Abstract
This paper is one of the comprehensive researches to explicate Geoffrey Bawa's architectural thought and works. The aim of this paper is to focus on thematic explication through the analysis on the spatial composition of his hotel works. The analysis consists of 4chapters as follows: Chapter2-4 describes the properties and their chronological modification viewed from the connection between outside and inside, and between adjacent spaces by analyzing two diagrams. Chapter5 explores his architectural theme through the semantic analysis of the interrelationship of those properties and its modification revealed in his spatial composition. Finally, this paper explicates the meaning of intermediate spaces which play the key role in Geoffrey Bawa's architectural works.
