This research starts from the questioning of current housing development situation on hilly sites in Korea. It aims to investigate various design techniques of terraced housing as an alternative housing type on sloped sites. Several generic solutions are proposed, as for site slope and stacking method, combination of dwelling units, access pattern, and sectional variation of unit space. By the comparative analysis of design proposals with the typical two-row vertical-access type, the efficiency of the proposed techniques are verified in terms of development density, provision of community space, habitability of dwelling units.
