This research starts from the questioning of current housing development on the hilly site in Korea. It aims to investigate various design techniques of low-rise housing as an alternative housing plan on hilly sites. Several generic solutions of the combination of building type and road pattern are tested for a simulation process, and evaluated in terms of crucial design issues; development density, parking space and open space. As a result, four reasonable models are selected for making full use of geographical features of hilly site, two models each land slope of $18^{circ}$ and $26^{circ}$. Several design techniques for each model are also suggested, in ensuring the development feasibility by considering land slope, vehicular access and parking, common open space, and community facilities.
