High-Rise Modular Unit System is a product development proposal for a high-rise modular housing system based on structural innovation and unit integration. The project responds to the limitations of conventional modular construction in Korea, where modular housing has often relied on repetitive stacking, rigid layouts, and apartment plans borrowed from conventional concrete housing systems. As the market expands toward mid- and high-rise modular buildings, the proposal argues that modular construction requires not only standardized production, but also a flexible structural and spatial system.
The research focuses on diversifying modular construction methods beyond simple stacking. Infill-type systems and cartridge-type systems are examined as alternatives that can improve structural stability, reduce floor impact noise, and allow individual units to be replaced or maintained more easily over time. In parallel, the proposal develops interior unit types that can be applied across different modular plans rather than being limited to a single unit layout.
The unit system is organized into three categories: service units, flexible units, and balcony units. Service units integrate equipment and structural systems to improve functionality and constructability; flexible units support different spatial configurations through modularized interior functions; and balcony units operate as independent exterior attachments that consider insulation, drainage, and façade performance. Through this approach, the project establishes a scalable framework for high-rise modular housing that can support mass production, customization, long-term maintenance, and future commercialization.
