ABSTRACT
Based on 56 surveyed HTGHs, standard layout of them can be divided into 4 parts: nha chinh (main house), nha phu (sub-house), garden and other elements1. nha chinh can be divided into two parts: gian (chamber) and chai (lean-to). The surveyed HTGHs can be classified into 3 types according to the number of gian and chai as shown in figure 2: 1 gian-2 chai (A type), 3 gian-2 chai (B type), and 3 gian (C type). The structure of nha chinh is normally made of timber. nha phu is usually laid perpendicularly to nha chinh. From the survey, there exist four layouts of arrangement between nha chinh and nha phu as illustrated in table 1.
