This document provides an agenda and instructions for a unit on planning interior spaces. It includes discussing a bubble diagram and adjacency study to help determine room relationships. Students are asked to create a bubble diagram for their apartment design project by drawing labeled circles of different sizes to represent rooms. They should consider the room hierarchy and categorize spaces as public, private, workspace or storage. Link lines of varying thickness will show room relationships based on the adjacency study. The homework is to finalize this bubble diagram with labels, arrows and color coding to help plan the overall apartment design.
