The TCIS campus is designed to support learning, creativity, community, and student wellbeing. Located on a peaceful 10-acre hillside overlooking Daejeon’s Daedeok Techno Valley, the purpose-built campus combines modern educational facilities with green spaces and views of the surrounding landscape.

Classrooms and collaborative learning areas support inquiry, discussion, project work, and the thoughtful use of technology. Specialized spaces for science, design, visual arts, performing arts, music, and technology give students opportunities to experiment, create, solve problems, and share their learning. The school library provides a welcoming environment for reading, research, independent study, and collaboration.

Athletic facilities support physical education, team sports, recreation, and school competitions. Indoor and outdoor spaces allow students to remain active throughout the year, while common areas, performance spaces, and gathering places bring students, families, and staff together for events, celebrations, and shared experiences.

Purpose-built residences support the Grades 6–12 boarding program. Students live in a structured, caring environment with nearby resident staff, supervised study areas, shared community spaces, and convenient access to academic and extracurricular facilities. This integration allows learning, activities, friendships, and personal support to continue beyond the school day.

The campus is large enough to provide diverse opportunities while remaining close-knit and easy to navigate. Its design helps students feel known and connected, move confidently between learning experiences, and participate fully in the academic and community life of TCIS.
