SKYSYSTEM has spent 26 years moving forward quietly with a single belief: a home should truly feel like home. For that reason, it does not accept bathroom noise between floors as something inevitable. Like the living room or the bedroom, the bathroom is also part of one’s home. Skysystem identified and addressed the structural flaws of bathrooms in multi unit housing. It found that shared, non independent piping systems were the source of the noise, and ultimately developed the On Slab Piping System (OSP).

We designed the catalogue <A Proposal for a Premium Bathroom for Hannam District 3>, which introduces the OSP system to be applied to Hannam District 3. The content was carefully refined and edited to make the structure, components, and principles of OSP easy to understand.
