Through the dialogue between new and old materials, and the continuation of existing textures of memory, sustainable design expresses the crucial concept of family heritage. The imagery of a spiraling staircase gave birth to the design inspiration for a ‘family tree,’ combining the concept of ‘family symbiosis’ with the homeowner’s family of ten. It glimpses the possibilities existing within the space, not only integrating the preferences and personalities of each family member but also ensuring that every individual space is as versatile as branches, fulfilling various functionalities of life.
