Interior Space and Exhibition Design Hollow Valley Residence by Weifeng Ni Hollow Valley is a residential interior design for a family of six in Wenzhou, Zhejiang. The home covers 900 square meters and is arranged to balance the lifestyles of two generations. The original building structure was cut and reorganized into geometric blocks, forming crisscrossing paths. A deconstructed staircase with misplaced treads carries light between the floors. The dining and kitchen areas are separated by an elongated central island that offers storage and acts as a gathering point. The island also guides movement through the space like a corridor.
