Having accumulated experiences of designing collective housing with many projects of private houses for factories, Junglim Architecture began to collaborate with Korea National Housing Corporation since the late 1970s. Since designing the floor plans for KNHC Dunchon Apartment and KNHC Dogok Apartment by area types, we mainly worked on high-rise apartment housing amongst the KNHC projects. Representative examples include the high-rise types of Hannam International Apartment and KNHC Gwacheon Apartment.
