Interior Space and Exhibition Design Serenity Residential by Pohui Lin Serenity is a residential interior design for a family apartment of 118 square meters. The entrance is centered on natural marble veining, which forms a discreet and elegant focal point. Solid wood, water-stained oak, engineered quartz and natural stucco shape a warm interior, and the stucco helps control humidity for energy efficiency. Low-formaldehyde and low-VOC materials were selected. A versatile hub serves both work and play, while a separate quiet room offers privacy. Open paths and abundant natural light support shared family life.
