Abstract
This study aims to explore a room for improvement for future townhouse development in Jeju, especially in terms of architectural planning and design. For this purpose, 14 Jeju townhouse cases built before or proposed after 2014 were scrutinized to find out current problems commonly disclosed. The notable shortcomings were summarized as follows: the lack of 'guesthouse' concept, poor guidelines for community space planning, inadequate establishment of communal estate management system and finally the lack of versatile plan to accommodate various types of resident groups. At the end, it is suggested to establish 1) institutional criteria for promoting the desirable townhouse development in Jeju and 2) short-term rotating tenancy system enabling residents to move easily to another tenancy of their favorite area. Concurrently, the use of local resources is recommended in order to incorporate low-energy consuming design concept for future sustainability.
