This document discusses various aspects of circulation and movement through spaces in architecture. It covers approaches to buildings from a distance, types of entrances, configurations of interior spaces, relationships between paths and spaces, and different forms for circulation spaces like corridors, halls, galleries and stairways. Key points include different types of approaches like frontal, oblique and spiral; entrance styles like flush, projected and recessed; common space configurations like linear, radial and grid; and how circulation spaces can be closed, open on one side or both sides. Stairways are also examined in terms of their forms and how they provide vertical movement between levels.
