This document contains lecture notes on external walls and roof construction for a technology education course. It discusses various types of ground floor construction including solid concrete floors, suspended timber floors, and precast concrete floors. It also covers primary types of residential construction in Ireland using concrete cavity walls or timber frame construction. Different aspects of external wall, internal floor, stairway, and roof construction are outlined through diagrams and descriptions.
