This document discusses housing layout plans and public facilities. It describes basic building forms like blocks, towers, and courtyard apartments. Blocks are wider than they are tall with apartments arranged along a central corridor. Towers have a vertical form and centralized zone. Courtyard apartments provide side open spaces like communal courtyards. Rectilinear street grids create uniform blocks and intersecting streets, while cul-de-sacs are closed roads with one inlet/outlet. Public facilities provided by the government include services that cannot be supplied to individual homes, and satisfy community needs for safety, communication, recreation, education, health, culture and administration.
