The RC Houses serve as the foundation for the KENTECH undergraduate experience. All undergraduates live in one of the two residential RC Houses. Each House accommodates 200~250 students with its community rooms and facilities for academic, social, and cultural activities. Each community within the two houses represents KENTECH society, offering students a sense of belonging, intimate social and intellectual connection, and a space of civic and moral responsibility.

The Masters of houses, typically senior faculty members, take charge of RC houses and shape students' social and intellectual lives. Together with affiliated KENTECH faculty members, RC staff, fellows, graduate affiliates, and alumni, they work to make the RC Houses warm and supportive communities where students can explore and experience all that KENTECH and the city of Naju have to offer.
