This is a small-scale residential design project with a focus on children’s growth. In Hong Kong, where land is scarce, living spaces have become increasingly compact. However, children are the future pillars of society and play an important role in the family. Providing them with a joyful childhood is the initial aspiration of this project’s design. “Little Home” plays a crucial role in children’s growth process by assisting in their cognitive development, redefining spatial boundaries, incorporating novel material combinations, flexible storage furniture, sustainable development concepts, and home safety designs. These design elements, combined with references to the client’s previous residences, current lifestyle patterns, and considerations for future family plans, create a new generation of small-scale residential design. Through this, we can reflect on the role of small home design in today’s society and its impact on personal growth.
