of spatial arrangements in architecture, including centralized, linear, radial, clustered, and grid organizations. A centralized organization groups secondary spaces around a central space. A linear organization arranges spaces in a series along a line or linear path. A radial organization extends spaces from a central point along radial arms. A clustered organization relates spaces through physical proximity. A grid organization regulates the position and relationship of spaces using a three-dimensional grid pattern.
